Summary
Poly-L-lactic acid (PLLA-LASYNPRO) significantly improved facial wrinkles and volume over six months, demonstrating high patient satisfaction and biological evidence of collagenesis. The aesthetic treatment showed a favorable safety profile with minimal adverse events.
Area of Science:
- Dermatology
- Aesthetic Medicine
- Biomaterials
Background:
- Facial aging involves wrinkles and volume loss.
- Poly-L-lactic acid (PLLA) is a collagen stimulator used in aesthetic treatments.
- PLLA-LASYNPRO is a specific formulation for facial rejuvenation.
Purpose of the Study:
- To assess the clinical efficacy, patient satisfaction, safety, and biological effects of PLLA-LASYNPRO over a 6-month period.
- Evaluate improvements in facial wrinkles and midface volume.
- Investigate the treatment's impact on collagen production and tissue properties.
Main Methods:
- Prospective, multicenter study involving patients treated with PLLA-LASYNPRO.
- Primary endpoint: Wrinkle Severity Rating Scale (WSRS) reduction of at least 1 point.
- Secondary endpoints: Midface Volume Deficit Scale (MFVDS) reduction, patient satisfaction (GAIS), biological changes (ultrasound, elastography, P1CP levels), and adverse events (AEs).
Main Results:
- Significant improvements in WSRS and MFVDS scores were observed, with success rates increasing over 6 months.
- High patient satisfaction reported, with 65.6% rating results as "Much Better" or "Better" at 6 months.
- Ultrasound and elastography confirmed increased tissue density and neocollagenesis; serum P1CP levels significantly increased, indicating collagen stimulation. AEs were mild and self-resolving.
Conclusions:
- PLLA-LASYNPRO effectively treats facial wrinkles and volume loss, leading to sustained aesthetic improvements.
- The treatment is associated with high patient satisfaction and objective biological evidence of collagenesis.
- PLLA-LASYNPRO exhibits an excellent safety profile, supporting its use in aesthetic practice. Further large-scale trials are recommended.
