Is it Safe to Line the Insides of My Eyelids?

Question: "I like the look of eyeliner on the inner rims of my eyes -- but is it safe? "

Answer: No. "Lining the inner rims blocks the tear glands that hydrate eyes," says Anne Sumers, M.D., a spokesperson for the American Academy of Ophthamology. Over time, the practice can lead to irritation, lash loss, painful swelling (sties) or a more serious infection. To create a similar effect, gently line right at the lashes, concentrating on outer corners. Try Clarins Eye Shimmer Pencil, $18; Physicians Formula Eye Definer Automatic Eye Pencil, $5.25.
