Santrauka:

Darbe apibūdinamas fotosenėjimas, jį sukeliantys veiksniai, atsiradimo mechanizmas, požymiai, apsisaugojimo būdai, požymių korekcija cheminių šveitiklių pagalba ir cheminių šveitiklių veikimo mechanizmas. Atliktas eksperimentas, kurio metu stebėti fotosenėjimo požymių turinčių odų parametrų pokyčiai prieš ir po cheminių šveitiklių kurso.

Description:

The topic: The effect of chemical peeling in photoaged skin. The problem: What is the effect of chemical peeling in photoaged skin? The object: The effect of chemical peeling in photoaged skin. The aim: To determine the effect of chemical peeling in photoaged skin. Goals: 1. To describe photoaging and the reasons it appears; 2. Theoretically explain the impact of chemical peelings in photoaged skin; 3. To reveal the impact of chemical peelings in photoaged skin. The relevance The topic of photoaged skin is very relevant for the white people because white skin is not adapted to defend itself from the UV radiation as well as the dark skin. The marks of photoaged skin appear faster and are more noticeable in light-skinned people (Chien ir kiti, 2017). Even though the sunscreen with SPF is one of the main protective mechanisms from the UV radiation, not enough people use it regularly. There was a survey done in Lithuania in 2015 where it was found out that only a little bit more than the half of the participants used sunscreen while being in the sun (Kirvaitienė ir kiti, 2015). Photoaging does not appear rapidly. It cumulates, affects skin in the cellular level and appears after a row of years of sun exposure. The cosmetologists are the people who have competence to solve photoaged skin problems and it is one of the most popular treatments nowadays (Les Nouvelles Esthetiques Lietuva, 2014). The mothods of the research and the organization The research took place in Kaunas College, the department of Cosmetology, in 2018 March – May. The aim of this research was to determine the effect of chemical peeling (glycolic acid) in pfotoaged skin. 5 participants with fotoaged skin were selected (age 35-45). They had their skin analyzed 5 times with the “Skin Analyzer Soft Plus” device and chemical peeling performed 5 times. 4 measurements were done every ten days before every peeling procedure and the last measurement – after 2 weeks after the last procedure. Conclusions 1. Photoaging is skin aging induced by UV radiation. It chronically influences the skin and causes damage in cellular level. While UV radiation in affecting skin, free radicals have good conditions to do the damaging themselves, natural cell mechanisms are damaged, skin protection mechanisms start working exaggeratively. The fibers of collagen and elastin are being reorganised, they become stiff, the skin looses its smooth texture, hialuronic acid is being split up, capillaries expand and become visible. The signs of photoaging are: deep early wrinkles, pigmentation, dilated pores, reduced level of skin elasticity and moisture, hiperkeratosis, elastosis. 2. Chemical peelings are one of the most effective ways in fixing the problems of photoaged skin. It is a controlled damage of the skin – when the skin registers the damage in epidermis, signaling molecules give an impuls in the basal layer to work more intense. The distribution of the cells become faster, the synthesis of kolagen, elastin fibers, hialuronic acid become more intense. Chemical peeling work directly to the problems of photoahed skin: it disperses the accumulation of melanin, reduces the deph of wrinkles, induces the elasticity and moisture of the skin, helps to remove accumulated corneocytes, reduce the diameter of the pores. 3. The effect of chemical peeling in photoaged skin is positive. All the signs of photoaged skin became less visible after the experiment ended: the amount of melanin, the diameter of pores, the accumulation of corneocytes and the deph of the wrinkle reduced. The moisture and elasticity of the skin induced. Glycolic acid is a suitable choice for reducing the signs of photoaged skin.
