Science
Mechanism of Action
This ingredient physically exfoliates, smoothing skin texture by removing superficial dead cells. Beyond its abrasive action, it conditions the skin through essential fatty acids (linoleic, linolenic, oleic) crucial for maintaining the skin's barrier function and hydration. Carotenoids, precursors to Vitamin A, support cell stimulation and renewal, contributing to anti-aging effects. Vitamin E provides antioxidant protection, and its anti-inflammatory properties are attributed to COX-1 and COX-2 inhibition, promoting overall skin health and elasticity.
