Science

Parachlorella Kessleri Exopolysaccharides function primarily as humectants, effectively drawing moisture into the skin and retaining it to provide deep hydration. Mechanistically, they are also associated with anti-aging properties, potentially stimulating the skin's natural synthesis of elastin and collagen, fortifying the skin's barrier function, and delivering antioxidant and anti-inflammatory benefits to safeguard skin from environmental stressors.

Key findings

  1. 01 Referenced in concentrations from 0.1% to 10% within cosmetic formulations for skin moisturizing, the reduction of fine lines and wrinkles, inducing skin tightening, decreasing transepidermal water loss, and enhancing skin elasticity. It is important to note that these reported benefits are predominantly cited in patent claims rather than substantiated by independent, specified-concentration clinical studies.

Our Assessment

Insufficient Data

While Parachlorella Kessleri Exopolysaccharides offer a compelling theoretical foundation for moisturizing and anti-aging benefits, further independent, peer-reviewed clinical studies are essential to definitively validate their efficacy and optimal concentrations for precision skincare applications.
