hey, me and my sister both have sensitive eyes. if we wear some mascara our eyes will like hurt and we get bad head-aches :P But we both wear lots of eye liners.
we use rimmel mainly. its always been good, we've never had any reaction to it and its actualy very good quality :)
and my sister has sensitive skin all over and has (spelling ?!?!) echma but we put the eyeliner on her arm to try it and she had no reacion too it at all :)
