Vitamin D is very important for our health, although we all know that moderation is necessary in everything. During self-isolation, when you are exposed to the sun's rays during your free time (of course! - before 11 am - after 5 pm) or later, when everything is back to its place, do not forget to use sunscreen (in any season and weather). This will prevent premature aging, wrinkles, blemishes, pigmentation and other more serious effects/manifestations. Importantly, it will not interfere with the intake of nitrite and vitamin D.

There are many brands, types, SPF filters and other features of sunscreens on the market. How to choose it according to our skin type and needs? Let's follow step by step:

What is UVA UVB? – UVB are ultraviolet rays that penetrate the dermis layer of the skin, irritating it, resulting in redness and burning. In the long term, this can turn into spots, cracks. As for UVA rays, they penetrate even deeper layers and affect the DNA of dermis cells. As a result, we get hyperpigmentation, premature skin aging and unevenness. The effects of UVA damage may not be immediately visible, but they will definitely show up in the long run.

What is SPF? - Encoded as sun protection factor. It can be found with different indicators of 30, 50, 80 and others. how to choose The higher the rate, the more protection? For example, SPF50 filters 98% of UVB rays, while SPF20 filters 95%. Therefore, the SPF indicator is not insignificant, although it is not decisive. It is more important to use it correctly. How long does the product last after application? To calculate this, we need a little arithmetic - the time until your skin (depending on type/color) burns without protection (very white/light skin 5-10 min, medium/wheat 10-15 min, dark color/brown/black 15-20 min +/- 2-3 min) multiply by the SPF indicator. For example - if we apply SPF 50 on very white/light colored skin, which begins to burn after more than 10 minutes without sun protection, we will get 500 minutes, that is, the product will protect us for about 8 hours after application (if, of course, during this period we will not be in contact with water or anything near a surface that will remove the product (e.g. at sea every time you go in and out of the water you have to reapply).

There are chemical and physical (mineral) sunscreen products. It is logical, the main difference between them - chemical contains chemical (eg: oxybenzone, octocrylene avobenzone, etc.), and physical contains natural ingredients (eg: zinc, titanium oxide). Protective creams of chemical composition absorb the UV rays contained in the skin layer, which is then expressed by the warmth of the skin surface, and thus the layers are released. As a rule, chemical preservatives are lighter in consistency, easily distributed and absorbed by the skin. It is considered that due to its light texture, it coexists better with makeup. Be aware that chemical sunscreens may irritate sensitive skin. When it comes to physical sunscreens, one of their main characteristics is to leave the skin white, which is a manifestation of the ingredients. These active minerals fix on the surface of the skin and reflect/reflect UV rays. Physical sunscreens have a thicker consistency, work instantly after application, and are highly recommended for sensitive and fair-toned skin.

Note – the SPF filter that your cosmetics (foundation, powder, etc.) have is not enough, because the main factor is the concentration of the sun protection factor, which you need to apply a certain amount of product to get (for the eyes - 1/4 teaspoon, about 1.2 grams) . Imagine how many "pumps" 1/4 teaspoon of toner is. It will be quite difficult to distribute this amount of product on your face. Therefore, do not rely solely on the SPF protection of cosmetic products.

As for the sequence, you apply the sunscreen after the care procedures (moisturizer). If you also wear make-up, wait 4-5 minutes for it to absorb well and then start using the products.
