Objective: As the population ages, facial plastic providers must remain aware of the treatments to prevent and reverse the external signs of aging. In the mandibular region, skin laxity and soft tissue sagging in the jawline may lead to jowling and chin ptosis along with reduced chin projection. While surgical procedures, including chin implantation, may be performed, nonsurgical procedures are becoming increasingly popular due to their temporary, noninvasive, yet effective methods. This review covers the use of hyaluronic acid, calcium hydroxylapatite, poly-l-lactic acid, and polymethyl methacrylate in the jawline.
Methods: PubMed was searched for data on the mechanism of action, pertinent anatomy, indications, contraindications, technique, and evidence supporting the safety and efficacy of the fillers.
Results: There are a wide variety of fillers available for use in the lower face with unique characteristics and application methods. While the advantages of injectable fillers include relatively affordable cost, minimal patient discomfort, and limited recovery times, taking measures to prevent short- and long-term complications is necessary for optimal results.
Conclusions: Understanding the benefits and limitations of injectable fillers in the jawline can help providers appropriately counsel and treat patients.
