Treatment of acne scarring is always a challenge. Microneedling therapy (dermapen) or
percutaneous collagen induction is a new addition to the treatment modalities for atrophic
acne scars and has been reported to be simple and effective with fewer side effect than
To assess and compare the therapeutic response of microneedling (dermapen) in the treatment of
moderate 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 treatment
course 13 males and 8 females, ages ranged from 19 to 35 years. With different types of
atrophic 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 on
the right side) and (1.5mm on the left side).
Clinical evaluation of patients showed statistically significant (p-value <0.0001) overall
improvement of post-acne atrophic scars after 12 weeks (after 6 sessions). patients showed good
enhancement of scar appearance and moderate improvement in skin texture. Meanwhile, patient
satisfaction was good when compared to the baseline.
Skin microneedling is a simple, inexpensive office modality of treatment for
the management of post-acne atrophic scars especially mild and moderate types.
