Antioxidant Anti-inflammatory Acne Mitigation Moisturizing Skin Barrier Support Collagen Stimulation Gentle Exfoliation Antibacterial Skin Conditioning

Science

Mechanism of Action

This extract operates through a synergistic blend of components, including polyphenols, vitamins C and E, and alpha-linolenic acid. These potent antioxidants neutralize free radicals, offering robust protection against environmental damage. Its anti-inflammatory action, demonstrated by reduced pro-inflammatory cytokines like IL-1β and TNF-α, helps calm skin. For acne concerns, it mitigates development by inhibiting 5α-reductase and P. acnes lipase. Furthermore, it supports skin barrier function for enhanced hydration, stimulates collagen synthesis for improved elasticity, and provides gentle exfoliation, contributing to a smoother, more refined complexion.
