Sodium hyaluronate(Food grade)

HA is an inherent physiological substance of the skin, and exogenous HA serves as a beneficial supplement to the endogenous HA in the skin. HA with a relatively low molecular weight easily penetrates into the epidermal layer of the skin, promoting the supply of nutrients to the skin and the excretion of waste. Oral hyaluronic acid has been widely used in health foods in developed countries such as Europe and the United States, supplementing the deficiency of hyaluronic acid in the human body.
