Science & Benefits

Polyhydroxystearic Acid is a polyester used as a high-performance dispersing agent. It is specifically used to coat mineral UV filters (Zinc/Titanium), allowing for a high load of pigment without clumping. It is zero-comedogenic. It is a 'bulletproof' choice for acne-safe mineral sunscreens, as it ensures an even, transparent layer of protection that doesn't settle into or clog pores.
