1Drs. Munia and Parada are in private practice in Sao Paolo, Brazil.
The vector technique using poly-L-lactic acid (PLLA) offers a safe and effective alternative for improving facial flaccidity. This nonsurgical cosmetic procedure enhances facial morphology and skin sagging with lasting results.
Area of Science:
- Aesthetic Medicine
- Dermatology
- Cosmetic Surgery
Background:
- Growing demand for non-surgical cosmetic procedures.
- Vector technique shows promise for facial aesthetics but typically uses hyaluronic acid, risking vascular complications.
- Need for safer, longer-lasting alternatives like poly-L-lactic acid (PLLA).
Observation:
- Three female patients (41-55 years) with facial flaccidity were treated.
- PLLA was injected using the vector technique in the posterior temporal region.
- Dosage: 2mL (upper), 1.5mL (midpoint), 1.5mL (bottom).
Findings:
- All patients exhibited improved facial morphology.
- Significant enhancement in facial support and stretching observed.
- Reduction in skin sagging across all treated facial regions.
Implications:
- PLLA vector technique is a viable option for treating facial flaccidity.
- Offers harmonious and progressive facial rejuvenation.
- Potential for longer-lasting aesthetic benefits compared to hyaluronic acid.
