Lip filler, also known as lip augmentation or lip enhancement, is a cosmetic procedure aimed at increasing the fullness and volume of the lips. This procedure involves injecting dermal fillers, which are typically composed of hyaluronic acid, a substance naturally found in the body, into the lips. Hyaluronic acid fillers attract water molecules, leading to plumper lips with improved shape and definition. Lip fillers can be used to enhance the size of the lips, create a more symmetrical appearance, define the lip borders, and reduce the appearance of fine lines around the mouth.

The procedure is performed by qualified healthcare professionals, and typically takes about 15 to 30 minutes to complete. Results are immediate, although there may be temporary swelling or bruising. The effects of lip fillers usually last several months .
