Science
Mechanism of Action
This ingredient operates primarily as an absorbent, effectively binding excess oil on the skin's surface to achieve a mattified finish and diminish the visual prominence of pores without inducing dryness. It also serves as a bulking agent and controls viscosity within formulations. On a cellular level, rice starch and its associated polysaccharides create a protective film on the skin, thereby enhancing hydration and reinforcing the epidermal barrier function, alongside offering soothing relief for irritated skin.
