"i&#039;ve had cystic acne for 15 years and was finally prescribed isotretinoin at the age of 27. i went to a private dermatologist who prescribed the medication, then i switched to the nhs. i&#039;m currently on month 5 out of 6 and acne free at 70mg per day. it was month 4 when i became free of acne, so it does take a while to fully kick in. side effects - severe eczema on my hands, very dry eyes and lips. my only regret is i didn&#039;t get on this medication 10 years ago, which would have prevented scarring and emotional issues. i am so angry with the nhs for refusing me this medication back in 2007."
