There are certain make up manufacturers who only fabricate products for making money and they are very less worried about the product's side effects and all, cause by the time they would get complains, they would have already got their profit and closed the business!
You have to look for the best and well known products that are on the market since a very long time.

Is it possible to get conjunctivitis with eye shadow?
I have always worn eye shadows and I haven’t got any complain with them. You have left me in a terrible state of shock. I have even thought about not to wear eye shadow onwards.

That’s a wise decision of not using mascara. When your eyes will be okay then you can apply as much mascara as you want. Have you consulted a doctor for your eye problem? If you haven’t then be quick to do so because it concerns your eye-the most sensitive part.
