Histology Clinical Trial
Official title:
A Prospective, Single Blind, Single-center Study Evaluating the Histology and Intradermal Implantation of the Teosyal RHA® Collection of Fillers
The Teosyal RHA® family of products (RHA® 1, RHA® 2, RHA® 3, and RHA® 4) is approved in Canada for the correction of facial wrinkles and folds. In this study, the approved products will be placed in small boluses (0.2 mL) intradermally to allow for punch biopsies of the post-auricular space to be taken. The biopsies will include the injected material and surrounding skin tissue. Biopsies will be taken immediately after implantation of the product and at Day 30 and assessed by an independent blinded pathologist.
