Abstrakt: Post-acne scarring is the most common permanent consequence of acne vulgaris. Subcision is an intervention in which a needle or blunt cannula is inserted under the scar and moved back and forth to cut fibrotic strands and form new connective tissue, thereby elevating the atrophic scars. In this study, we reviewed the efficacy and adverse effects of different subcision techniques alone or in combination with other modalities to manage acne scars. The terms (subcision), (subcision AND acne scar), and (subcision AND scar) were searched in PubMed and Google Scholar. We included all available reports on clinical trials written in English and published before June 2022. A total of 16 relevant articles were identified after reviewing the abstracts and full texts. Four articles compared blunt cannula-based subcision as a modified technique with needle-based subcision as a conventional method, while the others investigated the combination of subcision with other modalities. According to our findings, subcision is a safe and effective method for treating atrophic acne scars. Needle-based subcision and cannula-based subcision offer comparable efficacy, with the latter causing fewer side effects and inducing greater patient satisfaction. Combining subcision with the application of autologous tissues (platelet gel) or artificial materials (hyaluronic acid gels and threads) as fillers can improve outcomes and prevent the re-depressing of scars, as can its combination with frequent suctioning. Combinations with microneedling or fractionated microneedle radiofrequency have also been safe and effective. We conclude that modifications of the subcision procedure lessen its side effects, and combination therapies improve its efficacy.
