About
A clever hybrid — vitamin C bonded to hyaluronic acid. Delivers brightening and hydrating benefits simultaneously while being more stable than pure vitamin C. Innovative and well-tolerated.
Ascorbylpropyl Hydrolyzed Hyaluronate is a conjugate of ascorbic acid (vitamin C) linked via a propyl spacer to hydrolyzed hyaluronic acid. This molecular design combines the antioxidant and collagen-stimulating properties of vitamin C with the moisture-binding capacity of low-molecular-weight hyaluronic acid. The conjugation stabilizes the ascorbic acid moiety against oxidation, a common problem with vitamin C in cosmetics. Functions as a humectant, skin protectant, and light stabilizer per CosIng. No GHS hazard classifications. Both component parts have excellent safety profiles.
