My wife is tripping out about me wearing makeup. Any suggestions on how to respond?

I got more and more into makeup over the last few years. I've always had some acne and scars and now am starting to notice my aging. The makeup isn't colorful, but it's obviously noticeable. My wife is probably embarrassed about it and keeps telling me I don't need to do it, and to just be confident about myself. I don't want to do the whole "but you do it" thing with her, because she obviously recognizes that. I just don't know how to get her onto my side. Some ideas would be really appreciated.
