Trehalose
Description
Trehalose is a naturally occurring disaccharide composed of two glucose molecules linked by an α,α-1,1-glycosidic bond. This unique sugar is found in various organisms, including plants, fungi, and invertebrates, where it serves as a protective agent against environmental stresses. In skincare formulations, trehalose functions as a powerful humectant and moisturizer, attracting and retaining water in the skin.
The molecule's structure enables it to form a gel-like matrix on the skin's surface, creating a protective barrier that helps prevent transepidermal water loss. This property makes trehalose particularly effective in maintaining skin hydration and improving overall skin texture. Additionally, trehalose exhibits antioxidant properties, helping to neutralize free radicals and protect skin cells from oxidative damage.
Research has shown that trehalose can enhance the stability of proteins and lipids in the skin, potentially supporting the skin's natural barrier function. It also demonstrates cryoprotective properties, which may help protect skin cells from damage caused by extreme temperatures. In cosmetic formulations, trehalose is often combined with other hydrating ingredients to create synergistic moisturizing effects. Its non-sticky texture and compatibility with various skin types make it a versatile ingredient in a wide range of skincare products.
