I really don't like makeup, I feel like it gives people who don't wear it more reasons to feel insecure and uncomfortable with how they look. The people who don't cake their faces in makeup shouldn't have to feel insecure or uncomfortable because people around them hide their blemishes and their own insecurities with concealer and cover up.
But makeup clearly helps other people to feel better about themselves so it can't be all bad. Make up can help people boost their confidence by hiding their dark marks and blemishes. If makeup helps you go ahead and wear it be confident in yourself, if you don't like wearing makeup don't but don't let the ones who do make you think less of yourself.
