Infraorbital Hollows

The goal of this post-market interventional study is to confirm, under real-life conditions, the safety and performance of hyaluronic acid-based dermal fillers intended to modify skin anatomy and facial appearance. Subjects aged 18 years or older seeking aesthetic treatment of the lips, perioral lines, nasolabial folds, cheeks, and/or infraorbital hollows may be included. The main question the study aims to answer is: How long does the effect of the products last? Participants will attend follow-up visits every 6 months after the initial injection, until the end of follow-up at 24 months. During each visit, the investigator will assess performance and safety through a simple clinical examination. At each follow-up visit, subjects will also evaluate the aesthetic improvement compared with their pre-injection appearance. Subjects will be asked about the level of pain experienced during the initial injection. If the subject wishes, a retreatment may be performed at the 12-month or 18-month follow-up visit, provided that the treated area(s) have returned to the pre-injection state.

This is a prospective, multi-center, randomized, no-treatment controlled, evaluator-blinded clinical investigation to identify whether TEOSYAL RHA® 1 is superior to no treatment for the correction of moderate to severe tissue volume deficiencies in the infraorbital region in Chinese adults. Eligible subjects will be enrolled and randomized either to the treatment group or control group in a 3:1 ratio on Day 0. Each subject assigned to the treatment group will receive TEOSYAL RHA® 1 in both Infraorbital Hollows (IOH), whereas subjects assigned to the control group will not receive any treatment. The subjects in the treatment group will be treated with RHA1 for the treatment of moderate to severe tissue volume deficiencies in the infraorbital region on Day 0. All treated subjects will return to the site at 2, 4, 12, 24, 36, and 52 weeks after the last treatment for effectiveness and safety assessments. Each treated subjects will receive a safety phone call 3 days after the initial treatment at baseline, and after the touch-up treatment, if any. Their participation in the trial ends after the completion of the follow up period. All non treated subjects (control group) will return to the site at 2, 4, and 12 weeks after randomization for effectiveness and safety assessments. Their participation in the investigation ends after the effectiveness and safety assessments at 12 weeks after randomization.
