RESUMEN
Skin aging is one of the topical issues in modern gerontocosmetology. Application of cosmetic products with short peptides is a promising measure for retardation of skin aging. This research is aimed at investigation of KE (Lys-Glu, Vilon) dipeptide influence on the expression of markers of aging in human skin fibroblasts in vitro. Collagen type I and sirtuin-6 expression in «young¼ and «old¼ skin cell fibroblasts cultures was studied using immunofluorescence confocal microscopy method. The areas of expression of collagen type I and sirtuin-6 are known to decrease in skin fibroblasts with aging by 3,5 and 3,6 times accordingly. KE dipeptide increases collagen type I expression area in «old¼ skin fibroblasts cultures by 83%. KE dipeptide increases expression area of sirtuin-6 in «young¼ and «old¼ skin fibroblasts cultures by 1,6 and 2,6 times correspondingly. Thus, KE dipeptide promotes functional activity of skin fibroblasts and inhibits their aging.
