What Is Hyaluronic Acid?
Dr. Jaliman described the ingredient as a clear, gooey substance that occurs naturally in our bodies, especially in our joints. "Hyaluronic acid plays an important part in the health of our connective tissue, skin's elasticity, and wound healing," she explained. "It's present in all tissues and fluids." However, 50 percent of the hyaluronic acid in our bodies is found in our skin.
Applied topically, the polymer also has the ability to hydrate and plump your skin. "It's a humectant," Dr. Jaliman said, which means it draws water in from its surroundings. "It acts as a sponge and can hold a large amount of water in the skin."
