Analysis of Safety and Tissue Interaction of Injectable Biosmulators
Sponsor: Universitätsklinikum Hamburg-Eppendorf
Summary
The goal of this clinical trial is to analyse tissue changes in the pre-auricular region after injectable (Poly-L-Lactic-Acid/Calcium-Hydroxylapatit) biostimulatory interventions in healthy volunteers. The main questions it aims to answer are: How is the Safety Profile of injectable Biostimulatory Treatments? How are the Tissue Interactions after injectable Biostiomulatory Treatments? Participants will: * Recieve one of 2 possible biostumulatory treatments (PLLA/CAHA/ * Attend 4 follow-up appointments after treatment for checkups, surveillance and examinations.

Interventions
Poly-L-Lactic Acid (Sculptra) injection
1 to 2 sessions at intervals of 4 to 6 weeks are planned with PLLA (Sculptra®, Galderma Laboratories). PLLA will be injected into the face or neck region using a blunt cannula. For reconstitution, 7 ml of saline solution and 1 ml of 1 % lidocaine will be used. 5 minutes of massaging for 5 times a day are recommended.
Calcium Hydroxyapatite
For CaHA treatment (Radiesse®, Merz Pharma; HarmonyCa®, Allergan), 1 session is planned. The face (cheeks, jawline) or neck will be augmented using a blunt cannula, either diluted (Radiesse® 1:0.2 - 1:2) or undiluted (HarmonyCA®) depending on the product and the region being treated.
