To young to wear makeup?

I am younger and I love to put on makeup but I feel self conscious because most people that wear it are older... my mom lets me but I just feel weird. I love doing it though but I don’t want people to think I don’t love myself and that’s why I wear it. I just think of it as art not beauty 🤷🏽‍♀️ but not everyone knows that. I want to gain enough self confidence to wear bright eyeshadow in public without running to the nearest bathroom and rubbing it off. Any tips? Thx!❤️
