Science
Mechanism of Action
Algae Exopolysaccharides operate through several key mechanisms to fortify and rejuvenate the skin. They form a protective film, shielding the skin from external aggressors such as UV radiation, oxidative stress from free radicals, and temperature fluctuations. As potent humectants, EPS attract and bind water, effectively plumping the skin and enhancing hydration. Furthermore, they actively stimulate the production of vital extracellular matrix components like collagen and elastin, leading to improved skin elasticity and a reduction in the appearance of fine lines and wrinkles. Their antioxidant properties involve scavenging reactive oxygen species (ROS) to prevent cellular damage, while anti-inflammatory actions help soothe the skin. EPS also demonstrate capabilities in modulating immune responses, promoting wound healing, and supporting the skin barrier repair through enhanced epithelialization.

Key findings
- 01 Studies indicate Algae Exopolysaccharides can be effectively incorporated into cosmetic cream formulations within a 0.1-10% concentration range.
- 02 Sulfated polysaccharides, a type of EPS, are proposed for skin moisturization at concentrations ranging from 2-60%.
- 03 Native microalgae exopolysaccharides have been shown to inhibit human matrix metalloproteinase-1 (MMP-1) activity by 27%, an enzyme contributing to collagen degradation.
- 04 Depolymerized forms of these polysaccharides have demonstrated an ability to enhance collagen production in human fibroblast cell lines.

Stability
The stability and rheological properties of Algae Exopolysaccharides are influenced by factors like ionic strength (salt) and pH, as these affect the molecular structure. Optimal pH for microalgae cultivation to produce EPS is typically between 6.5 and 8.5. Formulations containing EPS should be sterile or substantially free of endotoxins and/or proteins.
Safety
Safety Profile
While 'Algae Exopolysaccharides' as a broad term has not been specifically reviewed by the CIR Expert Panel and is noted as 'retired' in their database, numerous specific algae-derived ingredients (many containing polysaccharides) have been evaluated. Some have been deemed 'safe in cosmetics in present practices of use and concentration,' while others lacked sufficient data. Generally, the CIR panel considers various polysaccharides non-toxic and safe for cosmetic use, and microalgal EPS are broadly regarded as non-toxic. No specific SCCS or FDA status is available for the general term.
