Conditions
Brief summary
The primary objective of this study involves research to evaluate new collagen (the elastic fibers that provide skin with its strength and resilience) formation in the skin following injections of Sculptra (Poly-L-Lactic Acid or PLLA). The secondary objectives of the study are to better understand the human skin responses to Sculptra and to assess the safety of Sculptra injections.
Interventions
DEVICEPoly-L-Lactic Acid Injection
0.05 mL of poly-l-lactic acid will be injected as depot at three (3) points (a total of 0.15 mL).
