What do you need to know about sun creams? A doctor explains

The importance of sun protection

• The sun protection plays an extremely important role in our health and should be taken seriously by everyone. Although sunlight has many positive effects on our body and soul, the harmful UV rays can also have serious consequences. It is therefore essential to protect ourselves from them.
• The sun is not only a major source of vitamin Dwhich is important for bone and immune function, but it also boosts our mood and ensures better overall health. Nevertheless, we should be aware that excessive sun exposure can lead to sunburn, premature skin ageing and even skin cancer.
• It is advisable to protect yourself effectively, sun creams with a high sun protection factor. These should be applied regularly, especially after swimming or sweating. In addition, you should stay in the shade, wear hats and sunglasses and avoid sunny midday hours when the sun's rays are strongest.
• The importance of sun protection cannot be emphasized enough, as it has a direct impact on our health. By protecting ourselves from harmful UV rays, we can enjoy the positive effects of sunlight while minimizing the risk of skin damage and disease.

The role of sun creams in the prevention of skin cancer

• Sun creams play an important role in the prevention of skin cancer. Skin cancer is the most common form of cancer worldwide and is closely linked to harmful UV radiation. Sun creams protect the skin from the harmful effects of UV rays, including sunburn, premature skin ageing and the development of skin cancer.
• There are some important facts to keep in mind when using sun creams should be considered. Firstly, it is important to use a sun cream with a sufficiently high sun protection factor (SPF). The SPF indicates how well the cream protects against UV radiation. An SPF of at least 30 is recommended for daily use and even higher for longer stays in the sun.
• Secondly, the sun cream should be applied regularly and generously. It is important to apply the cream about 30 minutes before sun exposure to ensure adequate protection. It should also be reapplied every two hours and after swimming, as it can lose its effectiveness over time.
• To summarize Sun creams play an essential role in the prevention of skin cancer by protecting the skin from the harmful effects of UV rays. Important factors in the use of sun creams are the sun protection factor and regular application. It is important, sun creams as part of a comprehensive sun protection measure, which also includes wearing protective clothing and avoiding the most intense hours of sunshine.

Understanding sun protection factors

• With sun creams it is important to pay attention to various factors to ensure adequate protection from the sun's harmful UV rays. The sun protection factors (SPF) play a decisive role here. These indicate how long you can protect yourself with the respective cream in the sun without getting sunburnt. The higher the SPF value, the longer you can stay in the sun without protective clothing. Most experts recommend an SPF of at least 30 to ensure adequate protection. Another important consideration is UVA protection. In addition to UVB rays, UVA rays are also responsible for skin damage such as premature skin ageing or skin cancer. It is therefore important that a sun cream offers sufficient UVA protection. The application of the sun cream also plays a role. It should be applied generously and regularly to ensure adequate protection. It is also important to sun cream in good time before sunbathing and to reapply it regularly after swimming or sweating. These measures can ensure that you are effectively protected from harmful UV rays.

High sun protection factors

• High sun protection factors are of great importance when it comes to protection against the harmful effects of the sun's rays. The sun protection factor (SPF) provides information on how well the sun cream protects against UV-B rays, which are primarily responsible for sunburn. A high SPF therefore means intensive protection against sunburn.
• However, it is important to note that sufficient UV-A protection must also be provided. UV-A rays are responsible for premature skin ageing and the formation of skin cancer and can also contribute to skin tanning. Therefore sun cream should also contain a UV-A filter.
• To ensure that sufficient UV-A protection is provided, it is important to check the labeling of the sunscreen. sun cream labeling. The packaging should contain information that sufficient UV-A protection is provided. An important symbol for this is a circle with an "A" or "UVA" in it. This symbol indicates that the sun cream also protects against the UV-A rays that cause tanning.
• When choosing a sun cream not only the sun protection factor, but also the UV-A protection and the corresponding labeling on the packaging should be taken into account. This is the only way to ensure effective and comprehensive protection against the harmful effects of the sun's rays.

The right sun protection factor for your skin type

• The sun protection factor (SPF) plays an important role in protecting our skin from harmful UV radiation. Depending on your skin type and the intensity of the sun, you should choose the right SPF to ensure adequate protection.
• The SPF indicates how well the sun cream protects against UV-B rays. The higher the SPF, the greater the protection against sunburn. It is important to note that the SPF does not increase linearly with the protective effect. For example, an SPF 30 blocks around 97% of UV-B radiation, while an SPF 50 blocks around 98%. An SPF over 50 no longer offers significantly higher protection.
• To determine the right SPF, it is important to know your own skin type. There are different skin types that differ in terms of their natural skin protection against UV radiation. People with very fair skin or sun allergies have a higher need for protection and should use a sun cream with a higher SPF, such as SPF 50 or 50+. People with darker skin can often fall back on a lower SPF, such as SPF 15.
• The right SPF for your skin type is therefore crucial to protect your skin from sun damage. It is important to determine your own skin type and choose the right sun cream with the appropriate SPF to ensure optimum protection.

The so-called sun protection factor

• The so-called sun protection factor (SPF) is an important indicator for determining protection against harmful UV radiation from the sun. sun creams by sun creams. It indicates how much longer you can protect yourself with the applied sun cream can stay out of the sun without getting sunburned compared to unprotected skin. The calculation of the SPF is based on the ratio of the determined minimum skin redness with and without sunscreen. For example, an SPF 30 means that with sun cream 30 times longer in the sun without risking sunburn than without protection.
• It is important to adjust the sun protection factor according to your own skin type and UV index to ensure effective protection. People with fair skin or blonde hair are generally more sensitive to UV radiation and require a higher SPF. The UV index also plays an important role, as it indicates the intensity of UV radiation in a particular place and at a particular time. On sunny days in summer with a high UV index, a higher SPF is required, while on cloudy days with a low UV index, a lower SPF may be sufficient.
• It is advisable to determine your own skin type and check the UV index for your location before sunbathing in order to select the optimum sun protection factor. This allows you to effectively protect your skin from harmful solar radiation and possible sunburns.

Types of filters in sun creams

Sun creams are an important part of our sun protectionespecially during the summer months. When choosing a suitable sun cream there are a few important points to consider. In this article, we will look at the different types of filters in sun creams in sun creams.

Types of filters in sun creams:

1. Chemical filters: These filters absorb UV rays and convert them into heat. They penetrate the upper layers of the skin and offer protection against UVA and UVB rays. Common chemical filters include octinoxate, oxybenzone and avobenzone.
2. Physical filters: These filters reflect UV rays and prevent them from penetrating the skin. They create a protective layer on the surface of the skin. The two best-known physical filters are titanium dioxide and zinc oxide. They offer protection against UVA and UVB rays and are particularly suitable for sensitive skin.
3. Broadband filters: Sun creams with broadband filters offer protection against both types of UV rays, UVA and UVB. These filters are usually included in most sun creams to ensure comprehensive protection against sun damage.

When choosing a sun cream it is important to note that the sun protection factor (SPF) indicates the intensity of protection. The higher the SPF, the longer we can be exposed to the sun without getting sunburnt. It is also advisable to use a waterproof sun cream especially when we are in the water or sweating. In addition, the sun cream should be reapplied regularly, every two hours and after swimming, to maintain continuous protection.

Overall, it is important to consider the different types of filters in sun creams to ensure the right protection for our skin. By choosing a sun cream with suitable filters and SPF and applying it regularly, we can protect our skin from sun damage and an increased risk of skin cancer.

Mineral filters

• In the area of the sun protection there are various types of filters, including mineral filters. These filters are based on ingredients such as titanium dioxide and zinc oxide and offer physical protection against harmful UV rays. Unlike chemical filters, which absorb the UV rays and convert them into heat, mineral filters work by reflection. They form a protective layer on the skin that bounces off the UV rays. This prevents the rays from reaching the skin in the first place and therefore cannot cause any damage.
• There are now several companies that offer mineral sun protection without the undesirable whitening effect. One of these, for example, is the brand "La Roche-Posay" brand. Their mineral sun creams have a very fine texture and spread well on the skin without leaving a white film. The brand "Avène" also offers mineral sun creams which are quickly absorbed and do not leave a white effect. These mineral sun creams are particularly suitable for people with sensitive skin. sun protection products a good alternative to chemical filters.
• In summary, it can be said that mineral filters have a physical effect and reflect UV rays instead of absorbing them. As a result, they offer effective protection against sunburn and damage caused by UV rays. Companies like "La Roche-Posay" and "Avène" have mineral sun protection without the undesirable whitening effect, making it a good choice for anyone who wants to avoid chemical filters.

Chemical filters

• Chemical filters are an essential component in sun creams and are used to protect the skin from the harmful effects of the sun's UV rays. There are different types of chemical filters that are used in sun creams used in sun creams to ensure effective protection.
• Commonly used chemical filters include oxybenzone, avobenzone, octinoxate and octisalate. These substances work by absorbing the UV rays and releasing them from the skin in the form of heat energy. This prevents the rays from penetrating the skin and causing damage.
• However, there are also potential risks and concerns associated with the use of chemical filters in sun creams. Some studies have shown that certain chemical filters can trigger allergic reactions, especially in people with sensitive skin. It is also known that some of these substances have hormonal effects and can influence the endocrine system.
• It is important to minimize these risks, sun creams with a broad spectrum of UV filters that combine various chemical and physical filters. You should also sun cream regularly and generously, especially after swimming or sweating, to maintain protection.
• Overall, chemical filters in sun creams are an effective way to protect the skin from the harmful effects of the sun. However, the potential risks and concerns should be considered in order to choose the best sunscreen for your individual needs.

Physical filters

• Physical light protection filters such as titanium dioxide and zinc oxide offer an effective way of protecting the skin from harmful UV radiation. The advantage of these filters is that they are effective immediately after application, as they reflect and scatter sunlight instead of absorbing it. This protects the skin from UV radiation.
• Titanium dioxide and zinc oxide work by converting UV radiation into heat. This chemical reaction takes place directly on the skin and prevents the UV rays from penetrating the skin and causing damage. The light protection filters form a protective layer on the skin that reflects and scatters the sun's rays instead of absorbing them. This effect ensures that the skin remains protected and is not damaged by the harmful UV rays.
• Physical light protection filters provide effective protection against both UVA and UVB rays. As these filters do not penetrate the skin, they are also suitable for sensitive skin types. It is important when buying sun creams to check the titanium dioxide and zinc oxide content to ensure that the desired skin protection is provided. It is also advisable, sun creams regularly and generously on the skin to maintain protection. Overall, physical light protection filters such as titanium dioxide and zinc oxide are effective means of protecting the skin from harmful UV radiation and should therefore be considered when choosing sun creams should be taken into account.

Organic filters

• Organic filters are based on natural substances to remove pollutants from liquids or gases. They can consist of various materials such as activated carbon, zeolite and other organic substances.
• One example of the use of organic filters is water purification. The use of activated carbon filters removes impurities and pollutants such as chlorine, pesticides or drug residues from the water. Activated carbon is a porous carbon that has the ability to bind pollutants to its surface and thus filter them out of the water.
• Another example of the use of organic filters is air purification. Here, organic filters such as zeolite are used to remove odors and harmful gases. Zeolite is a natural substance that has the ability to absorb and store molecules. By using zeolite filters, pollutants can be removed from the air, which is particularly important in enclosed spaces such as offices or homes.
• Organic filters offer an effective way of removing pollutants from liquids or gases. By using natural substances such as activated carbon or zeolite, they can help to protect the environment and improve people's health.

Skin cancer and sun exposure

• Skin cancer is a serious disease that can be caused by overexposure to the sun. UV radiation from the sun is one of the main factors in the development of skin cancer. If the skin is exposed to the sun for long periods of time, the cells are damaged and there is an increased risk of developing skin cancer.
• There are different forms of skin cancer, including basal cell carcinoma, squamous cell carcinoma and malignant melanoma. Basal cell carcinoma is the most common form of skin cancer, usually occurring on the face or other sun-exposed areas of the body. Squamous cell carcinoma often occurs on areas that are heavily exposed to the sun, such as the scalp or the back of the hand. Malignant melanoma is the most dangerous form of skin cancer and can be fatal.
• To protect yourself from skin cancer, it is important to take sun protection measures. This includes the regular application of sun cream with a high sun protection factor, especially for prolonged exposure to the sun. Direct sunlight should also be avoided, especially at midday when UV radiation is at its strongest. It is also advisable to wear protective clothing such as hats, sunglasses and long-sleeved clothing.
• Regular skin cancer screening is extremely important in order to detect signs of skin cancer at an early stage. Regular examinations by a dermatologist can help to diagnose skin cancer at an early stage and thus improve the chances of recovery.
• Overall sun protection and regular skin cancer screening is essential to minimize the risk of skin cancer and protect the health of the skin.

Development of skin cancer

• Skin cancer is a common form of cancer caused by overexposure to ultraviolet radiation. The development of skin cancer occurs in different stages, which are influenced by certain factors. A major cause of skin cancer is exposure to the sun, especially long-wave UV-A rays, which can directly damage skin cells.
• When exposed to the sun without adequate protection, UV rays can attack the genetic material of skin cells and cause mutations. These mutations lead to changes in the genetic material that can impair the growth and function of the cells. Some of these mutations can lead to malignant tumors.
• Skin cancer develops in different stages. In the early stages, some atypical cells are formed which differ from normal skin cells. Later on, a preliminary stage of skin cancer, known as actinic keratosis, can develop. These lesions are already precancerous and should be treated to prevent further development.
• If the mutations and genetic changes continue, actinic keratosis can develop into squamous cell carcinoma or basal cell carcinoma. These forms of skin cancer are already malignant and require more extensive treatment.
• It is important to take protection from the sun seriously and take appropriate precautions to reduce the risk of skin cancer. The use of sunscreen with adequate UV protection is an easy way to protect the skin from harmful rays. In addition, sun exposure should be avoided during the hottest hours of the day and protective clothing should be worn. These measures can significantly reduce the risk of skin cancer.

How much cream is enough?

• To sufficiently moisturize the whole body with sun cream it is important to use the right amount. As a guideline, adults should apply around 40 milliliters of sunscreen are needed. But what is the best way to visualize this amount?
• One way is to measure the amount in shot glasses. One portion of sun cream is roughly equivalent to one shot glass. You should therefore use about two shot glasses for your entire body. sun cream should be used. This amount may seem a lot at first glance, but it is necessary to ensure adequate protection.
• Another way to determine the right amount is the so-called two-finger rule. This involves using a generous amount sun cream and spread it over two fingers. This amount should be enough to protect an area about the size of the back of your hand.
• It is also important to note that the sunscreen must be renewed regularly. In particular, the cream should be reapplied after swimming, drying off or sweating. Even if a product is described as "waterproof", this only means that half of the sun protection is retained. It is therefore advisable to sun protection every two hours to ensure continuous protection from harmful UV rays.

Is expensive better?

• The question of whether more expensive sun protection products are actually better is a question that concerns many people. It is often assumed that a higher price automatically means better quality and protection from UV rays. However, this is not necessarily the case. It is much more important to pay attention to the sun protection filters they contain. These are crucial for protecting the skin from harmful radiation.
• When selecting sun protection products various criteria should be taken into account. Firstly, it is advisable to ensure that the sun protection factor (SPF) is sufficient. Depending on skin type and sun intensity, a higher or lower SPF is recommended. Furthermore Sun protection products should contain broadband filters to protect against UV-A and UV-B rays.
• To ensure that a sun protection product offers the desired protection, product tests can be helpful. These are carried out regularly by independent institutions and provide information on the effectiveness of different products. However, it should be noted that an expensive product does not necessarily have to perform better than a cheaper one.
• Finally, it should be noted that expensive sun protection products are often available in perfumeries. This often leads to higher prices due to additional brand and marketing costs. Ultimately, it is crucial to pay attention to the sun protection filters and the individual need for sun protection factor rather than judging solely on price.

Cream, oil or spray?

• When choosing a sunscreen there are various options such as cream, oil or spray, which have advantages and disadvantages depending on the individual needs of the skin.
• The advantage of a cream is that it spreads well and has a long-lasting effect. It can also moisturize and thus soothe dry skin. However, it can sometimes be a little difficult to apply and leave a greasy feeling on the skin.

• Sprays are particularly practical to use as they are easy to spread and leave no greasy residue. However, there is a risk of a thin protective film with sprays, as often not enough product is applied. It is therefore important to spray the spray densely enough onto the skin and to spray several times if necessary.
• There are various sun protection factors (SPF) to choose from, depending on how long the skin's own individual protection time is. A lower SPF such as 15 may be sufficient if the skin is less sensitive to the sun or if the sun exposure is short. For very sensitive skin or longer sun exposure, a higher SPF or even a sunblock is recommended.
• Regardless of the form of sunscreen product it is important to maintain a sufficient dosage and regular application to ensure reliable protection. It is also advisable to follow the individual recommendations for different skin types.

May normal sun cream on the face?

• Normal sun cream can generally also be used on the face, but there are special sun protection face creamsthat offer certain advantages. These creams are often lighter and less greasy than normal ones sun creamwhich means they are better absorbed by the skin and feel more comfortable. They also often contain special ingredients that provide additional care and protection for the skin.
• In comparison, normal sun cream However, it makes more sense than wrinkle cream as it offers better and more comprehensive protection against harmful UVA rays. These rays are the main cause of premature skin ageing and can be prevented by sun cream be effectively warded off. Thus sun cream not only prevents wrinkles, but also other signs of premature skin ageing.
• When storing sun cream it is important to keep it in a cool and dry place. Heat and sunlight can impair the effectiveness of the cream. You should also sun cream from the previous year should no longer be used, as it may have lost its protective effect. It is therefore advisable to sun cream regularly and replace it if necessary.

• Another way to protect the skin from the inside out is to take sun protection products with the active ingredient Polypodium Leucotomos. This natural extract from a medicinal plant strengthens the skin and helps it to defend itself against harmful UV rays.
• In summary, if you have sensitive skin, it is advisable not to spend too much time in the sun and to avoid wearing textiles. sun protection and use textile sun protection. You should also sun creams with a high UV protection factor and mineral filters. The use of sun protection products containing Polypodium Leucotomos can provide additional protection from the inside out. This is the best way to protect the skin from sun damage.

Special protection for children?

What is important for sun creams to consider

• On the subject of sun protection and sun filters, special protective measures are particularly important for children. Children's skin is thinner, more sensitive and does not yet protect itself as well against UV radiation as adult skin. Special care should therefore be taken when spending time in the sun.
• To protect children's skin in the best possible way, it is advisable to sun cream with a high sun protection factor (SPF). The SPF indicates how well the skin is protected from UV rays. The higher the SPF, the better the protection. Care should also be taken to ensure that the sun cream is waterproof to ensure adequate protection even when swimming or sweating.
• In addition to the sun cream it also makes sense to equip children with sun protection clothing. This includes, for example, T-shirts with long sleeves, hats with wide brims and sunglasses with a UV filter. These items of clothing offer additional protection against harmful UV radiation.
• Chemical sun filters should be avoided as far as possible for young children. These can cause allergic reactions or skin irritation. Instead, it is advisable to use physical light protection filters. These cover the skin like a protective film and reflect the UV rays. The disadvantage of these filters is that they are partially visible and can leave a white film.
• Overall, it is important to protect children's sensitive skin from the sun. With sun creamsunscreen, sun-protective clothing and the right SPF can make a contribution to children's health.

What soothes after sunbathing?

• After sunbathing, it is important to soothe and care for the skin. After-sun products are specially developed for this purpose and contain various ingredients that help.
• Some after-sun products contain anti-inflammatory substances such as aloe vera or witch hazel. These have a calming effect on the skin and soothe any irritation or redness. Glycerin and panthenol are often used to moisturize the skin and support its regeneration process.
• Some after-sun products also contain DNA repair enzymes that help to repair possible damage to the skin caused by UV radiation.
• When sunbathing, the skin can be exposed to various influences. The sun's UV rays can damage the skin and lead to sunburns, for example. The tanning of the skin is regulated by the pigment melanin, which serves as natural protection against UV radiation.
• Nevertheless, UV radiation can have harmful effects and lead to damage to the epidermis. In the long term, this can increase the risk of skin cancer, and UV-A rays in particular are known to do so.
• It is therefore important to protect the skin from the sun and to regularly sun cream with an appropriate sun protection factor. After sunbathing, the skin should be treated with after-sun products to soothe any irritation and calm the skin.

What to do in case of sunburn?

• If you have a sunburn, you should take a few steps to alleviate the discomfort. One of the most important measures is to cool and soothe the affected skin. You can do this by applying moist compresses with cool water to the burnt area. It is also advisable to apply nourishing lotions without fragrances to hydrate and soothe the skin.

• Overall, it is important to protect yourself and especially your skin from sunburn. Through suitable sun protection measures and appropriate treatment, we can avoid unpleasant consequences.

The first myth - the sun cream from last year still works

• On the subject of sunscreen there is a widespread myth, namely that the sun cream from last year can still be used. But this is not always true. The effectiveness of sun cream depends heavily on its best-before date. UV protection can be guaranteed up to this date. After this date, protection may be reduced due to changes in the ingredients.
• However, there are factors that can be used to recognize whether the sun cream can still be used or not. For example, the sun cream should have the same smell and consistency. If the cream looks different or smells strange, it is better not to use it. Another factor is heat exposure. If the sun cream exposed to extreme temperatures, this can affect its effectiveness.
• To ensure that the sun cream offers the best possible protection, it is therefore important to check the best-before date and look out for signs of change. The myth that the sun cream from last year is still good should not be believed.

The third myth - the higher the sun protection factor, the less tanned you get

• The third myth is that the higher the sun protection factor sun cream with a higher sun protection factor. However, this statement is false. In fact, the sun protection factor (SPF) has nothing to do with the tanning of the skin. The SPF merely indicates how well the sun cream protects against UV-B rays, which are responsible for sunburn. UV-A rays, on the other hand, are responsible for tanning the skin and are often not sufficiently protected by sun creams protected by sun creams.
• The connection between the SPF and the tanning of the skin lies rather in the fact that a higher sun protection factor sun cream protects better against sunburn. As a result, the skin is not damaged by redness, pain or even blistering and tanning can take place more evenly. However, it is important to note that a higher SPF does not provide complete protection against UV rays and the skin can still be damaged.
• When choosing a sun cream it is therefore important to pay attention to various factors. Firstly, the sun protection factor should be appropriate, depending on the skin type and intensity of sun exposure. In addition, the sun cream offer sufficient protection against UV-A rays, as indicated by the UVA symbol on the packaging. It is also advisable to use waterproof sun creams to maintain protection when swimming or sweating. Additional ingredients such as antioxidants can also be beneficial to protect the skin from premature ageing.
• Overall, it is important to use a sun cream according to individual needs to ensure effective protection against UV rays and at the same time allow the skin to tan healthily.

The fourth myth - you don't need to apply sunscreen in the shade

• The fourth myth is that you don't need to apply sunscreen in the shade. But this is wrong. Even if it is cloudy and you are in the shade, you are still exposed to UV-B and UV-A rays. These rays can damage the skin and lead to sunburn, premature skin ageing and even skin cancer.
• One example of this is reflected sunlight, which can reach the skin through water surfaces and white sand, even in the shade. These are dangers that are difficult to recognize, as many people believe that they are not exposed to sunlight in such situations. sun protection need sun protection in such situations.
• It is important to understand that sunscreen not only serve to protect us from direct sunlight, but also from indirect sunlight. It is therefore essential, sun cream even in the shade and on cloudy days. The use of a sunscreen with a high sun protection factor (SPF) of at least 30 is advisable to ensure adequate protection against harmful UV rays.
• In short, the myth that you don't need to apply sunscreen in the shade is false. UV-B and UV-A rays can damage the skin even in the shade. Therefore, you should always wear sun cream with a sufficient sun protection factor to protect yourself from these dangers.

The fifth myth - solarium tanning forms a foundation

• The myth that a tan in a solarium forms a healthy foundation for the skin is unfortunately false. On the contrary, intense UV-A rays can have serious long-term health effects.
• The desire for a beautiful tan tempts many people to go to a solarium and expose themselves to intense UV-A rays. However, these rays penetrate deep into the skin and can cause serious damage. In addition to accelerated wrinkling, the risk of developing skin cancer increases considerably.
• The long-term effects on health should not be underestimated. The tanning bed tan only gives a short-term and superficial color, which offers no protection against the harmful UV rays. On the contrary, the skin is weakened and cannot adequately protect itself from the harmful effects of the sun.
• It is therefore strongly recommended that you avoid the solarium and instead make sure you get enough sun exposure. sun protection instead. Regular application of sunscreen with sun cream with a high sun protection factor is essential to protect the skin from the negative effects of intense UV rays. This is the only way to ensure the long-term health of the skin.

The sixth myth - sun protection promotes vitamin D deficiency

• A widespread myth says that the use of sunscreens can lead to a vitamin D deficiency. This belief is based on the assumption that sunscreen blocks the influence of the sun's rays on the skin and thus prevents the production of vitamin D.
• However, numerous studies have shown that sunscreen have no significant influence on the vitamin D concentration in the blood. Even with regular and correct use of sun creams vitamin D synthesis is not impaired.
• It is important to note that short-term and protected sun exposure is sufficient to ensure adequate vitamin D production. Just a few minutes of sun exposure on unprotected skin can be helpful. However, if a vitamin D deficiency is suspected, a risk-benefit analysis should always be carried out by a doctor in order to assess the possible consequences and, if necessary, take oral supplementation.
• In summary, it can be said that sunscreen have no demonstrable influence on the vitamin D concentration in the blood. Short-term and protected exposure to the sun is sufficient to cover the need for vitamin D requirements. However, medical advice should always be sought in the event of a possible deficiency.

The seventh myth - only sunburn promotes skin cancer

• The seventh myth I would like to clear up is that only sunburn promotes skin cancer. Unfortunately, this is not true. Numerous studies have shown that UV-A rays, which do not cause sunburn, are also involved in the development of skin cancer.
• UV-A rays penetrate deeper into the skin, where they can accelerate the ageing process and cause cell damage. This damage can lead to skin cancer, even if no sunburn occurs. Protection from UV-A rays is therefore just as important as protection from UV-B rays, which are responsible for sunburn.
• It is crucial that sun creams provide adequate protection against both UV-A and UV-B rays. When buying a sun cream pay attention to the sun protection factor (SPF) and the UV-A label. The SPF indicates how well the cream protects against UV-B rays, while the UV-A label indicates the protective effect against UV-A rays.
• To minimize the risk of skin cancer, it is important to use the sun cream regularly and generously and reapply if necessary. Remember that sun cream alone is not enough to protect you from skin cancer. Also wear protective clothing, avoid the midday sun and seek shade regularly.
• Conclusion: Sunburn is not the only trigger for skin cancer. UV-A rays, which do not cause sunburn, are also involved in the development of skin cancer. It is therefore important, sun creams with a balanced protection against UV-A and UV-B rays and to take other additional measures to protect the skin. Research has clearly shown that this holistic approach is crucial to reducing the risk of skin cancer.

The eighth myth - a thick layer helps more
