Centella asiatica has a toning and tightening effect on the skin when applied topically. As a result, it is often found as an ingredient in skin firming creams and lotions. Due to its ability to stimulate collagen production, centella asiatica can improve the appearance of aging skin affected by fine lines and wrinkles. The reduction of collagen in the skin’s supporting matrix is a key reason for the formation of fine lines and wrinkles as skin matures. Its ability to replenish collagen supplies makes centella asiatica a useful anti-aging ingredient.
