Science

Mechanism of Action

This extract functions as a potent antioxidant, effectively neutralizing reactive oxygen species (ROS) and limiting the formation of advanced glycation end products (AGEs), thereby shielding skin cells from oxidative stress. Its anti-inflammatory capabilities soothe irritation, while specific constituents like verbascoside contribute antimicrobial and photoprotective benefits. The extract deeply moisturizes, aids in collagen synthesis, strengthens the skin's protective barrier, and fosters skin regeneration. Furthermore, it exhibits anti-tyrosinase activity, significantly inhibiting melanin production for skin brightening, and may improve microcirculation while demonstrating immunomodulatory effects.
