I've done the whole drinking tons of lemon water for skin thing and i've found that for ME, it doesn't affect my skin one way or another. With that said, it is good for your body none the less and it's cheap so no reason not to do it. I wouldn't go into it having expectations though.

That's what I thought, but maybe I'll try it anyway just to detox a bit

My skin was so good for a while when I drank lemon water everyday, then I thought I was done w/ acne so stopped drinking and started breaking out again. I started drinking lemon water again 3 weeks ago, and while I still get a few zits/whiteheads now and then, my skin's been a lot better! Popped acnes/scrapes also heal faster now.
