well i am on day 19 on my juice fast...and i would like to know also...i have problem acne skin..and trying to get rid of it thru juice fasting...however it has not gone away..it is at it's worst at the moment since i have been on the fast...that sucks! but i gotta keep the faith...i heard any skin problems takes 30+ days of fasting to clear up ...so that's why i am in this for the long haul! and i also do the pineapple several per week...for good skin.. so far nada :((
