Clinical Trial Data for Two PLLA Fillers in Arm Contouring, 120-Day Study

20 adults participated in a prospective, randomized, blinded split-arm trial comparing two Poly-L-lactic acid formulations for upper-arm rejuvenation. The dataset includes outcomes such as Subject and Physician Global Aesthetic Improvement Scales, ultrasonography, skin elasticity, and transepidermal water loss measurements through Day 120, along with histological analyses in ten cases. Author Bruna Souza Felix Bravo published the data under a CC-BY-4.0 license on figshare, with a last update in 2026.

Use Cases

• Compare efficacy of two biostimulatory filler formulations based on Subject and Physician Global Aesthetic Improvement Scale scores.
• Analyze changes in skin thickness and elasticity over time based on ultrasonography and elasticity measurements.
• Assess tolerability and safety profiles based on histological findings for inflammation and crystalline residues.
• Model dermal remodeling outcomes based on ultrasound findings and skin thickness data.

Strengths

• Data is from a prospective, randomized, blinded split-arm trial with 20 participants, a recognized study design.
• Includes multiple quantitative outcome measures such as S-GAIS, P-GAIS, ultrasonography values, skin elasticity, and transepidermal water loss.
• Contains histological analysis from ten cases, providing a direct tissue-level assessment.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analysis.
• The dataset is a 102.3 KB PDF file, which is a small document format requiring extraction for structured analysis.
