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.
