I am using the glo mineral eye shadow from quite a long time and I never tried to find that what it is made up of. But now when my eyelashes are getting thin and the upper part of my eyes is becoming darker day by day I want to know that is my mineral eye shadow a reason behind it. I want to know that is mineral eye shadow really made up of minerals or does it contain any kind of chemical that can lead to the above problem. If so then what can I do to prevent these kinds of problems?
