HYDROLYZED ALGAE EXTRACT.

Valuable / SKIN CONDITIONING

Hydrolyzed Algae Extract is a marine-derived ingredient celebrated for its multi-functional benefits, primarily acting as a potent hydrator and protective agent. It significantly enhances skin moisture levels, comparable to hyaluronic acid, while offering antioxidant defense against environmental stressors. This extract also supports skin revitalization, barrier function, and contributes to a brighter, more even complexion.

Science

Mechanism of Action

This extract operates on multiple levels to benefit the skin. It forms a protective barrier through sulphated phycocolloids binding to skin proteins and enhances the Natural Moisturizing Factor (NMF) via osmoregulating molecules, thereby creating a substantial water reservoir within the epidermal layers. Beyond hydration, it stimulates blood circulation, boosts cell renewal, and delivers revitalizing and re-mineralizing effects. As a rich source of antioxidants, it actively defends the skin from environmental damage and mitigates signs of aging by inhibiting collagen-degrading enzymes. Its natural vitamin C content aids in brightening the skin and improving tone by reducing melanin production. Furthermore, it possesses anti-inflammatory properties and fortifies the skin's natural barrier, decreasing susceptibility to irritants, with polysaccharides contributing to a moisturizing film on the skin surface.

Key findings

  1. 01 Demonstrated increased skin hydration after both short-term (under one hour) and long-term (one week) application, with effects comparable to a 0.5% hyaluronic acid cream.
  2. 02 Significantly boosted moisture levels, doubling them immediately post-application and sustaining high levels for over three hours. After eight days, skin moisture was more than 20% higher than controls pre-application and amplified the moisturizing effect of a placebo by 50% post-application.
