Acetyl-L-Carnitine Hydrochloride

Acetyl-L-Carnitine Hydrochloride is the stabilized hydrochloride salt form of acetyl-L-carnitine, an endogenous amino acid derivative biosynthesized in the body from lysine and methionine, and used in cosmetics for its ability to support cellular energy metabolism and mitochondrial function in skin cells. It is particularly valued in anti-aging formulations for its role in promoting skin firmness and reducing the appearance of fine lines, as it facilitates the transport of fatty acids into mitochondria, thereby enhancing cellular energy production. Formulators choose this hydrochloride salt specifically because it offers superior water solubility and enhanced stability compared to the free base form, making it well-suited for aqueous serums, eye creams, and targeted anti-aging treatments.
