Abstract:

Moisturizing is essential for skin care and important to reduce the chances of skin problems. The stratum corneum and dermis, the natural skin moisture barrier, play an important role in hydration and water storage. In addition, moisturizer is used for moisturizing and protecting the skin. Many plant extracts have obvious hydrating and moisturizing effects on skin. This paper briefly introduced the skin moisturizing mechanism and skin moisturizing methods, mainly reviewing the natural moisturizing ingredients of plant extracts in cosmetics, including plant polysaccharides, oil, saponins, flavonoids and polyphenols. The moisturizing mechanism of plant extracts is different according to their composition and structure. Hydrophilic constituents of plant extracts mainly attract and hold water through hydrogen bonding with their hydroxyl groups or phenolic hydroxyl groups, and they can differ in water binding capacity as in their ability to influence the degree of skin hydration; And fatty acids of plant oils will form a thin layer of oil on the skin to prevent water evaporation and keep the skin moisturized. Besides the application as moisturizing ingredients, many plant extracts also show antioxidant and anti-inflammatory activities which have great potential application in cosmetics. Here we review the moisturizing ingredients of plant extracts in detail, in order to provide ideas for the application of plant extracts as natural moisturizers in cosmetics.

Key words: plant extracts, moisturizers, cosmetics
