SEQUOIA SEMPERVIRENS LEAF CELL EXTRACT.

This extract acts as a potent anti-aging agent by directly reducing the appearance of deep, superficial, and crow's feet wrinkles. It achieves this by densifying the dermis and stimulating the biosynthesis of critical structural components, notably collagen and proteoglycans, which enhance skin firmness. Its moisturizing capabilities are attributed to an increased capacity for water retention within the epidermis and a strengthened cutaneous barrier, consequently minimizing transepidermal water loss. Furthermore, the extract exhibits significant antioxidant properties, neutralizing reactive oxygen species (free radicals) and elevating the activity of endogenous antioxidant enzymes like SOD and catalase. It also demonstrates a soothing effect by decreasing the presence of three specific inflammation mediators. Components such as shikimic acid may promote skin repair by fostering the conversion of regular skin cells into skin-derived precursors (SKPs), leading to improved wound healing and increased collagen production. The ingredient's rich profile of secondary metabolites, including polyphenols, catechins, and terpenoids, underpins its diverse biological activities.
