Abstract
OBJECTIVE: To assess the effectiveness of the amiea med (amiea med, MT.DERM GmbH, Berlin, Germany) automated microneedling device in reducing facial atrophic acne scars. STUDY DESIGN: Open label, single center. PARTICIPANTS: Healthy males and females, aged 18 to 65 years, with signs of facial atrophic acne scarring were selected. After consenting and satisfying inclusion criteria, each subject underwent four microneedling sessions 30 days apart. Subjects were assessed at baseline and three months after the last treatment. MEASUREMENTS: Acne scars were classified according to Jacob classification. Physician assessment of acne scarring severity was carried out using the Goodman and Baron grading scale. Subjects graded their redness, pain and discomfort on the evening of the treatment and up to seven days posttreatment using a subject diary. RESULTS: Three months after the last treatment, facial acne scars had improved by 0.91 of a grade [CI. 0.78-1.05] according to Goodman and Baron Grading Scale (p<0.001). Improvement in acne scarring was not restricted to severity of grade,with no difference seen in Fitzpatrick skin types. According to Jacob classification, rolling scars showed the greatest improvement, with a mean improvement of 1.06 of a grade at the final assessment (p<0.001). CONCLUSION: This study demonstrates that four microneedling treatments of facial skin, spaced four weeks apart, significantly improves the appearance of facial acne scarring. The treatment is well tolerated with minimal pain, discomfort, and downtime. Side effects appear minor and easily managed compared to other more aggressive technologies. STUDY REGISTRATION: German Register for Clinical studies (DRKS) No [DRKS00013187].
