"i&#039;ve been taking 100mg 2 times a day for 3 months now. it has cleared my shoulders/back/chest pretty well as well as my face being mostly clear too. it works best if you take it consistently. i am a very busy 16 year old girl with sports and school. if i skip a dosage i notice a few blemishes on my shoulders appear. if you get on this and you don&#039;t see a difference in a month, call your doctor and ask if they can up your dosage. if you follow the regulations and take it as directed, it works pretty good. i recommend it to anyone who is struggling with finding a face wash to work for them."
