False eyelashes can trap dirt and bacteria, creating irritation and infection. And they can be difficult to remove.
And Actress Kristin Chenoweth wore sunglasses on "Late Show with David Letterman" after her eyelids swelled up. She got what are called eyelash extensions, where single fibers are glued to your individual eyelashes.
The risks of eyelash extensions are not only an allergic reaction to the glue but also erosion of the inner surface of the eyelids. And they can cause permanent damage to your natural lashes.
The Internet promotes even more exotic eyelash enhancements: weaving tiny glass beads onto ultra-thin wire and applying them with an adhesive to your eyelids. It doesn't take an expert to see trouble coming with sharp objects placed so close to the eye.
Consumer Reports says that you are far better off just using mascara to get fuller, thicker lashes. And you should replace mascara every few months, but you don't necessarily need to buy an expensive mascara. A tried-and-true choice is Maybelline Great Lash Mascara for a little more than $6 a tube.
