Jawline Sharp Contouring With Hybrid Filler.

Area of Science:

• Aesthetic Medicine
• Dermatology
• Plastic Surgery

Background:

• A defined jawline is associated with youth and attractiveness.
• Nonsurgical rejuvenation options include soft tissue fillers like calcium hydroxylapatite (CaHA) and hyaluronic acid (HA).
• This study explores a novel hybrid filler approach for jawline enhancement.

Purpose of the Study:

• To evaluate the efficacy and safety of a premixed combination of HA with cohesive polydensified matrix technology (CPM-I) and CaHA.
• To assess the creation of a sharply defined jawline using this hybrid filler.
• To investigate patient outcomes and adverse events over a 6-month follow-up period.

Main Methods:

• 126 patients received injections of a premixed CPM-I and CaHA combination.
• A retrograde fanning injection technique with cannulas was employed.
• Injection volumes and CaHA:CPM-I ratios were individualized, with a 1:1 ratio being most common.

Main Results:

• The study included 75 females and 51 males.
• The average injected volume was 5.83 mL of the CaHA:CPM-I mixture.
• No adverse events were reported during the 6-month follow-up, indicating a favorable safety profile.

Conclusions:

• The hybrid filler approach using CaHA and CPM-I demonstrates significant promise for jawline contouring.
• This method offers a viable nonsurgical option for achieving well-defined and durable jawline results.
• The combination of HA and CaHA fillers provides a safe and effective solution for lower facial rejuvenation.
