Yes, our eyes are too deliberate to most of chemical substances at a limited level. Eye makeup are always associated with eyes concealer, eyeliner, eyeshadow and highlighter, sometimes the use of fake eyelashes and eyelash glue. Both of them may cause contact dermatitis based on your personal sensitivity. As we all know, all the cosmetics contain some chemical substance having potential health hazards. The incorrect ways to wear and the incomplete makeup discharge will definitely lead to tiny chemicals residue. As a result of long time accumulation, your eyes will be irritated, and then result in some more serious eye diseases, like conjunctivitis. I use the cosmetic items everyday. What I focus most must be the quality of the items, and then the complete make up removal by special makeup remover. You can never expect that a poor product will have a protective property.
