Abstract: Maria Angelo-Khattar1,2 1American Academy of Anti-Ageing Medicine (A4M), Dubai, United Arab Emirates; 2Altaderma Clinic, Dubai, United Arab EmiratesCorrespondence: Maria Angelo-Khattar, Email [email protected]: Poly-L-Lactic acid (Sculptra®, PLLA-SCA®) is a biodegradable bio-stimulating agent composed of irregularly shaped PLLA particles capable of inducing extracellular matrix regeneration. Beyond traditional volumisation, emerging evidence suggests broader epigenetic and adipogenic effects, positioning PLLA as a key agent in regenerative aesthetics.Objective: To retrospectively evaluate long-term outcomes of PLLA-SCA treatment in 28 female patients using 3D imaging analysis, focusing on two protocols; (1) full-face skin firming and (2) skin firming with additional targeted volumisation and/or asymmetry correction.Methods: A retrospective review of clinical data and standardised 3D stereophotogrammetric imaging was performed two years post-treatment. Patients were divided into the two treatment strategy groups. Volume differences were quantified using validated reconstruction software, and clinical outcomes were assessed through physician evaluation and patient-reported satisfaction.Results: All patients demonstrated measurable soft tissue volume formation at two years, ranging from 0.75cc to 6.4cc per vial of PLLA-SCA. Skin quality improvement and facial harmonisation were consistently observed. No untoward effects, such as vascular compromise, nodules, or granulomas, were reported.Conclusion: PLLA-SCA produces sustained soft-tissue formation and skin firming effects, persisting for at least two years. The findings support PLLA-SCA as an effective regenerative agent with long-lasting volumising and tissue enhancing properties.Keywords: poly-l-lactic acid, biostimulators, 3D imaging, facial rejuvenation, epigenetic pathways, regenerative aesthetics
