Michelle Obama and Jennifer Aniston have more in common than their fashion icon status — they both have flawless and impressively defined arms. "Arms require a lot of maintenance, and I'm sure these women put a lot of energy into their arms," says Dr. Fusco.
Keratosis pilaris, a condition in which excess dead skin clogs follicles and causes red bumps on the backs of the arms, plagues 40 percent of adults (even some celebs) and can make healthy skin look flawed. The condition is not curable but can be minimized. Exfoliate the area first, then use a moisturizer with pore-cleansing ingredients like urea and AHAs (alpha hydroxyl acids), or see your doctor for more aggressive treatments.
Elbows tend to look dark and flaky, but Jennifer and Michelle likely keep theirs soft with exfoliation and lotions with rich emollients like petroleum, ceramides, or glycerin, which locks moisture into the skin.
