Abstract: Aged skin, featured with dryness and wrinkles, has received mounting attention due to its adverse influences on beauty. β-Sitosterol and vermicularin are two common active ingredients of Thamnolia vermicularis (Sw.) Ach., a traditional Chinese medicine, of which the anti-aging effect has been discovered. Their protective performance against skin aging was assayed by co-culturing with skin cells in this work. Results showed that β-sitosterol promoted the biosynthesis of hyaluronic acid by increasing the expression of hyaluronic acid synthases in fibroblasts and enhanced the expression of skin barrier functional proteins including aquaporin 3, loricrin, filaggrin and involucrin in keratinocytes, which conduced to the moisture retention within skin.... |

ABSTRACT The human skin aging process is a complex mechanism that can be induced both by intrinsic and extrinsic factors. Observations include a decrease in the biosynthetic and proliferative capacity of cells, increased expression of matrix metalloproteinases, reduction in collagen type I expression, and the progressive disappearance of elastic tissue in the papillary dermis. L-arginine, the substrate of nitric oxide synthesis, is involved in angiogenesis and cell proliferation, as well as an indirect precursor of collagen synthesis via the proline pathway. The aim of this study was to examine the tensile strength, histology, and immunohistochemistry of female and male mice skin receiving different concentrations of topically applied L-arginine, in order... |
