I wear contact lenses and by force of habit, I blink a lot, causing my mascara to transfer onto the skin under my eyes. By midday, I have black bags under my eyes. Is this something I can change?

I recommend to use waterproof mascara for your problem, and be sure to get waterproof eye makeup remover too. If you are getting this from the drugstore, then try Covergirl Professional Waterproof Mascara, Almay (pink bottle) eyemakeup remover, and cotton balls. If you are going to the department store, get Diorshow Waterproof Mascara, Clinique (purple bottle) eyemakeup remover, and Shiseido makeup remover pads.
