Lip fillers are a suitable treatment option for healthy, adult individuals who are dissatisfied with the volume or thinness of their lips, experience irregularities in lip shape or symmetry, or are bothered by fine lines around the mouth (perioral lines). Historically, plastic surgeons have frequently utilized lip augmentation techniques, including fat grafting and hyaluronic acid fillers, to address facial deformities such as cleft lip. Today, with the availability of safe and reliable pre-filled hyaluronic acid lip fillers, it is possible to enhance lip volume, correct shape, and improve symmetry in an office or clinic setting, providing a more aesthetically pleasing appearance.
