Science

Mechanism of Action

Hippophae Rhamnoides Kernel Extract operates through multiple biological pathways. Its rich antioxidant profile, encompassing vitamins and polyphenols, actively neutralizes free radicals, thereby protecting skin from oxidative stress and environmental aggressors. Essential fatty acids fortify the skin barrier, reduce transepidermal water loss, and boost hydration by up-regulating aquaporins and hyaluronan synthetases. Furthermore, it modulates inflammatory responses by decreasing histamine release and enhancing PPARs expression, while stimulating collagen synthesis promotes regeneration, wound healing, and improved skin elasticity.
