acne
"I used isotretinoin for 6 months. Started on a lower dose until I was on 60mg per day. It is the best medication I have ever used and did exactly what my dermatologist promised, after about 4 months my skin started to clear properly and by the time I finished the 6 month course it was glowing. I felt so much better and was able to wear lovely makeup. 
The good: clear healthy skin, 
The negative: slightly dry lips, strictly no alcohol whilst on this medication. 
Well worth every day! Don't be put off by other negative reviews. It will worry you but you are your own self and every body is different."
