Santrauka:

Teorinėje dalyje buvo apžvelgti ir išanalizuoti fotosenstančios odos biocheminiai ir fiziologiniai procesai, aprašytos cheminių šveitiklių ir antioksidantų rūšys, jų poveikis odai. Praktinę darbo dalį sudaro atliktas kokybinis tyrimas – eksperimentas, kurio metu buvo nustatytas cheminių šveitiklių su antioksidantais poveikis, sprendžiant fotosenstančios veido odos problemas.

Description:

Relevance of the research. Photoaging differs from the natural ageing process in that the former is a reversible process. Using contemporary cosmetics and applying special procedures, it is possible to improve the condition of photoaged skin. The most popular products that are used to treat photoaging are chemical peels (Ramos-e-Silva et al., 2013). One of the causes of photoaging is oxidation, the effect of free radicals on an organism. Antioxidants are an important group of pharmacologically active substances, capable of preventing skin damage and ageing of the skin caused by UV radiation (Oresajo et al., 2012). Research objective: to investigate the effect of chemical peels with antioxidants in solving problems of photoaged facial skin. Research tasks: to explain theoretically the biochemical and physiological processes of photoaging of facial skin; to distinguish theoretically the types of chemical peels and antioxidants and their effect on skin; to determine the effect of chemical peels with antioxidants in solving problems of photoaged facial skin. Research methods: Analysis of scientific and professional literature and qualitative research (experiment). Results and conclusions: photoaging of the skin or premature ageing of the skin results from solar UV radiation, but UVA radiation is especially harmful. Chemical peels cause a controlled separation and regeneration of skin layers and moisturise the skin, smooth wrinkles, increase elasticity, decrease pigmentation and dilated capillaries, and improve the structure of the skin. Antioxidants are substances which reduce or eliminate the cellular damage caused by free radicals. After performing a course of procedures using a chemical peel with antioxidants, the moisture parameters of facial skin and its elasticity improved, and keratinisation and pore size decreased. Changes in melanin and wrinkle depth, compared with changes in other parameters, were small. Such a result for the change in melanin could have been affected by the activity of the spring sun and the use of relatively weak protection (SPF 35). The changes in wrinkle depth could have been affected by the relatively high acidity of the peel (pH3), which led to insufficiently deep penetration into the skin and weak regeneration of cells.
