Lips: run a toothbrush over flakey skin to smooth it out

Hands: Clean with antibacterial wipes instead of soap as that can be very drying

Scalp: Massage scalp once a week with olive oil and a crushed aspirin mixed in it. this adds salicylic acid to help exfoliate dead cells

Arms: Try an at home microdermabrasian kit to get rid of bumps

Back: Try a dry oil body spray to reach that hard area, or put lotion inside of a back scrubber (the ones with the long handles to reach the back)

Heels: Rub in a lactic acid lotion and then a rich foot cream, twice a day if possible.

Body: Shower at night instead of the morning. It may tempt you less to use scalding hot drying water.
