I like fatgirlslim from Bliss. I was reluctant to try it at first because it's expensive IMO, but I got this kit: http://sephora.com/browse/product.jh...categoryId=B70 to try it and honestly I think it's worth it. The scrub alone is awesome. The night cream has a nice soothing scent too. I didn't notice overnight results and can't vouch for it long term, but I have to say the texture of my skin greatly improves when I use it consistently on my tummy/thighs. I'm 25, btw.
Edit: Sorry, didn't realize this was an old thread that had been bumped... will leave this here anyway in case it helps someone. :)
