Jawline Sharp Contouring With Hybrid Filler

Having a well-defined jawline is a sign of youth and attractiveness among both men and women. Soft tissue fillers, such as calcium hydroxylapatite (CaHA) and hyaluronic acid (HA) fillers, offer nonsurgical alternatives for rejuvenating the lower face and enhancing the jawline.

The aim of this study was to investigate the use of a premixed combination of HA with cohesive polydensified matrix technology (CPM, Belotero Intense, CPM-I) and CaHA to create a sharply defined jawline.

A total of 126 patients were enrolled in the study and treated with a premixed combination of CPM-I and CaHA using a retrograde fanning injection technique with cannulas. The injection volumes and product ratios were customized according to the patients’ needs.

The cohort consisted of 75 females and 51 males. The average injected volume of premixed CaHA:CPM-I was 5.83 mL. In the majority of patients, a 1:1 syringe ratio of CaHA:CPM-I was applied (n = 81, 64.2%). No adverse events were reported during the 6-month follow-up period.

The hybrid filler approach investigated in this study shows promise for achieving well-defined, long-lasting jawline contours.
