a client of ours told us about the body buddy, a tool to do the back-product-application-shimmy which has non-absorbable material to distribute those corrective acne serums and sunscreens to the back. we haven't actually tried it out, but it sounds like a good idea. and at $25, it seems like a good investment.
anyone out there who has tried this thing, or wants to be a guinea pig?! :)
