Skin Health Promotion Effects of Natural Beta‐Glucan Derived from Cereals and Microorganisms: A Review

β ‐Glucans are natural cell wall polysaccharides found in yeast, fungi (including mushrooms), some bacteria, seaweeds and cereals. Natural β ‐glucans possess many health promotion effects on human health, such as anti‐tumor, anti‐diabetes, anti‐infection, lowering blood cholesterol and immune‐modulating properties. These effects have been reviewed previously. However, skin health promotion of β ‐glucan derived from cereals and microorganisms has received little attention. This review focuses on antioxidant activity, anti‐wrinkle activity, anti‐ultraviolet light, wound healing, and moisturizing effect and skin permeation absorption of β ‐glucan. Furthermore, applications of β ‐glucan in cosmetics are also discussed. Copyright © 2013 John Wiley & Sons, Ltd.
