It’s not superficial to care about the way you look. There’s nothing wrong with enjoying the time spent on your appearance if that’s part of your self-care. People may use labels such as “vain” or “shallow” to try and keep you in a box, to make you feel small. But those people are usually just insecure themselves. Nobody else gets to tell you what you should or should not care about in terms of your looks. That’s something you get to decide all for yourself.
