No, salt does work as a facial scrub. It does not dissolve because it is in a saturated solution (lots of NaCl, very little H2O). It's kind of fun to use because it scrubs for a while and then just disappears when you rinse with water.

Here's an example product:

Working on boats and cars with my dad, we always cleaned up using sugar and dish soap. Never salt! Because it'd make those scraped knuckles sting! :)

Just get the marketing guys to make up something about the stinging letting you know that it's working. ;)

You need to cruise through the skin care center of your local cosmetics/beauty/whatever store. If you put in only enough water to keep things moving, rather than creating an unsaturated solution, sugar and salt work very nicely.

Couple that with the added benefit of being water soluble, cleanup after using the product is especially easy. Scrub and rinse (and gently scrub) until you can't feel the product. It's self-documenting. :-)

Really? Sugar scrubs are so soso very old. They predate the costemtics industry.
