Cosmetic grade hydrolyzed sodium hyaluronate is a lower molecular weight form obtained by further decomposing hyaluronic acid using specialized enzymatic hydrolysis technology, resulting in enhanced skin penetration. Its molecular weight typically ranges from 3000 to 10,000 Da, allowing it to quickly penetrate the stratum corneum and provide immediate hydration and repair. It is a common functional active ingredient in high-end skincare formulations.
