Isotretinoin
"This medication has given me a love hate for it, I had horrible cystic acne all over my face neck shoulders chest and back! I have been on the medication 3 weeks now and have seen a drastic improvement! I have tried other medications that yielded no results at all. If you want to start taking this medication for your acne I recommend it but be warned the side effects are nasty! I have the worst joint pain in my feet and ankles every morning and it last for a few hours also my lips have been very dry and I have been applying way too much carmax.  my face has dry spot from where the acne is clearing up and that doesn't look too attractive either. All in all this medication works and you will love the results but the side effects suck"
