NO CLUE

Ok so I watch makeup videos ALL the time on Instagram , Youtube , etc . So ik how to apply it but I dont't know what exactly to go buy like I just want a regular everyday face not a "beat" face so what kind of products should I get ? Oh an I'm a brownskin and it's hard finding a shade that matches so what are some good black girl make ups or make up with various shades 🤔.
