polysaccharides

Description

Polysaccharides are complex carbohydrates composed of long chains of monosaccharide units linked by glycosidic bonds. In skincare, these naturally occurring molecules play a crucial role in maintaining skin hydration, improving texture, and supporting the skin's barrier function. Derived from various sources such as plants, algae, and even bacterial fermentation, polysaccharides exhibit diverse properties beneficial to skin health.

These versatile ingredients function as humectants, drawing moisture to the skin and helping to retain hydration. They also form a protective film on the skin's surface, reducing transepidermal water loss and enhancing overall skin smoothness. Some polysaccharides, like hyaluronic acid and beta-glucans, have shown remarkable anti-aging properties by stimulating collagen production and promoting cellular renewal.

In skincare formulations, polysaccharides are valued for their ability to improve product texture and stability. They often serve as natural thickeners and emulsion stabilizers, contributing to a pleasant sensory experience. Additionally, certain polysaccharides possess anti-inflammatory and antioxidant properties, offering protection against environmental stressors and supporting the skin's natural healing processes.
