acne annhilator isnt anything special. just salicylic acid, you can just get some product like it at the store. the reason for no alcohol with accutane is because they both damage the liver. if you do drink, ust make sure you drink alot of water, because accutane drys you up and alcohol dehydrates your body, so stay hydrated.
you can try tretinoin cream/gel. its like a topical accutane, not as effective but i did see better results fromt hat then i did from any otc products.
