Brief Summary

Stylage® XL Lidocaïne is a CE-marketed hyaluronic acid gel indicated for the restoration or augmentation of facial volume by injection into the deep dermis or subcutaneously. Lidocaine hydrochloride is intended to reduce the pain associated with the injection.

In this study 40 healthy subjects between the age of 30 and 65 years, presenting a volume deficit on the face as evaluated by the investigator at inclusion in the study, who have given his/her informed consent and met all the eligibility criteria, will be enrolled.

Subjects will come to a total of 6 visits over a period of 18 months and a screening visit prior to baseline injection. The facial volume variation after baseline injection will be assessed. Treatment responders rate, Global Aesthetic Improvement, volume on the cheekbones, volume on the chin and chin angle (for applicable subjects), subject's satisfaction and safety will be also assessed.

Detailed Description

This is a prospective, uncontrolled, single site study with a blinded evaluator assessing the efficacy of Stylage® XL Lidocaïne on FVLS and GAIS clinical scoring.

The study duration by subject is 18 months with a screening visit (V0) before injection, the baseline visit (injection of Stylage® XL Lidocaïne, V1) and 5 follow-up visits after 1, 3, 6, 12 and 18 months (V2 to V6). At 1 month (V2) an optional touch-up may be done (if needed).

The primary endpoint is the facial volume variation from baseline (D0) to 6 months after treatment initiation measured by an independent evaluator on photographs using FVLS (Facial Volume Loss Scale).

Facial volume variation (evaluated by an independent evaluator) & treatment responder rate, Global Aesthetic Improvement (evaluated by the patient and the doctor), volume on the cheekbones and chin & chin angle (for applicable subjects), subject's satisfaction will be measured at all time-point with a FVLS, GAIS,3D QuantifiCare system, FACE-Q questionnaire (cheekbones and chin) respectively. Safety will be also assessed.

Study Groups

Treated face

The device will be injected on V1 (D0) in the cheekbones (upper part of the cheek) for all subjects and in the chin for 20 subjects minimum and if needed (optional areas) in the temple, and facial oval (mandibular angle and border). A touch-up is possible in one or several of these areas on V2 (M1). Optional treated areas will be at the discretion of subjects and injectors.

Group Type: EXPERIMENTAL

Stylage® XL Lidocaïne

Intervention Type: DEVICE

On V1 (D0), a total volume of 8 mL maximum can be used per subject on the whole face.

On V2 (M1), a possible touch-up can be made according to the injector and subject's opinion which cannot exceed 4 ml.
