What it is
Pholiota Microspora Polysaccharides are sugar polymers extracted from the nameko mushroom (Pholiota microspora), a species cultivated in East Asia. These polysaccharides are water-binding and can form a light film on the skin, contributing humectant and conditioning effects and a smooth feel. In sunscreens they are used as a supporting moisturizing component rather than as a UV filter.
Safety & warnings
Mushroom-derived polysaccharides are large, water-soluble molecules that are generally well tolerated and non-comedogenic. Sensitivity is uncommon but possible, and overall tolerability also depends on the carrier and preservative system.
Origin & sourcing
Natural, derived from the fruiting body of the nameko mushroom (Pholiota microspora), typically isolated as a water-soluble polysaccharide fraction.
