Brief Summary

The clinical study is designed to prospectively evaluate the safety and effectiveness of TEOSYAL® TPVM when compared to COMPARATOR for the remodeling of the lower face

Detailed Description

This is a prospective, randomized, blinded evaluator, multicenter, clinical study to evaluate safety and effectiveness of TEOSYAL® TPVM versus COMPARATOR for the remodeling of the lower face.

Subject will be enrolled in the study based on evaluation of their chin retrusion severity.

For the purpose of this study, all injections will be done by principal investigators (PIs) with several years of experience in aesthetic treatment.

An external aesthetic and cosmetic surgeon will act as a BE to assess the performance of the treatment and the product based on photographs.
