MICRONEEDLING IN ACNE SCAR TREATMENT: LITERATURE REVIEW

Abstract

OBJECTIVE: To evaluate, through a literature review, the efficacy of microneedling in the treatment of acne scars. METHODS: Narrative literature review, using the PubMed and VHL databases, using the descriptors "micro needling", "acne vulgaris" and "scar". The chosen articles were dated from 2018 to 2023, totaling 134 articles. Of these, 18 were selected by title and abstract, and in the end, 8 by full reading, based on inclusion and exclusion criteria, analyzing the effectiveness of microneedling. RESULTS: Microneedling can reduce the degree of acne scarring effectively, when well indicated, and it is possible to associate it with other treatments, such as platelet-rich plasma, topical insulin, subcision, CROSS (Chemical Reconstruction of Skin Scars), chemical peeling, botulinum toxin type A and topical products, improving its results. On the other hand, its possible adverse effects include transient erythema, pain, and edema. CONCLUSION: It is concluded that microneedling treatment is effective in reducing the degree of acne scarring, especially when combined with other therapeutic modalities, presenting benefits that outweigh the financial costs and the occurrence of side effects.
