Science

Mechanism of Action

CORN STARCH MODIFIED operates by physically absorbing superfluous oil and moisture from the skin's surface, thereby diminishing a greasy sensation and contributing to a matte complexion. Its anti-caking properties improve formulation stability and facilitate superior product spreadability for uniform application. Acting as a skin conditioning and film-forming agent, it delivers a refined, silky texture and a smooth sensory experience upon contact.
