I don't know why, some kinds of eye shadow and mascara sting my eyes. But they don't sting immediately after application but some hours after that when I'm outside and my eyes just start getting tears and until tears wash my makeup completely, it just doesn't stop. I get teary eyes in cold weather sometimes even without wearing makeup but it is short and doesn't sting. I'm sure one kind of eye shadow always irritates my eyes so I don't use it anymore but recently I bought a new mascara and it seems like it is responsible for my teary eyes.
My question is - is this irritation due to some ingredients in eye makeup? Or can it be because the application brush is contaminated with something? Are there any other possible explanations? And which ingredients are usually irritating? Here in Korea they don't always write the ingredients of colour cosmetics, how can I know?
