"i had severe cystic acne all over my face when i was in middle school. i began taking this product, 100mg twice a day, and my skin cleared other than scars. i stopped the medicine in college as i felt i did not need it anymore. at 27, my cystic acne returned worse than it&rsquo;s ever been. i went to the doctor&rsquo;s and they prescribed the same dosage again. when i originally took it i had no side effects other than you get nauseous if you don&rsquo;t take it with food. fingers crossed it works for me again."
