Science

Mechanism of Action

This ingredient leverages its rich profile of phenolic compounds to neutralize collagen-degrading free radicals, thereby mitigating signs of aging like fine lines. Its potential to inhibit tyrosinase activity helps reduce melanin production, leading to a brighter complexion and diminished dark spots. Furthermore, organic acids facilitate mild cellular turnover, while its astringent properties aid in sebum regulation and pore refinement. It also contributes to skin hydration and barrier support.
