Summary
Poly-L-lactic acid collagen activator (PLLA-SCA) offers a safe alternative for midface rejuvenation, improving volume, texture, and projection. This treatment regenerates collagen, providing long-term effectiveness for a less tired appearance.
Area of Science:
- Aesthetic medicine and dermatology
- Regenerative aesthetics
- Dermal fillers and collagen stimulators
Background:
- Aging causes lower eyelid and midface depression due to skin thinning, fat atrophy, and pigment changes.
- Current treatments like hyaluronic acid injections have limitations, including patient selection and potential side effects.
- Poly-L-lactic acid collagen activator (PLLA-SCA) stimulates collagen and elastin production, improving skin quality.
Purpose of the Study:
- To present a case series on PLLA-SCA for enhancing maxilla/malar projection, pigmentation, texture, and volume in the lower eyelid-midface area.
- To discuss the technique for PLLA-SCA injections in patients with age-related or congenital midface deficiency.
- To evaluate the safety and efficacy of PLLA-SCA for midface rejuvenation.
Main Methods:
- A case series involving healthy adults with lower eyelid-midface deficiency.
- Injections of PLLA-SCA (Sculptra) diluted to 8-9 mL with sterile water and lidocaine.
- Typically 3 treatment sessions administered every 6 weeks.
Main Results:
- Significant improvements observed in maxilla/malar projection, pigmentation, skin texture, and volume.
- Positive clinical outcomes noted as early as 6 weeks post-treatment.
- Sustained results with minimal touch-ups required for 4-5 years post-treatment; no adverse events reported.
Conclusions:
- PLLA-SCA is a safe and potentially long-term effective treatment for softening the lower eyelid-midface transition.
- It offers an alternative to traditional fillers by regenerating the patient's own collagen.
- The treatment addresses multiple signs of aging in the midface, including volume loss and textural changes.
