Science
Mechanism of Action
This extract exerts its effects through a rich profile of phenolic compounds, vitamins A and C, and carotenoids, acting primarily as a powerful antioxidant to neutralize free radicals and mitigate environmental damage. It supports skin health by inhibiting enzymes like tyrosinase, elastase, and collagenase, which contribute to hyperpigmentation, loss of elasticity, and wrinkles, respectively. Additionally, it offers anti-inflammatory, soothing, and photo-protective benefits, reduces sebum production and pore visibility, and aids in hydration and nourishment.
