Number of Participants with Procedure-Related Adverse Events by Symptom and Severity
Adverse events related to the procedure (microneedling with or without Vitro Biopharma Exosome Serum) will be assessed at each in-person follow-up visit using the Clinical Safety Assessment (Protocol Appendix D). Physician-assessed events include erythema, edema, and scabbing/peeling/dry skin. Subject-reported events include pain, pruritis, paresthesia, and discomfort. Each event will be recorded as present or absent with severity graded as Mild, Moderate, or Severe. Number of participants with each event by severity grade will be reported for each treatment side.
Time frame: Procedure Day through Day 90 follow-up (assessments at 1 hour, Day 1, 7, 21, 45, 46, 52, 66, and 90)
Difference Between Intervention and Control Sides in Incidence of Anticipated Microneedling-Related Adverse Events
For each anticipated microneedling-related event (erythema, edema, scabbing/peeling/dry skin, pain, pruritis, paresthesia, discomfort) defined in Protocol Appendix D, the number of participants reporting the event on the intervention (Exosome Serum) side will be compared to the number reporting the event on the control (no Exosome Serum) side at matched post-procedure time points.
Time frame: Post-procedure Days 1, 7, 21, and 45 on each treatment side (study Days 1, 7, 21, 45 for control; study Days 46, 52, 66, 90 for intervention)
Change from Baseline in Global Aesthetic Improvement Scale (GAIS) Score by Blinded Evaluator
Aesthetic improvement of each treatment area relative to baseline images will be rated by a blinded evaluator using the 5-point GAIS (1 = Exceptional Improvement, 2 = Very Improved, 3 = Improved, 4 = Unaltered, 5 = Worsened). Mean GAIS score will be reported per treatment side at each assessment, and the difference between intervention and control sides will be reported.
Time frame: Day 45 and Day 90 follow-up (live assessment); post-Day 90 image-based assessment
Change from Baseline in Transepidermal Water Loss (TEWL)
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
TEWL will be measured at each treatment area using a topical probe with temperature and relative humidity sensors, reported in g/m²/h. Mean change from baseline at each post-procedure time point and the difference between intervention and control sides will be reported.
Time frame: Time Frame: Pre-Treatment (baseline) and follow-up Days 1, 7, 21, 45, 46, 52, 66, and 90
Change from Baseline in Subject-Reported Clinical Global Impression-Improvement (CGI-I) Score
At each follow-up visit, subjects will rate overall appearance of each treatment area compared to before the procedure using the CGI-I (1 = Very Much Improved, 2 = Much Improved, 3 = Minimally Improved, 4 = No Change, 5 = Minimally Worse, 6 = Much Worse, 7 = Very Much Worse), per Protocol Appendix F. Mean score per side at each time point and the between-side difference will be reported.
Time frame: Follow-up Days 1, 7, 21, 45, 46, 52, 66, and 90
