Sun care
Summer, sun, SolvineaMed – reliable protection for every skin type
DERMASENCE sun protection for every skin type
Reliable protection on sunny days
Sunshine is good for you – it lifts your mood and supports important processes in the body. At the same time, UV radiation poses one of the greatest challenges to skin health.
Results from our nationally representative survey* show: Only about 52 % of people feel sufficiently informed about sun protection. Comprehensive UV protection is one of the most important measures to protect the skin from sun-related stress. Your individual skin type, the appropriate sun protection factor, and correct application are key factors.
Here you will learn why UV protection is so important, how to best protect your skin, and which products best support your needs.

- UV-A radiation is long-wave (320-400 nm) and can penetrate into deeper skin layers, including the dermis.
- It is responsible for photoaging (light-induced skin ageing) by damaging the collagen structure. Remember: A stands for ageing, meaning skin ageing.
- It remains relatively constant throughout the year, even on cloudy days. It can even pass through window glass. This is why year-round protection against UV-A radiation is recommended.
- UV-B radiation is medium-wave (280-320 nm) and primarily affects the epidermis, the outer layer of the skin.
- It triggers the skin’s natural protective mechanisms, such as thickening of the top skin layer and tanning. Another helpful reminder: B stands for burning or sunburn.
- It causes redness (erythema).
- It can damage cell nuclei.
- It is responsible for the synthesis of vitamin D.
The most significant damage caused by UV radiation affects our DNA: UV-B rays, in particular, can directly alter DNA and are the main cause of sunburn and skin cancer. UV-A rays penetrate deeper into the skin and indirectly contribute to DNA damage through oxidative stress. During this process, free radicals form that can damage cell components – including DNA. If such damage is not sufficiently prevented, it can accumulate over time, increasing the risk of skin cancer and accelerating the natural ageing of the skin.
Comprehensive protection against all relevant components of solar radiation is therefore essential. DERMASENCE SolvineaMed sun protection products provide reliable DNA and cell protection with the DNA Shield, a combination of broad-spectrum UV-A/UV-B protection and antioxidants such as ectoin and vitamin E.
Take your skin type into account
Your skin’s sensitivity to UV radiation depends, among other factors, on your skin type
Apply a sufficient amount of sunscreen
Only a sufficient amount of sunscreen ensures that the stated sun protection factor is actually achieved. Find out here how much sunscreen you should apply
Regular reapplication is important
Sunscreen must be reapplied regularly to maintain protection, especially after swimming, drying off, or heavy sweating – even when using “water-resistant” products
Clothing and accessories
Wearing sturdy clothing, a sun hat, and sunglasses provides additional protection against UV radiation
Avoid the midday sun
Especially when the UV index is high, avoid prolonged exposure to direct sunlight
Make good use of shade
Shade (for example from concrete structures) reduces UV exposure but does not offer complete protection from the sun
Each skin type reacts differently to sunlight. Skin type determines how quickly the skin reacts to UV radiation and how long it can remain in the sun without protection before redness develops. This process is known as natural protection time. When sunscreen products are applied correctly, they can extend the skin’s natural protection time. However, this protection time cannot be extended indefinitely: Regular reapplication of sunscreen does not further increase the extended natural protection time, but only helps to maintain it. Lighter skin types tend to be more sensitive to UV radiation than darker skin types. However, even very dark skin types are not immune to UV-related skin damage such as sunburn or skin cancer.
According to a widely used calculation, the sun protection time can be accurately determined by multiplying the Fitzpatrick skin type by the sun protection factor. For example, in a person with Fitzpatrick skin type III and a natural protection time of 15 minutes, the calculated protection time with sun protection factor 30 is 450 minutes (7.5 hours). However, this calculation is now considered outdated, as it suggests an unrealistically long duration of protection and may give a false sense of security. We therefore strongly advise against applying this calculation in everyday life.
How much sunscreen should I use?
The stated sun protection factor can only be achieved if a sufficient amount of sunscreen is applied. As a general rule, 2 mg per cm2 of skin should be applied – this corresponds (depending on body size) to about 40 g for the entire body.
Rule of thumb for applying the correct amount:
- 1 teaspoon for the face
- 3-4 heaped tablespoons for the body
Our nationwide representative survey on sun protection in Germany* shows: 57 % of respondents apply less than the recommended amount to their face and therefore do not obtain full protection.
Sunscreen should be applied approximately 10 minutes before sun exposure. To maintain protection, reapply the sunscreen regularly – especially after swimming, drying off, or heavy sweating.
SolvineaMed sun protection meets specific requirements for dermatologically sound sun protection and is recommended by leading dermatologists.
Very pleasant and effective to use, and practical to handle.
An appealing formulation with an excellent skin feel.
Scalp liquid: 5 stars. Facial fluid: 5 stars, prominent tube.
Sensitive or allergy-prone skin may react particularly strongly to UV radiation. This makes it all the more important to use a sunscreen with a high sun protection factor and a low-irritant formulation that is very well tolerated and feels pleasant on the skin. DERMASENCE SolvineaMed Sun protection gel cream SPF 50+ is suitable for sensitive and allergy-prone skin. The light, oil-free sunscreen is especially recommended for individuals prone to (sun) allergies and Mallorca acne. It is also very suitable for people with rosacea, as it protects sensitive skin from UV radiation – one of the most important trigger factors for rosacea.
For children, the following applies: The skin is particularly sensitive, and consistent UV protection is essential. This includes shade, protective clothing, headwear, and reliable sun protection. For everyday life and shared outdoor activities, DERMASENCE SolvineaMed Sun protection lotion SPF 50+ is the ideal solution for sun protection for the whole family.
Are water-resistant sunscreens really water-resistant?
The term “water-resistant” can sometimes be misleading. Many people assume that water-resistant sunscreens provide complete and lasting protection, even when exposed to water. Our sun protection survey* shows that only 38 % of respondents are aware that water-resistant sun protection products are not 100 % waterproof. In fact, a sun protection product can be described as water-resistant if a standardised test procedure shows that at least 50 % of the original protection remains after 40 minutes in water.
Water-resistant UV protection with SolvineaMed
In accordance with DIN EN ISO 16217:2022-02 and the COLIPA Guidelines 2005, SolvineaMed sun protection products offer water-resistant protection that is reduced by no more than 50% after 40 minutes in water. Reapplication is important to maintain the protective effect as consistently as possible – especially after swimming, drying off, or heavy sweating.
Whether jogging, beach volleyball or an extended round of tennis – outdoor sports often mean intense UV exposure. Sweating and physical activity place additional strain on sunscreen. DERMASENCE SolvineaMed sun protection products offer sweat-resistant sun protection with a high sun protection factor that is easy to apply and feels pleasant on the skin.
In addition, sunscreen should be reapplied generously and regularly to all exposed areas of skin – including often overlooked areas such as the neck, ears, and scalp. This is especially important when hair is thinning, as the scalp is often strongly exposed to the sun. Sunburn on the scalp increases the risk of developing actinic keratoses, a precursor to white skin cancer. The ultra-light DERMASENCE SolvineaMed Sun protection liquid AK SPF 50+ provides effective protection.
In winter sports too, the risk of UV exposure is often underestimated: UV exposure is often higher in the mountains, and snow reflects UV radiation. When skiing, snowboarding or winter hiking, a facial sunscreen that feels light on the skin is therefore recommended – for example a light facial fluid such as DERMASENCE Sun protection facial fluid SPF 50+.
Sun protection on cloudy days?
Yes, it's true: UV radiation can reach the skin even on cloudy days. UV-A rays, in particular, remain almost constant throughout the year – regardless of weather or season – and can even pass through window glass. Daily UV protection is therefore recommended. However, our nationwide representative survey* on sun protection shows that only one in three people continue to use sun protection in cloudy weather. Those who spend a lot of time outdoors in their daily lives – for example, on their way to work, going for walks, or during short outdoor activities – should include a day cream with SPF in their daily routine, especially for the face.
DERMASENCE sun protection – Formulated to be ocean-friendly
Recent studies suggest that sunscreens may cause significant damage to coral reefs. This appears to be due to commonly used UV filters that are often found in sunscreen products. Oxybenzone (benzophenone-3) and octinoxate (ethylhexyl methoxycinnamate) protect the skin from the harmful effects of UV radiation. Unfortunately, both active ingredients are now also suspected of contributing to harmful coral bleaching, which can result in the death of entire coral reefs. In doing so, they may endanger entire ecosystems and ultimately also have an impact on climate change.
All DERMASENCE sun protection products are free from oxybenzone and octinoxate.
Refreshing care for dry skin during the summer
Even with high UV protection, sunny and warm days can put strain on the skin. They can dehydrate the skin and increase oxidative stress. With appropriate medical skincare, the effects of dry summer days and strong UV radiation can be effectively counteracted. We recommend refreshing formulations with active ingredients that deeply hydrate the skin.
Our after-sun recommendation for body and face: DERMASENCE Aloe Vera Active Gel provides intensive moisture for skin that has been particularly stressed by the sun. The high proportion of natural extracts from aloe vera leaves helps stimulate the skin’s own repair processes. The cooling effect feels particularly refreshing on application – especially when the gel is stored in the refrigerator! Leave the mask on for around 10-15 minutes before removing it with lukewarm water or a damp towel.
