Sun protection factors and why you need to protect yourself from them
According to the results of the survey, for the majority of Russian women, the purchase of sunscreen comes down to buying the first cans that come across in duty-free. Which, of course, is very frivolous and irresponsible. After all, the sun is the biggest enemy of skin youth. “Make sure that your sunscreen is a combination, that is, it contains physical and chemical UVA / UVB protection filters,” recommends Olga Zabnenkova, Olay dermatologist. “Sunscreen should also include restorative components: antioxidants, aloe extract, chamomile, vitamins E and B5, allantoin, bisabolol.

Apply the product 20 minutes before going outside. And we must remember: even if your skin is already chocolate-colored, it still needs sunscreen, even with the lowest degree of protection.
