Science
Mechanism of Action
It entraps active ingredients within its matrix, protecting them and facilitating sustained release through friction and diffusion. Its high surface area also adsorbs excess sebum and perspiration, providing a matte skin finish.
Research
Clinical Evidence
High confidenceN/A
Key findings
- 01 Clinical studies demonstrate that formulations containing this crosspolymer achieve a matte finish lasting six hours or longer by adsorbing up to 10 times its microparticle weight in excess skin oil, even when pre-loaded with actives.
