Jawline filler, known as jawline augmentation or jawline enhancement, involves the use of dermal fillers to add volume and definition to the jawline area. This treatment targets the jawline, which may appear weak, undefined, or sagging due to genetics, aging, or other factors. During jawline filler treatment, a healthcare provider injects filler into specific areas along the jawline using a fine needle or cannula. The filler material is typically made from substances like hyaluronic acid, calcium hydroxylapatite, or poly-L-lactic acid. The goal of jawline filler treatment is to enhance the shape and contour of the jawline, resulting in a more sculpted and defined appearance. This can help improve the appearance of a weak or asymmetrical jawline, create better facial harmony, and enhance overall facial aesthetics The effects of jawline filler treatment are typically visible immediately, although there may be some initial swelling and bruising. Over the following days and weeks, the filler settles into place, and the full results become apparent. Jawline filler injections can last anywhere from six months to a year or more, depending on the type of filler used and individual factors such as metabolism and lifestyle habits.
