Effect of microneedle radiofrequency on scars of transcutaneous lower blepharoplasty
Kwon Hana,Chang Hosun,Kim Ha-Young,(Safi)Kang Kyoungjin 대한미용의학회 2021 대한미용의학회지 Vol.5 No.2
Despite the popularity of transcutaneous lower blepharoplasty (TLB) for the correction of the aged lower lids, ectropion, scar long the incision line, persistent skin laxity with fine wrinkles remain to be a huge setback associated with the procedure. With the advance of recent technologies, scar treatment methods using various kinds of devices have been widely adopted. Among them, fractional microneedle radiofrequency (FMR) has been proven to be highly effective on the improvement of acne scars, widened pores, and skin laxity by means of soft tissue regeneration. A fractional microneedle device called the InusTM developed in Korea exhibits unique properties of delivering bipolar radiofrequency current through specialized vacuum edge line for optimal needle insertion into highly sensitive areas such as the eyelid and the neck. Usage of the InusTM to treat patients experiencing complications from TLB have shown remarkable improvement in various aspects not only limited to the improved appearance of ectropion, scars, wrinkles, skin thickness and laxity, but also the contour of the eyelid and the overall facial volume, and shape. The report will delineate findings from three clinical cases that suggest the efficacy and safety of FMR on the rejuvenation of the lower lids.

Background: Fractional microneedle radiofrequency (FMR) devices are used for non-invasive facial rejuvenation, with aging lower eyelids a popular area for improvement. However, treating lax eyelid skin, particularly determining the exact depth to insert the needle, remains challenging. Objective: To evaluate Inus—an FMR device that uses a bipolar current with a specialized vacuum edge line for optimal needle insertion in lax skin—on aging lower eyelids. Methods: Eleven Korean women (22 eyes) with aging lower eyelids who visited the Seoul Cosmetic Surgery Clinic in 2017 were included. After applying topical anesthesia, an Inus disposable tip with 25 insulated microneedles was used on the lower lids and lateral canthal regions, including temporal hollows. Microneedles of depth 1.0 mm or 0.8 mm were used to apply FMR of 0.5 MHz or 2.0 MHz, respectively, to the entire lower lid during three sessions at 2-week intervals. Morphological and statistical analyses of changes in the horizontal palpebral width, canthal tilt, and distance of the lid-cheek junction were performed using pre-and postoperative photographs. Results: Improvements in lax, deflated, wrinkles on the lower eyelids with scarring, and syringoma were observed. The lower lid contour changed from round to straighter, indicating improved laxity. Decreased lid-cheek junction (p<0.05) and increased canthal tilt (p<0.05) and horizontal palpebral width (p<0.05) were estimated. The mild erythema disappeared within 1-2 days. Mild ectropion (one case) in the case of protruded eyes with thin skin and unexpected transverse wrinkles at the medial part of the lids (two cases) were observed. Conclusion: Total rejuvenation of aging lower lids without serious complications was demonstrated. Therefore, Inus is suitable for treating aging lower eyelids safely.
