    Author: Villani A, Carmela Annunziata M, Antonietta Luciano M, Fabbrocini G.
    Journal: J Cosmet Dermatol; 2020 Sep; 19(9):2174-2181. PubMed ID: 32598509.
    Abstract:
    BACKGROUND: Skin needling, also called "collagen induction therapy," is a nonpharmacological treatment modality that has been increasingly utilized for the treatment of acne scars. AIMS: To review the medical literature and to select the most significative and recent studies regarding skin needling as a treatment for acne scarring, used alone or combined with other treatments. METHODS: A literature search was performed using the PubMed, Medline, and Embase databases, in addition to reviewing the bibliographies of relevant articles. RESULTS: Almost all the articles evaluated showed improvement of acne scars severity after microneedling treatment. When combined with other treatments such as autologous platelet-rich plasma (PRP), chemical peels, filler injections, or laser treatment, a greater improvement was reported. Needling technique is well-tolerated with erythema and dryness representing the most frequent adverse events. CONCLUSIONS: Microneedling is a useful treatment for acne scarring. Further studies are needed to evaluate its efficacy and safety and to create a standardized protocol to adopt for each patient according to the severity of acne scars.
