L-alanyl-l-cystine mainly has the following functions in cosmetics:
Moisturizing Effect: L-alanyl-l-cystine has a certain hygroscopicity. It can absorb moisture from the air and retain it on the skin surface, forming a moisturizing film. In this way, it can reduce the loss of skin moisture, keep the skin moist and smooth, and help improve the problems of dry and rough skin.
Antioxidant Effect: This ingredient can act as an antioxidant to help eliminate free radicals in the skin. Free radicals are one of the important factors leading to skin aging, the appearance of wrinkles, and skin dullness. Through its antioxidant effect, l-alanyl-l-cystine can slow down the oxidation process of the skin, protect the skin from the damage of free radicals, and play a role in delaying skin aging.
Promoting Skin Repair: It helps to promote the metabolism of skin cells and enhance the self-repair ability of the skin. For damaged skin, such as skin damage caused by ultraviolet radiation, environmental pollution, or improper daily skin care, l-alanyl-l-cystine can accelerate the renewal and repair of skin cells, enabling the skin to return to a healthy state.
Enhancing Skin Barrier Function: L-alanyl-l-cystine can participate in the formation of natural moisturizing factors in the stratum corneum of the skin, helping to maintain the integrity and normal function of the stratum corneum, enhancing the skin's barrier function. It can prevent harmful substances from the outside, such as bacteria and pollutants, from invading the skin, and at the same time, prevent the loss of moisture and nutrients in the skin.
