How do I… look my age..?

I’ve been told a lot that I don’t “look my age” and that I look 12… I’m 19 you guys. I don’t know what to do/add to myself make me look more my age. I used to have lash extensions, and I think I want them again but they would fall out everywhere and it was just irritating when they would sometimes all fall out at once if i slept weird…

P.S I don’t wear makeup and I honestly don’t want anything other than mascara… Idk why but my skin breaks out too easily and makeup takes me forever 🥹 but i give it to all the ladies to can do a full face everyday AND have clear skin🫡🫡
