OK, I confess. I am a peel-maniac. I own more than 12 of those (in the range from 1 to 50 USD) and I know how to use them :-).
It's clear to me that there is some psychological factor about scrubs, because I definitely use them more when I'm "on the track" (dieting). There si something very attractive about the "peel it off" thing, which relates to pureness and slimness in my eyes. But there are also myths about skin exfoliation (see http://yummy-secrets.blogspot.com/2010/02/dieting-myths-3.html) that are trying to make a magic of something that is just a pretty cool cosmetic... thing.
But anyway - the reason for this post is my today's "bathroom cooking." I found out that a fresh scrub is sooo much more effective and pleasant to use than those in tubes. In the past I used to make it from salt - but those were just too agressive to the skin. So today I made a super sweet one of sugar, olive oil, lemon juice and shower gel. It smells great and works perfectly. Almost like eating a candy :-).
