“…As reported by Kwon et al [4], TLB-induced scars greatly improved. Insufficient contact of the tip in the central pre-tarsal regions may result from using a non-needle vacuum edge line or inappropriate needle depths.…”

“…The Inus unit was developed by Medromed Division Ltd. (Seoul, Korea) to rejuvenate eyelids. It is equipped with a specialized apparatus known as the vacuum edge line that allows easy and precise insertion of microneedles into lax skin with a reduced degree of pain and swelling during the procedure [4].…”

“…In recent years, several types of RF devices have been developed and used for non-invasive lower eyelid rejuvenation [3]. Among them, Inus is unique in that it delivers its bipolar RF current through a specialized vacuum edge line, ensuring optimal needle insertion into sensitive areas with high skin laxity, such as the eyelids and neck [4].…”

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.

Microneedles (MNs) have drawn rising attention owing to their merits of convenience, noninvasiveness, flexible applicability, painless microchannels with boosted metabolism, and precisely tailored multifunction control. MNs can be modified to serve as novel transdermal drug delivery, which conventionally confront with the penetration barrier caused by skin stratum corneum. The micrometer-sized needles create channels through stratum corneum, enabling efficient drug delivery to the dermis for gratifying efficacy. Then, incorporating photosensitizer or photothermal agents into MNs can conduct photodynamic or photothermal therapy, respectively. Besides, health monitoring and medical detection by MN sensors can extract information from skin interstitial fluid and other biochemical/electronic signals. Here, this review discloses a novel monitoring, diagnostic, and therapeutic pattern by MNs, with elaborate discussion about the classified formation of MNs together with various applications and inherent mechanism. Hereby, multifunction development and outlook from biomedical/nanotechnology/photoelectric/devices/informatics to multidisciplinary applications are provided. Programmable intelligent MNs enable logic encoding of diverse monitoring and treatment pathways to extract signals, optimize the therapy efficacy, real-time monitoring, remote control, and drug screening, and take instant treatment.
