Hyaluronic acid dermal fillers are popular injectable treatments in the field of aesthetic medicine, intended to restore facial volume, smooth out wrinkles, and enhance facial contours with minimal invasiveness. Hyaluronic acid (HA) is a naturally occurring biomolecule within the human body, primarily located in the dermis, connective tissues, and ocular structures. It plays a vital role in maintaining hydration, elasticity, and the lubrication of tissues. As people age, the levels of hyaluronic acid in the body decrease, resulting in volume loss, fine lines, and decreased skin firmness. HA dermal fillers aim to counteract these signs of aging by replenishing volume and improving overall skin texture.
