hey guys ! recently i’ve been getting more into makeup and finding my style. i’m still young so i’m not exactly sure how to do makeup, i would REALLY appreciate if someone let me know how i can find my foundation shade ? i just need it to cover some acne, but i don’t wanna just guess and get the wrong shade. so how can i find my foundation and concealer shade ? thank you sm if you answered !!
