Treatment of Acne Scar Using Automated Microneedling Device of 2.5 Mm versus 1.5 Mm. A Split Face Study


ABSTRACT:BACKGROUND:Treatment of acne scarring is always a challenge. Microneedling therapy (dermapen) orpercutaneous collagen induction is a new addition to the treatment modalities for atrophicacne scars and has been reported to be simple and effective with fewer side effect thanother modalities.OBJECTIVE:To assess and compare the therapeutic response of microneedling (dermapen) in the treatment ofmoderate and severe types of post-acne scar by using two different depth (2.5 mm on the right side)and (1.5mm on the left side) and to evaluate the adverse effects of this therapy.PATIENTS AND METHODS:Thirty seven patients were included in the study, only 21 patients completed full treatmentcourse 13 males and 8 females, ages ranged from 19 to 35 years. With different types ofatrophic acne scars were subjected to three months of skin microneedling (dermapen)treatment (six sessions at two-week intervals), by using two different lengths (2.5 mm onthe right side) and (1.5mm on the left side).RESULTS:Clinical evaluation of patients showed statistically significant (p-value <0.0001) overallimprovement of post-acne atrophic scars after 12 weeks (after 6 sessions). patients showed goodenhancement of scar appearance and moderate improvement in skin texture. Meanwhile, patientsatisfaction was good when compared to the baseline.CONCLUSION:Skin microneedling is a simple, inexpensive office modality of treatment forthe management of post-acne atrophic scars especially mild and moderate types.
