Objectives: Is Micro-coring technique safe and effective for treatment of facial wrinkles? -Micro-coring vs Microneedling and use of insterstial laser lifting -How it works Introduction: Micro-Coring removes cores of skin without formation of scars, thereby tightening skin and reducing skin wrinkling by making tiny punches in the skin using an energy-free, small-gauge needling device removing 5-8% of skin. Micro-needling with unique Pulse Wave & Continuous Wave technology ensures a more stable and deeper penetration of the radiofrequency energy on every dermal layer for revitalized skin and accelerated collagen production. Interstial Laser lifting performed through microfibers as thin as hair (200/300 microns) with wavelength of 1470nm. Materials / method: This prospective, multicenter clinical trial included fifty-one subjects who underwent MCT treatments of the mid to lower face. The primary study endpoint was change in the Lemperle Wrinkle Severity Scale. Secondary study endpoints were change in Global Aesthetic Improvement Scale (GAIS), participant satisfaction, and evaluation of treatment outcome by an independent review panel. All study endpoints were evaluated at 1, 7, 30, 60, and 150 or 180 days after treatment. Results: Improvement in the GAIS was reported for 89.7% (87/97) of treated sites, and average improvement of GAIS was 1.5. Participants reported satisfaction with 85.6% of treatment sites. The independent review panel correctly identified 84.2% of the post-treatment photographs as post-treatment. Procedure bleeding and pain was mild with good healing responses and patient-reported average down time of 3 days. Conclusion: The results of this study demonstrate the safety and efficacy of MCT with the dermal micro-coring device for the treatment of moderate to severe facial wrinkles. MCT led to significant improvement of facial wrinkles with high patient satisfaction and fast recovery time and should be considered in patients who are seeking minimally invasive treatment for wrinkles of the face.
