SPF protection

the skin - 10 minutes of sun exposure without cream equals 300 minutes of sunburn with the right SPF30 lotion applied. This is why the sunscreen needs to be applied evenly and the cream needs to be renewed regularly.

The photo above clearly shows the damage caused by the sun to the skin. The left and right halves of the 69-year-old truck driver's face are markedly different. If the left side of the face was regularly exposed to the destructive effects of the sun, then the right side was in the shade of the cockpit. At the same time, protection from the sun is necessary both directly for the skin of the face, and for the lips and eyes - remember that ultraviolet rays can easily damage the retina. In this case, you will need either quality sunglasses or contact lenses with SPF.

undesirable consequences: -photoaging; -the appearance of allergic dermatitis; -the appearance of sunburn; -development of malignant changes. Exposed areas of the skin, mainly the face, need to be protected from ultraviolet radiation all year round. During the day, use a cream with SPF, which will prevent photoaging of the skin: dryness, the appearance of premature wrinkles and age spots, a decrease in firmness and elasticity, rosacea. According to cosmetologists, in 70% of cases, the skin ages precisely due to exposure to ultraviolet radiation. This is due to the fact that ultraviolet light penetrates into the dermis (deep layer of the skin) and promotes the formation of free radicals, which have a destructive effect on collagen fibers.

several factors must be considered: -your phototype; -the condition of your skin (in case of hypersensitivity, inflammation, moles and pigmentation, as well as after peels and aggressive cosmetic procedures, an SPF protection of at least 30 is required); -age (in people after 35 years of age, the skin itself loses its natural protection, therefore, with age, sunscreen should be chosen with a large amount of SPF); -UV index in your area; -time spend outdoors.

UVB radiation, which provokes sunburn, is considered to be the numbers indicated next to the abbreviation SPF: SPF 10 blocks less than 90% of UVB rays; SPF 15 - 93%; SPF 30 - 97%; SPF 50 (+) - 98%; SPF 100 is filtered to 99%. There are 2 types of filters: physical and chemical. The physical ones create a kind of protective shield on the skin, which reflects the rays that hit it, and the chemical ones take the flow of rays onto themselves, absorbing the radiation before it harms the skin.
