SPHAGNUM SQUARROSUM EXTRACT

Description

Sphagnum squarrosum extract, derived from a species of peat moss, is an emerging ingredient in skincare formulations. This extract is rich in polysaccharides, particularly sphagnan, which exhibits unique water-retention properties. The high molecular weight of these polysaccharides creates a protective film on the skin, helping to maintain hydration and improve skin barrier function.

The extract contains phenolic compounds, including flavonoids and tannins, which contribute to its antioxidant properties. These components help neutralize free radicals, potentially reducing oxidative stress and supporting skin's natural defense mechanisms against environmental aggressors.

Sphagnum squarrosum extract has demonstrated antimicrobial activity, which may be beneficial in managing acne-prone skin or in preserving cosmetic formulations. Its slight acidity aligns well with the skin's natural pH, potentially supporting the skin's acid mantle.

In skincare products, this ingredient is often used for its moisturizing, soothing, and protective properties. It may help improve skin texture and elasticity, making it suitable for various skin types, including sensitive and mature skin. However, more research is needed to fully elucidate its long-term effects and optimal concentration in skincare formulations.
