If you had only very small amount of acne, mild acne, then why did you use a dosage that high? I don't think GLL is a very reliable source because he never had acne which is why he never was forced to really learn about this shit for real.
I got very mild acne, mostly bacne, and started microdosing myself with 3x20mg per WEEK. After 3 months I have gotten good results but still pretty strong side-effects: dry skin, lips and rash in armpits etc. Also got very dry joints/tendons which sucks ass.
According to research, supplementing with vitamin D & E while on accutane helps with the side-effects because vitamin A(which is what accutane basically is) and D have antagonist interaction with each other. Don't take my word for it though,

Zinc, D, Retinol, B-vitamins and avoiding crap surely help, but some people have different causes of acne where they may not really help. I have had mild acne since my teens and have tried(and I am currently trying) all this crap which is supposed to work, like many others who are doing the same without any luck.
It is hard to find good quality acne information on internet because acne is one of the most profitable markets out there and thanks to the millions of internet marketers, there are acne niches for every possible fatty acid, mineral, vitamin, (dry) brushing, natural oil/food/miracle shit, washing style, towel type, satanic ritual for acne, diet etc. where everyone is marketing themselves as the miracle cure with very convincing marketing pitches, "studies", personal experiences and whatnot.
Accutane works for most of the people and very well. It is also backed up very well by science. It is not bullshit. It works but it can be very rough on you if you go with too high dosages. You can maximize the absorption of accutane by eating it with a high fat meal(as far as I remember, studies show that taking it on a empty stomach may reduce absorption for 50 %) I am a lifter with tested high-end testosterone as a natty lifter, and as a result I have had horribly oily skin since I remember. Oily skin can cause acne and clogged pores. Accutane helps with this problem like nothing else -- nowadays my face is
too dry.
Don't wash your face with any product -- really? I tried that too. Many who have large pores and oily skin will have then a serious problem with blackheads. It is not about avoiding all face washes but avoiding the bad ones and choosing the good ones. I believe that the best strategy to deal with acne is to treat it both internally and externally. Salicylic acid, BP and antioxidant creams have been shown to work very well for acne(search pubmed for that).
