This study is being undertaken to:
- evaluate the degree of correction attainable with DL6049 (injectable poly-L-lactic acid)compared to a commercially available CosmoPlast™ Collagen Implant in the treatment of dermal nasolabial fold wrinkles at 13 months following the last application of study treatment.
- Document the types and incidence of adverse events reported with DL6049 (injectable poly-L-lactic acid)compared with CosmoPlast™ Collagen Implant. Long term adverse events will be assessed for an additional 12 months following discharge from the main study in subjects treated with DL6049.
