If you don't take ..

I've heard that it can a) age your skin and b) weaken or make your eyelashes fall off. But I went through a period of 6 monthes where I just got waaaaay too lazy to take of my mascara and it seemed like I had more eyelashes and they didn't fall off as much. Does anyone know for sure!? If they do make them brittle, would putting on one of those conditioning mascaras help to get rid of that problem?

i am the same as you, we have a bad habit, anyways, they do break off a little. i never noticed any big difference.

i think the only way to make sure they dont become brittle is so take off the mascara before bed

If I were you, I would try one of those conditioning mascaras.

Also, remember to throw out your mascara after six months. If you use mascara after six months, you can get an infection . Mascara is not as clean and durable as other makeup items.
