Clavicular Augmentation With Poly-d,l-lactic Acid (Juvelook GLAM) using Cannula

Area of Science:

• Aesthetic medicine
• Dermatology
• Plastic surgery

Background:

• Prominent clavicles are a growing aesthetic demand among East Asian patients.
• Poly-d,l-lactic acid (PDLLA) is a collagen-stimulating injectable filler with limited clinical data for clavicular augmentation.

Purpose of the Study:

• To evaluate the feasibility and short-term outcomes of PDLLA for clavicular augmentation.
• To assess patient satisfaction and objective changes in clavicular projection.

Main Methods:

• Prospective, single-arm case series involving 44 East Asian women.
• Bilateral clavicular augmentation using PDLLA via blunt cannula in the subcutaneous plane.
• Outcomes assessed included adverse events, aesthetic improvement, patient satisfaction, and 3D imaging for projection change at 3 and 6 months.

Main Results:

• No major complications were reported within 6 months.
• Transient bruising (19.4%) and swelling (25.8%) resolved spontaneously.
• Mean clavicular projection increased significantly at 3 and 6 months (p < 0.05), with 90.3% patient satisfaction at 6 months.

Conclusions:

• PDLLA clavicular augmentation is a feasible procedure with high short-term patient satisfaction.
• The treatment resulted in a modest but measurable increase in clavicular projection.
• Larger, controlled studies are necessary to confirm long-term efficacy and safety.
