If you wear mascara and eyeliner on top of your eyes (eyelids) everyday..can make you eyelashes weaker..doesn't mean they fall out but if they get weak they can..although they will grow back but it takes some time. Try removing it everyday and avoid mascara..that's worse than eyeliner. And I heard that olive oil can make your eyelashes stronger ;) ...you go girl :D good luck!
No, it can't make your eye lashes fall off, but if you wear heavy mascara and don't wash it off it can damage your eye lashes. Of course, your eyelashes do grow back. Foundations don't damage your skin but if you don't take it off at night after a while it can make your skin look old after a while. Just make sure that you give your skin a chance to breathe. Eyeliner doesn't effect you in any way and neither does eyeshadow, but too much eyeliner can irritate your eyes and smudges easily. I wear a lot of make up myself and boy it is magic! I hope this advice helps you.
no they can't you need to wash off your makeup before you go to sleep
No it doesn't make your eyelashes fall off. I wear it every day and mine are fine. Just make sure you wash it off properly
