If the truth be told the top acne product that delivers clear skin is accutane. However this drug, which is generally medically prescribed, comes with a health warning. If you have other weaknesses accutane will find them. That is why Drugs.com has all these caveats for would be users of accutane.
They mention in particular possible side effects as follows:- swelling of your face, lips, tongue, or throat, hives, difficulty breathing, sleep problems, changes in behavior, thoughts of suicide or hurting yourself, depressed mood, trouble concentrating, crying spells, aggression or agitation, hallucinations, sudden numbness or weakness especially on one side of the body, sudden and severe headache or pain behind your eyes, blurred vision sometimes with vomiting, hearing problems or hearing loss, ringing in the ears etc. etc.
Those caveats were aimed mainly at women but accutane has been known to produce side effects in men also including liver toxicity.
However you don't need a sledgehammer to crack a nut. If you have signs of acne - pimples, blackheads, whiteheads or cysts (bigger deeper pimples) the first thing you should do is educate yourself about the condition. Don't spend your youth wandering about on the internet trying to re invent the wheel. The dogs in the street know what acne is - all that stuff about sebaceous glands and secretions of oily sebum, hormones and that rubbish - after all you are reading this because you want a cure - fast. So here is my considered advice.
Just sign up for a good acne relief programme. That's what I did. I followed all the basic instructions and now my skin is as near perfect as it can ever be.
