Marine Exopolysaccharide
INCI / Active Ingredient Category: Marine Exopolysaccharides
Source: Biotechnologically derived from a planktonic microorganism
Applications: Skin care, anti-aging, moisturizing, sensitive & blemish-prone skin
What is a marine exopolysaccharide?
A marine exopolysaccharide is a biotechnologically produced, high-purity sugar complex secreted by a planktonic microorganism. The active ingredient used here originates from a unique marine ecosystem off the coast of Brittany (Aber-Benoît, France) and has no terrestrial counterpart.
Chemically, the exopolysaccharide consists, among other things, of galactose and N-acetylglucosamine—a natural building block of the skin that plays a central role in the formation of glycosaminoglycans (GAGs). These are essential for water retention and the elasticity of the dermis.
Effect on the Skin
Marine exopolysaccharide has a holistic effect on skin health and supports three key skin functions:
1. Strengthening the skin barrier
The active ingredient promotes the differentiation of keratinocytes and accelerates cell renewal. This strengthens the skin’s structure, reduces rough patches, and leaves the skin looking smoother and more even.
2. Support for the skin’s natural defenses
Marine exopolysaccharide activates the skin’s innate immune defense while simultaneously reducing pro-inflammatory mediators.
The result:
- reduced skin reactivity
- less redness
- inhibits the growth of bacteria that stress the skin (e.g., in cases of blemished skin)
3. Improved moisture retention (“Hydra-Memory”)
The active ingredient stimulates the synthesis of hyaluronic acid in the dermis, thereby strengthening the skin’s natural moisture reserves. The skin regains its ability to rehydrate itself after exposure to dry conditions—for long-lasting, plump, hydrated skin.
- antioxidant
- free-radical-scavenging
- photoprotective
- soothing
As a result, the extract protects the skin from oxidative stress and prevents photoaging (light-induced skin aging).
