Dont believe that the food you eat causes acne, thats a myth. You wanna nip this shit in the bud, theres only one proven way. Get on a moderate dose of accutane and run it for 6 months. You will never have problems with acne again, and if you do have any re-occurance, a small dosage of 20mg ED will keep you perfectly clear. People on here will tell you how awful the side effects are and that you will be hating life while on it, but that isnt true if your dosage isnt high. I suggest 40mg ED for the first couple months, then you might be able to take it down if you get the results your looking for. The only side effect you will experience at that dosage is dry lips. Possibly slightly blurred vision caused by your body releasing tears to combat the dryness of your eyes (this is easily controlled by using eye drops throughout the day)
Your acne should be gone after 1 month and you will stay clear as long as you continue to take it. Its also the only medication that will work afterwards while your not taking it. Quite possibly you will be clear for life after a 6 month course. Some have re-occurance when AAS is put into the mix but this is easily controlled by running a low dosage (20mg ED) while on cycle.
Also there is nothing better for acne induced by steroid use. IT will completely eliminate acne on your back, shoulders, and chest that result from steroid use. Also, this type of acne will go away extremely fast. The acne on your face that is not caused by steroids will also clear up, although it may take a little longer for it to work (2-3 months). But it WILL work!
