Hyaluronic Acid: What It Really Does for Your Skin

Send us Fan MailHyaluronic acid is everywhere, in skincare, in supplements, and in injectable fillers. But do we really understand how it works?Today, I explain what hyaluronic acid actually is, how it functions in our body, and why it is far more than just a “moisture magnet.” We discuss the difference between high and low molecular weight hyaluronic acid, how it behaves on the skin surface, and whether it can truly penetrate deeper layers. I also address important questions about oral supplementation, injectable fillers, and their long-term impact on skin aging.
