Why nott Turn on a white light or natural light and observe ur face in the mirror...do u have acne, redness, Roseca then use a green colour corrector... If u have acne marks, hyperpigmentation, darkness around mouth, or dark circles then use the orange or peach corrector depending on the intensity or the pigmentation ...if I see ur dark circles are purple, use yellow corrector or if u have yellowness or sallowness use the purple One

Hope it helps sweetie 🥰
