Science
Mechanism of Action
This ingredient operates through several key pathways: its rich composition of caffeine (up to 6%), theobromine, catechins, and tannins stimulates microcirculation by inducing vasoconstriction, thereby diminishing puffiness and dark under-eye circles. It exhibits robust antioxidant capabilities, neutralizing free radicals and inhibiting lipid peroxidation to safeguard collagen integrity and mitigate photoaging effects. Furthermore, it possesses anti-inflammatory properties, modulating cytokine response to soothe erythema and enhance epidermal resilience. Its astringent qualities assist in regulating sebum production, while mild peeling action promotes cell turnover by gently loosening dead skin cells. Additionally, it offers antimicrobial benefits.
