I read about this on another forum, lots of good feedback on it, so I had to try it myself before passing it along:

Miracle Whip - yes, the mayo-type salad dressing/sandwich spread makes a great exfoliant!

Basically, you spread on a thinish layer of the stuff, let it dry approx. 20 mins...use a tissue or facecloth to wipe of the "oiliness", then start rubbing the residue off. It will sort of peel off in bits and takes away a layer of dead skin with it...rinse and wash. Worked great, my skin felt so clean and so smooth.

Now, if you use it on a regular basis (daily at first, less afterwards) it will slowly take away all those dead skin cells that build up. Any blemishes hiding under all this dead skin will come to the surface, heal and go away. As I am cursed with a few blemishes that never quite go away, just keep reappearing in the same spots, this is something good.

Regular users also say that any small past acne scars they had have also faded.

Sensitive skin people have been using it with positive results as well.

I don't think reg mayo will work, there's way less vinegar in it. Would hm salad dressing work? Maybe, I don't know.
