Background: Microneedling has been shown to be a clinically effective and safe treatment for comedonal acne vulgaris. The aim of the present study was to compare the clinical effectof microneedling and the most commonly used topical drug, tretinoin, in the treatment of comedonal acne.Methods: Patients with comedonal acne (n = 82) were randomized to receive topical tretinoin (n = 41) or 6 sessions of microneedling (n = 41) over a period of 3 months. Objective assessments suchas changes in acne severity score by global acne grading system (GAGS) and patients’ subjective satisfaction were investigated at the baseline, at the end of the treatment period, and at the3-month follow up.Results: GAGS was significantly reduced in both microneedling (7.8±3.8 to 3.5±2.6) and tretinoin (8±3.8 to 6.6±3.2) groups at the end of the treatment course compared with the baseline. Theoverall acne severity index reduction in microneedling group was significantly higher than that of the tretinoin group (P<0.001). Improvement in acne severity was also more permanent bymicroneedling. The severity of acne in tretinoin recipients was increased to 8.2±3.2 at the follow-up visit, while it remained nearly unchanged in the microneedling group. (3.3±2.4). Patients’subjective assessment concerning acne improvement was significantly more satisfactory in microneedling group (P<0.001).
Conclusion: Compared with tretinoin, microneedling seems to be a more effective, permanent and satisfactory treatment in the treatment of comedonal acne.

There are many patients with inflammatory acne vulgaris who are not compliant or eligible to consume acne medications, such as oral antibiotics or isotretinoin. PubMed and Medline databases were searched for all related articles. All finding were summarized and chronologically presented in the tables. Nonmedical device-based therapies largely improve the treatment of active inflammatory acne vulgaris, especially in patients who are not compliant or eligible to consume acne medications, do not respond to these drugs over a specified period of time, or do not sustain in the remission phase.

Background: Microneedling is recently used to treat skin scars mostly atrophic scars; however, there are limited data about its effectiveness on hypertrophic burn scars. Carbon dioxide (CO2) laser is an effective method for the treatment of burn scars. Here, we aim to compare the efficacy of microneedling to CO2 laser in the treatment of hypertrophic burn scars in a randomized clinical trial. Methods: Patients with second and third-degree burn scars (n=60) were randomized to receive 3 sessions of microneedling (n=30) or CO2 laser (n=30), 4-6 weeks apart. The outcomes, including physical characteristics of the scar scored by Vancouver Scar Scale (VSS) and patients’ satisfaction with the treatment measured by Visual Analogue Scale (VAS), were investigated at baseline, at the end of the treatment period, and at the 3-month follow-up. Results: The VSS score at the follow-up visit showed a significant reduction from 6.63±1.95 to 3.8±2.3 in the microneedling group and from 7.1+2.3 to 5.6±1.7 in the CO2 laser group; while, the reduced VSS score was significantly higher in the microneedling group (P<0.05), especially in reducing the thickness (P=0.001) and pliability (P=0.001) scores. The patients’ subjective assessments for acne improvement were significantly more satisfactory in the microneedling group (P=0.025).
Conclusion: Microneedling seems to be an effective method to improve hypertrophic burn scars. It also causes better scores in the physical characteristics of scar and the patients’ satisfaction compared to the CO2 laser at the 3-month follow-up.
