Did you know that the intensity of UV radiation increases by four percent, every three hundred meters altitude? And that these sunscreens can be chemical or mineral? Neither did I, until I attended the lecture of London dermatologist Sam Bunting, a true expert in the field. So, dear ones, do not repeatedly lubricate with cream with protection factor 15, because more layers do not mean increased protection. For other myths and truths about protecting your skin from the sun in the mountains, read on.
"It's sufficient to smear yourself once, in the morning." You should anoint yourself with a sunscreen every two hours, regardless of FPS value. The only difference between factor 70 and factor 30 is the number of rays whose access to your skin is blocked. The duration of the action is, however, two hours, in both cases. The amount of cream is also important. The rules say that for the face and neckline, you need 5 ml of cream (ie 22 mg per square centimeter). It is always applied to the cleansed skin, over the day cream.
"Only UVB rays are harmful."
If the UVB radiation that reaches the earth is medium waves, which penetrate only the upper layers of the epidermis, the UVA rays, with large wavelengths, penetrate into the subcutaneous tissues. It is precisely this type of radiation that can pass through the clouds or through the glass. In addition, solar radiation is composed of 90% of UVA rays, only 10% being UVB and UVC rays. UVB rays cause acute skin reactions, such as redness and synthesis of important vitamin D (one hour a week is sufficient). However, long-term reactions that cause carcinoma or, in other words, skin cancer are dangerous. UVA rays especially have delayed effects on skin cells, such as conditions and accelerated aging.
"Sunscreen is only used on the beach."
The intensity of the UV radiation depends on the altitude, the reflection on the surface (sand or snow) and even on the geographical location. It has been proven that as the altitude increases, the intensity of the sun's rays also increases, by 4% every 300 meters. It means that at 1,500 m altitude, the sun is 20% more intense than in Croatia, at sea. Even if we are protected by a thick layer of clothing, through which the rays do not penetrate, we must not underestimate the protection of the face, lips, and eyes. You will surely be attracted to the Piz Buin mountain sun cosmetics, which provide complete care for the skin affected by the harsh wind and the alpine sun.
"It does not matter which skin care sunscreen you buy, as long as it has a suitably high defense factor."
You have to choose the specific sunscreen cream, depending on the type of skin and the type of activity expected. In the mountain, you do not need a waterproof cream, as in the sea, but instead, you need protection from the wind and frost. As a general rule, oily skin will respond better to a tanning lotion than to oil or cream. On the other hand, the lighter texture of a tanning lotion corresponds to a lower FPS. An exception to this rule is Anthelios AC, a face-protecting liquid, SPF 30, from La Roche-Posay brand. Nowadays there are sunscreen creams specially designed for wrinkled, atopic or extremely sensitive skin.
"The sunscreens are hard absorbed and leave white traces."
Sunscreens, that is, sun protection can be classified according to how they protect against UV radiation. Chemical sunscreens act on the principle of transforming solar radiation into heat, which is then released from the skin. Physical or mineral sunscreens reflect or scatter the sun's rays. Both types have advantages and disadvantages, so for maximum protection, combination creams are recommended.
Chemical sunscreens often contain harmful substances, such as oxybenzone, Ethylhexyl, and benzophenone, which break down into free radicals and carcinogens, which are dangerous to inhalation. It is not recommended for children or people with sensitive skin. However, they are more cosmetically suitable, because they leave no white or greasy marks, they can serve as a primer and mattify the complexion. A quality chemical blocker is, for example, the Elisabeth Arden Eight Hour Cream balm with SPF 50. Mineral creams, ie physical, sunscreen are suitable for sensitive skin and are generally more skin-friendly, but a generous layer is required to act properly. Therefore, it forms a thick white film and spreads hard on the skin. In addition, they are easy to remove, which is why they need to be reapplied regularly. When choosing a sunscreen mineral cream, we are interested in the highest percentage of zinc oxide and also the content of non-nano particles (microparticles), which cannot penetrate the skin. Nano-particles and the effect of their skin absorption on the body have not been sufficiently investigated.
Morning skincare in the mountains
Step no. 1: Previously cleansed and toned skin, apply the preferred serum (ideally, with the addition of vitamin C) and a moisturizing day cream. The sunscreen is applied to the makeup base and allowed to dry. My favorite is Eight Hour Cream, with SPF 50, from Elisabeth Arden.
Step no. 2: Apply makeup, with an SPF of at least 30. It is important that the makeup is also water-resistant. It is true that you will not swim in the sea, but most likely you will sweat. You can try Sun Foundation SPF 30, from Shiseido.
Step no. 3: Over makeup uses a mineral powder with sun protection. Thus, you apply a very effective physical blocker and, at the same time, smooth the complexion at the end.
