Lip fillers, a type of injectable treatment, are primarily used to augment the volume, contour, and balance of the lips. These fillers are usually made of hyaluronic acid, a naturally occurring substance in the body that helps retain moisture and imparts fullness. The procedure is relatively non-invasive, typically completed in less than an hour, and involves the use of fine needles to administer the filler into designated areas of the lips. The results are often instantaneous, requiring minimal recovery time. Some common side effects are swelling, bruising, and sensitivity, but these usually diminish within a few days. The longevity of lip fillers can range from six months to a year, contingent on the type of filler used and the individual’s metabolic rate.
