Science
Mechanism of Action
This extract functions as a powerful antioxidant, shielding the skin from free radical damage and environmental aggressors, which contributes to preventing premature aging and enhancing skin texture and tone. Its anti-inflammatory action, attributed to compounds like carnosol and carnosic acid, effectively reduces redness and irritation by inhibiting pro-inflammatory mediators such as nitric oxide (NO) and downregulating IL-1β and TNF-α. Furthermore, it exhibits antimicrobial capabilities, assisting in controlling the proliferation of skin microorganisms, alongside offering skin conditioning, toning, and astringent benefits. The extract also helps defend against pollution-induced oxidative damage by inhibiting MMP-9 and may provide a degree of protection from UVB radiation.
