Hydrolyzed Hyaluronic Acid Best Humectant Hydration Hydrolyzed Hyaluronic Acid at a glance Hydrolyzed form of hyaluronic acid Has a lower molecular weight than hyaluronic acid More readily penetrates skin Good moisturizing ingredient Hydrolyzed Hyaluronic Acid description Hydrolyzed hyaluronic acid is hyaluronic acid that has gone through the process of hydrolysis, which involves changing an ingredient from one form to another by the addition of water or enzymes. In this case, it results in a form of hyaluronic acid with a lower molecular weight, meaning it can more readily penetrate skin (pure hyaluronic acid is a large molecule). That lower molecular weight results in increased hydration in skin’s surface layers. This doesn’t mean that hydrolyzed hyaluronic acid is better than non-hydrolyzed hyaluronic acid, simply that it works differently. It’s good to use multiple forms of hyaluronic acid (including the more bio-available sodium hyaluronate) to make sure your skin care routine is as robust as possible. Usage levels of hydrolyzed hyaluronic acid in skin care typically range from 0.1–0.5%. Related ingredients: Hyaluronic Acid Sodium Hyaluronate Hydrolyzed Sodium Hyaluronate
