What this trial studies

This clinical trial aims to assess the safety profile and tissue interactions following biostimulatory treatments in healthy volunteers. Participants will receive one of three treatments: Poly-L-Lactic Acid, Calcium Hydroxyapatite, or Radiofrequency Microneedling, and will attend five follow-up appointments for evaluations. The study will utilize photographic assessments and ultrasound imaging to monitor changes in the pre-auricular region over a period of up to 24 months.

Who should consider this trial

Good fit: Ideal candidates are healthy men and women aged 30 years and older who are planning to undergo biostimulatory treatments for skin laxity or volume loss.

Not a fit: Patients under 30 years, pregnant or breastfeeding individuals, or those with significant skin issues in the treatment area may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of the safety and effectiveness of biostimulatory treatments for facial rejuvenation.

How similar studies have performed: While there have been studies on individual biostimulatory treatments, this specific combination and comprehensive safety analysis is relatively novel.
