While the First Aid Beauty KP Bump Eraser Body Scrub With 10% AHA ($26) is meant for those suffering from keratosis pilaris, it actually can help anyone with dry, rough patches or tiny bumps on the skin, even if it's not from KP. The scrub works like both a chemical peel and a microdermabrasion treatment, as there are glycolic and lactic acids to chemically clean clogged pores, and then pumice beads to buff away the dead skin cells left over.
