I'm 17 weight 85kg and have premature greyhair. Acne started when I was 15 before that I only had a few small pimples on my forehead which was unnoticeable. But it's been severe since the start of 2015. I've also visited a doctor she prescribed me with 20mg accutane I've used it for 2 months but no changes..... Please somebody help me. Thankss
