Results: Thirty (93.7%) of the 32 patients completed the 6-month therapy. At the end of the treatment complete improvement was observed in 23 patients (76.6%) out of 30. All adverse effects were mild and discontinuation of the treatment was not necessary. Conclusion: Intermittent isotretinoin treatment was found to be a safe and effective choice for patients with moderate acne.
