Description détaillée
The investigational product is composed of a mixture of polydioxanone and sodium carboxymethylcellulose. The polydioxanone content is as follows: Ultracol 200: 150 mg ±10%, Ultracol 100: 75 mg ±10%. The key difference from the closest analogs (AestheFill® V200, Sculptra™, Ellagen PLLA+CMC 1000 mg) is the presence of polydioxanone in the investigational product.
Thus, the analyzed analogues are not fully interchangeable medical products. The combined composition of Ultracol has not been studied properly. Therefore, during the clinical study, it is necessary to check the safety and effectiveness of a medical product with a combined composition - polydioxanone and sodium carboxymethylcellulose.

Expérimental: Experimental Group
ULTRACOL Intradermal Implant (Polydioxanone-based).
All 23 adult subjects (22 female, 3 male; mean age 51.1, range 37-70) received intradermal injections of ULTRACOL using linear-retrograde technique into the lower dermis or hypodermis.
ULTRACOL 100 (100 mg/vial, reconstituted in 1 mL water for injection) used in all 23 patients; ULTRACOL 200 (200 mg/vial, reconstituted in 2 mL water for injection) used in 20 patients.
Mean 1.87 injections per patient.
Maximum dose: 3 mL per procedure.
Treatment zones: nasolabial folds, cheeks, zygomatic area, perioral/periauricular regions, facial oval.
Follow-up: Day 30, 60, 160.
