Using poly-L-lactic acid (PLLA) to mimic volume in multiple tissue layers.
Level 5 - mechanism / opinion, no new human data
Narrative review and clinical technique description without empirical trial data.
What was done
Methodological description and narrative review detailing the authors' clinical technique for poly-L-lactic acid (PLLA; Sculptra/Sculptra Aesthetic) injections. The article discusses structural volume changes across facial tissue layers, patient selection principles, and both soft-tissue and supraperiosteal injection approaches.
What was found
The abstract reports no numerical results, sample sizes, or quantitative data. It qualitatively notes that patients with severe lipoatrophy or advanced age and compromised skin integrity require more product volume and more treatment sessions to achieve satisfactory correction.
Why it matters
Provides practical technique guidance on multi-layer facial injection strategies and realistic expectations based on baseline tissue quality for clinicians using poly-L-lactic acid.
Limits
This is an unstructured expert review and technique description without a controlled trial design, predefined outcome measures, or quantitative safety and efficacy metrics.
