Science
Mechanism of Action
This extract operates through several key biological pathways to bolster skin health. It works by increasing the water content of the stratum corneum, thereby enhancing the skin barrier effect and reducing transepidermal water loss (TEWL) via both humectant and occlusive actions. Rich in potent antioxidants such as polyphenols, flavonoids, Vitamin C, and piscidic acid, it effectively neutralizes free radicals, promoting improved skin elasticity and supporting cellular renewal. The extract also possesses anti-inflammatory capabilities, helping to reduce redness, irritation, and discomfort by blocking stress markers. Furthermore, it stimulates cell turnover and boosts collagen and elastin production, contributing to anti-aging benefits and improved skin firmness. It also helps to regulate melanin synthesis by inhibiting tyrosinase activity, which can lead to a skin brightening effect, and offers antimicrobial properties to address concerns like acne while aiding in soothing sunburn and supporting wound healing.
