Hyaluronic acid is a naturally occurring substance in the body, primarily found in the skin, connective tissues, and eyes. Its main functions include: Hydration: HA attracts and retains water molecules, keeping skin plump and moisturized. Elasticity support: It maintains skin elasticity and firmness. Volume maintenance: HA supports the structural integrity of skin and underlying tissues. In dermal fillers, HA is used in a cross-linked form, which allows it to provide both immediate volumizing effects and long-term hydration benefits.
