I think my first advice would be to get a feel for what you’re comfortable with! Things like whether having products on your skin or eyes bothers you at all, does having skincare on make you sweat more or does having eyeliner or mascara on irritate your eyes! It’s the one thing i base my makeup on every time! The products i buy and what i do each time is how well my face handles it in terms of comfort! Look for products that FEEL the best for you not just look.
And second is practice! I HATE trying something new right when ive got somewhere to go bc i often mess it up lol so i always practice smth before doing it on a regular going somewhere. Pick an evening and test some stuff out, have fun and learn what you like and dont.
For brands i personally use mostly nyx, maybelline or just random drugstore stuff. It takes a while to decide what works best for your face yk a little trial and error.
Best of luck to you and i hope this was helpful!
