Lip filler, also known as lip augmentation or lip injections, is a cosmetic procedure that involves injecting dermal fillers into the lips to add volume, enhance shape, and improve symmetry.
The most common type of filler used for lip augmentation is hyaluronic acid-based fillers. Hyaluronic acid is a naturally occurring substance in the body that helps maintain hydration and volume in the skin. When injected into the lips, hyaluronic acid fillers provide immediate results by adding volume and softening the appearance of fine lines and wrinkles around the mouth.
