Make Friends with Vaseline
Jokes aside, Vaseline can be your best friend when it comes to soothing cracked knuckles. "Cracked skin is no different than getting a scrape from a fall," says dermatologist Caroline Chang, M.D., in Providence, R.I. "It is an open wound. There's no way to make it heal faster, but covering it with Vaseline ($6; walmart.com) will prevent skin from hardening and then re-cracking every time you bend your fingers." Keep small tubes of the stuff near your kitchen and bathroom sink, and in your office for easy re-application throughout the day.
