Science
Mechanism of Action
This extract's efficacy stems from its high concentration of bioactive antioxidants, including Vitamin C, polyphenols, and flavonoids, which efficiently neutralize free radicals, thereby protecting skin from oxidative stress and premature aging. The Vitamin C content specifically supports collagen production, contributing to improved skin firmness and a reduction in fine lines. Its anti-inflammatory properties work to calm irritation and diminish redness. Furthermore, it exhibits antimicrobial and antiseptic actions, which are beneficial for managing acne and congested skin by reducing pore blockages and inhibiting bacterial growth. It also assists in balancing sebum production, providing hydration, stimulating skin regeneration, and improving overall skin radiance and tone.
