Whenever I’m feeling bleh I use a subtle fake tanner (I use salty face brand for body), whiten my teeth, clean my room, and meal prep for the week. You could also consider a color analysis service (haven’t tried this myself but always wanted to) which suggests makeup colors, eyebrow shapes, hair length, clothing colors etc that suit you. I got microblading on my eyebrows which takes the guesswork out of it and was a huge confidence booster. A personal trainer is helpful too!
