Abstract

Background: Acne scars present a complex challenge in dermatology and cosmetics, despite advancements in technological interventions such as fractional lasers, microneedling, and surgical procedures. Effective treatment remains elusive for many individuals.

Objective: This study aims to evaluate the efficacy of rotational fractional resection using 1 mm diameter rotating scalpels as a primary treatment for icepick and boxcar scars on the cheeks and glabella region.

Methods: Three patients with acne scars underwent a single treatment session of rotational fractional resection. Evaluation occurred at the 2-month post-treatment mark to assess improvements in scar appearance and potential skin-related side effects.

Results: Following the treatment, significant improvements were observed in the targeted acne scars. Notable enhancements were noted without major skin-related adverse effects, except for minor suture marks.

Conclusion: The outcomes of this study underscore the potential of rotational fractional resection as an innovative and effective approach in treating acne scars. This single-session cosmetic procedure shows promise in yielding lasting and quantifiable results, offering a hopeful solution for individuals seeking comprehensive acne scar treatment.

Keywords: acne scar; minimally invasive; rotational fractional resection; scar treatment.

A 46‐year‐old man displaying a boxcar scar (A) underwent the microcoring procedure on the right side of his cheek. The microcoring system employed was the N‐Derm platform by N‐finders, Korea, Inc, utilizing 1 mm rotating scalpels to excise the boxcar scar, followed by suturing (B). Twelve weeks after the treatment (C).

Acne scars encompass several distinct types, including atrophic scars such as icepick (A), rolling (B), and boxcar (C) scars, which create varying degrees of depressions in the skin. For the Microcoring system, icepick, and boxcar are ideal targets for the treatment.
