In the case of aging, it can be prevented through diet and exercise therapy. In the case of aging, wrinkles can be treated by using laser, filler, Botox, etc. However, there is an inconvenience to receive. The lifting techniques have been developed as an alternative to anti-wrinkle treatment methods in order to compensate for these disadvantages.
In this study, we have developed a system that shows the effect of improving skin wrinkles by fusion of CDT and RF high frequency to suture which has been approved for safety by suture. The thread tightly fixed to the skin tissue was mechanically stimulated by the RF high frequency to induce collagen and elastin synthesis, thereby reducing the wrinkles of the skin.
The primary efficacy of this study was evaluated by the ratio of WSRS (wrinkle degree evaluation) scores of the wrinkles of both arms before and 12 weeks after the operation, Of the 55 patients, 53 were successful and 96% were successful. In addition, the 97.5% lower limit of the one-sided confidence interval was 91%, which was higher than the minimum acceptable rate of 72%, demonstrating the high performance of the test instrument.
In conclusion, this clinical trial demonstrates that a suture operation system combining CDT and RF high frequency can be effectively used to improve facial wrinkles.
The improvement of the wrinkles of the test equipment is more characteristic as the time elapsed compared to the time immediately after the procedure, but the improvement of the wrinkles is maintained permanently due to the collagen regenerating effect even after the test equipment is absorbed which is expected to be safe and effective for people who want to improve wrinkles for a long time.
In addition, the lifting technique which has the effect of spreading the wrinkles by stimulating the skin layer itself, unlike the existing Botox, filler and fat graft, is in demand in the modern society which is particularly interested in aging and beautiful appearance and aging prevention. It is expected that it will be useful for users who want to improve skin aging.
