植物提取物延缓皮肤光老化作用的研究进展

Research Progress on Anti-skin Photoaging of Plant Extracts

摘要:

摘要：紫外线是导致皮肤光老化的主要因素，寻找和开发能够有效防护皮肤老化的天然产物已被广泛重视。本文从紫外线对皮肤的损伤以及光老化发生的机理入手，通过吸收紫外线、抗皮肤光氧化、调节细胞外基质合成与降解、抑制色素沉着、缓解皮肤炎症、调节细胞自噬等多种途径，对不同来源的植物提取物及其特征化合物延缓皮肤光老化的作用进行归纳分析，以期为天然产物在功能性化妆品的开发和应用提供参考。

Abstract:

Abstract: Ultraviolet (UV) radiation is a major cause of skin photoaging. In recent years, the prevention of UV damage to the skin has been valued by the public, and the exploring of the photoaging prevention active substances has become a research hotspot. This article introduces the effect of UV on the skin and the mechanisms of photoaging. Different pathways are reviewed, including UV absorption, anti-oxidation, regulation of extracellular matrix synthesis and decomposition, inhibition of pigmentation, relief of skin inflammation and regulation of autophagy of different plant extracts delay the ageing of the skin light effect, in order to provide reference for the research and application of natural plant photoprotective functional cosmetics.
