Cosmetologist warned about rapid skin aging due to the sun

Up to 90% of visible age-related skin changes are caused not by natural aging, but by the damaging effects of ultraviolet radiation. Unlike natural aging, which manifests itself after 40-50 years, signs of photoaging can be seen already in 30-year-olds, especially those who abuse tanning. Elizaveta Shukhman, cosmetologist at JSC "Medicine" (Academician Roitberg Clinic), told Izvestia about this on May 22.

She explained that photoaging is a complex biological process in which UV rays damage DNA cells, destroy collagen fibers and elastin, depriving the skin of elasticity and freshness.

"The mechanism of photoaging is well studied: ultraviolet type A (UVA), penetrating into the deep layers of the skin, causes the formation of free radicals. These aggressive molecules trigger a chain reaction of oxidative stress, damaging cell membranes and important proteins," Shukhman said.

She added: externally, it manifests itself as premature wrinkles, hyperpigmentation, vascular asterisks and loss of a clear oval face. It is characteristic that the changes primarily appear in open areas — on the face, neck, decollete area and arms, whereas skin protected by clothing can keep youth much longer.

Interestingly, dark—skinned skin ages more slowly due to the high content of melanin, a natural filter that blocks up to 50% of harmful radiation. However, no phototype is completely immune from photoaging. Effective prevention requires an integrated approach: daily use of creams with SPF-30+, even in cloudy weather (UVA rays penetrate clouds); the use of antioxidants (vitamins C and E, resveratrol); professional cosmetic procedures.

"Modern sunscreens use two types of filters: physical (mineral, based on zinc oxide or titanium dioxide) create a reflective barrier on the skin, while chemical ones, like avobenzone or octocrylene, absorb ultraviolet light, converting it into safe heat," the expert noted.

The former, she says, can leave a white plaque and clog pores, while the latter can cause allergic reactions in sensitive skin. Hybrid formulas combining the advantages of both types of protection are the ideal solution. It is important to remember that even the most perfect cream requires updating every two hours and after bathing.

Earlier, on May 8, Zarema Omarova, a dermatologist, cosmetologist, and co-owner of Dr. Omarov's clinic network, told Izvestia that the skin requires preparation for the sunny season. According to her, uncontrolled exposure to the sun is especially dangerous for owners of the first and second skin types, people with a tendency to hyperpigmentation, as well as in the presence of a large number of nevi — moles.
