Post acne scarring was present in 46.6% of the patients. Majority of the patients (67.3%) had grade 2 acne. Symptoms and signs of hyperandrogenism were present in 14 female patients.

Conclusions: Adult acne is more common in females. Persistent acne is more common than late onset acne. Patients with persistent adult acne are more prone to develop nodulocystic acne and acne scars.
