Jennifer Carpenter has a condition known as Bell's Palsy.
Bell's Palsy is a paralysis or weakness of the muscles on one side of your face. Damage to the facial nerve that controls muscles on one side of the face causes that side of your face to droop.
The nerve damage may also affect your sense of taste and how you make tears and saliva. This condition comes on suddenly, often overnight, and usually gets better on its own within a few weeks. Learn more about this medical condition on WebMD.com.
Carpenter is best known for her role as Debra Morgan, Dexter Morgan's sister, on Showtime's hit show, Dexter. Carpenter was married to her Dexter costar, Michael C. Hall in 2009, but they divorced last year.
