Science
Mechanism of Action
This extract acts as a powerful antioxidant, neutralizing free radicals to prevent oxidative stress and signs of aging. It reduces inflammation, effectively soothing irritated skin and minimizing redness. Key compounds like gallic acid and catechin synergistically inhibit tyrosinase activity, aiding in the evening of skin tone and reduction of pigmentation. Additionally, it helps control skin oil secretion, acts as an astringent to tighten pores, promotes skin regeneration, and possesses antiseptic and detoxifying properties.
