Dr. Barbara Sturm is one of the most well-known estheticians in the industry, and her products have gained some of the same fame that her facials have over the years since their release. One of the most beloved products in the line is the Dr. Barbara Sturm Hyaluronic Serum. This product was designed to deeply hydrate the skin without adding any extra weight. But what makes this product different from the other hyaluronic acid serums on the market? The key to this serum’s impressive hydrating abilities is the presence of multiple chain lengths of the active ingredient. Hyaluronic acid can come in a variety of molecular sizes or weights. How small or large a hyaluronic acid molecular is will often determine where it will impact the skin. The Dr. Barbara Sturm Hyaluronic Serum utilizes both small and large chain hyaluronic acid molecules. The small chain lengths target the deepest layers of the skin, while the large chain lengths target the surface, giving you a more uniform, and holistic approach to hydrate, rather that addressing at the surface alone.
