Choose your foundation. If you already have flawless skin (no freckles, blemishes, discoloration, or uneven tone) you should use a tinted moisturizer. This will add a bit of color without looking cake-like. If you want to cover a bit more, use a foundation.This is one product that you should splurge on. To get the right shade apply some near your cheek in natural daylight and make sure to test a bunch of them to find the right one for you. Ask one of the professionals in the store to help you find the right color.
