PARACHLORELLA KESSLERI EXOPOLYSACCHARIDES

Description

Parachlorella kessleri exopolysaccharides are innovative bioactive compounds derived from the freshwater microalgae Parachlorella kessleri. These complex polysaccharides are secreted extracellularly by the microalgae and possess remarkable properties beneficial for skincare applications. Rich in uronic acids, sulfated groups, and various monosaccharides, these exopolysaccharides exhibit potent antioxidant, anti-inflammatory, and moisturizing effects on the skin.

Studies have shown that Parachlorella kessleri exopolysaccharides can enhance skin barrier function by promoting the production of key structural proteins and lipids in the stratum corneum. They also demonstrate significant free radical scavenging activity, protecting skin cells from oxidative stress and premature aging. Furthermore, these compounds have been found to stimulate hyaluronic acid synthesis in dermal fibroblasts, contributing to improved skin hydration and elasticity.

In skincare formulations, Parachlorella kessleri exopolysaccharides are typically used at concentrations between 0.1% to 2%. They are compatible with a wide range of cosmetic ingredients and remain stable across various pH levels. Their film-forming properties provide an additional benefit, creating a protective layer on the skin surface that helps retain moisture and enhance the overall efficacy of skincare products.
