The sun and solar radiation are the main cause of photoaging of the skin and the appearance of neoplastic changes. Protection against them will be provided by a good, proven sunscreen.
The culprit is bothUVA radiation , which reaches the level of the dermis, causing unfavorable changes in fibroblasts, destroying the collagen and elastin fibers they produce, as well asUVB rayswhich act shallower, mainly at the level of the epidermis, causing damage to the DNA of cells.
Only a sunscreen will protect your skin
The effects of photoaging of the skin are not immediately visible - if it were so, many people would protect themselves from the sun much more carefully, all year round. Remember that the highest intensity of UVB radiation is in spring and summer, around noon, while we are exposed to UVA rays equally at any time of the year, from sunrise to sunset, they are not blocked by clouds, windows or clothing. Only a cosmetic with a sufficiently high filter can cover the skin.
In the city, a 15-20 filter will provide sufficient protection, but on the beach it is not enough. When choosing a cosmetic, it is best to follow the phototype, because it is the easiest way to assess sensitivity to the sun; in general - the lighter the skin, hair and eyes, the higher the filter should be. The moles should be protected with particular care, preferably by using blockers, i.e. preparations with a 50+ filter that retain over 90% of the skin. UVB rays and at least 50 percent. UVA.
Don't save on cream
Besides, you cannot save the cosmetic. You need to apply it to the whole body at least 30 ml and repeat the application every 3-4 hours. It is also worth remembering that despite the best protection, the sun dries the skin and causes the so-called. oxidative stress, i.e. releases destructive free radicals in it. Therefore, after sunbathing, you need to use cosmetics that will repair or minimize the damage - restore proper skin hydration, neutralize free radicals, soothe irritations.
