Is wearing makeup or eye mascara harmful to my eyes?
Eye Makeup and mascara aren’t necessarily harmful to the eyes when used properly and disposed of at timely intervals. When looking for eye makeup or mascara, look for hypoallergenic products, I discourage people from wearing their eyeliner or eyeshadow on the inner eyelid or “watermark” area of their eyes, it can clog glands there and cause dryness issues. Consider replacing your products every 3-6 most especially the mascara and eyeliners which are generally applied closer to the lash line. Make sure you remove eye makeup completely before bedtime to ensure less likelihood of infections. Always put your contact lenses in prior to applying makeup and make sure you wash your hands prior to applying any eye makeup.
