Algae Oligosaccharides

What is Algae Oligosaccharides?

Algae Oligosaccharides are short-chain sugar molecules derived from brown marine algae, such as Laminaria species, through enzymatic breakdown of algal polysaccharides. These bioactive compounds are commonly incorporated into moisturizers, serums, and creams within skincare formulations. In products, they work by drawing moisture from the environment into the skin's upper layers, enhancing the skin barrier's water retention capacity. Additionally, their film-forming properties help maintain skin suppleness by interacting with skin proteins and lipids, promoting a smoother surface feel. Sourced sustainably from ocean algae, they offer a natural alternative to synthetic humectants, supporting formulations aimed at daily hydration routines without heaviness.
