Эффекты от лазерных методик являются выраженными и стойкими. Известно, что после процедур усиливается микроциркуляция кожи, стимулируется обновление кератиноцитов, фибробластов, но мало информации о молекулярной основе действия абляционных лазеров, о механизмах, лежащих в основе формирования новых тканей (различных типов коллагенов, ламинина, сосудов микроциркуляторного русла).</p><sec><title>Цель исследования</title><p>Цель исследования. Формирование детальное понимания механизмов, лежащих в основе регенераторных процессов кожи после абляционного лазерного воздействия.</p></sec><sec><title>Результаты</title><p>Результаты. После абляционного лазерного воздействия значительно увеличивается количество интерлейкина-1α, что приводит к стимуляции образования коллагенов I и III типа, ламинина. Происходит увеличение сосудистого, фибробластного фактора роста, что также способствует стимуляции пролиферации фибробластов, усилению ее кровоснабжения.</p></sec><sec><title>Выводы</title><p>Выводы. На основании полученных данных можно сделать вывод о том, что фракционные фототермолиз способствует улучшению упруго-эластичных свойств кожи, усилению трофики кожи и активации метаболизма кожного покрова. Пролонгация эффектов от однократной процедуры обусловлена активацией и стимуляцией собственных регенераторных ресурсов кожных покровов, что способствует увеличению собственных фибробластов, коллагенов, сосудов микроциркуляторного русла, клеток эпидермиса и дермы.</p></sec></abstract><trans-abstract xml:lang="en"><p>The use of lasers in medical cosmetology today is widespread. The effects of laser techniques are pronounced and persistent. It is known that skin microcirculation increases after the procedures, renewal of keratinocytes and fbroblasts is stimulated, but there is little information about the molecular basis of the action of ablative lasers, about the mechanisms underlying the formation of new tissues (various types of collagens, laminin, vessels of the microvasculature).</p><sec><title>Purpose of the study</title><p>Purpose of the study.

After ablative laser exposure, the amount of interleukin-1α signifcantly increases, which leads to stimulation of the formation of type I and III collagens, laminin. There is an increase in vascular, fbroblast growth factor, which also helps to stimulate the proliferation of fbroblasts, increase its blood supply.</p></sec><sec><title>Conclusions</title><p>Conclusions. Based on the data obtained, it can be concluded that fractional photothermolysis improves the elastic properties of the skin, enhances skin trophism and activates the metabolism of the skin. The prolongation of the effects of a single procedure is due to the activation and stimulation of the skin’s own regenerative resources, which contributes to an increase in its own fbroblasts, collagens, vessels of the microvasculature, cells of the epidermis and dermis.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>лазер</kwd><kwd>коллаген</kwd><kwd>факторы роста</kwd><kwd>интерлейкин-1α</kwd></kwd-group><kwd-group xml:lang="en"><kwd>laser</kwd><kwd>collagen</kwd><kwd>growth factors</kwd><kwd>interleukin-1α</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Васильева Е.С., Коновка Е.П., Орехова Э.М., Кончугова Т.В., Эктова Т.В.
