High vs Low Molecular Weight HA in Skin Boosters: What It Means for Clinical Results

Most practitioners know that hyaluronic acid is the active ingredient in skin booster treatments. Fewer know that not all HA is clinically equivalent — and that the molecular weight of the HA in a product is one of the most important determinants of how that product will behave in tissue, what biological effects it will produce, and which patient profile and treatment goal it is best suited to.
