Hyaluronic acid is a naturally occurring substance in the body that is commonly used in cosmetic procedures such as facial contouring. It is injected into the skin to add volume and hydration, which can help to smooth out wrinkles and give the face a more youthful appearance. Hyaluronic acid is also commonly used to enhance facial features such as the lips, cheekbones, and jawline, giving the face a more defined and contoured look.
