How do I choose the right foundation shade for my skin?

To find the right foundation shade, start by identifying your undertone. Cool undertones have pink or bluish hues and work best with foundations labeled cool or pink. Warm undertones appear golden or yellow and suit foundations labeled warm or golden. Neutral undertones have a mix of both and can wear either. Once you know your undertone, test shades by swatching two or three options along your jawline in natural light, not on your wrist or hand. The right shade should disappear into your skin without looking too light, dark, orange, or ashy. Allow it to sit for a few minutes since foundations can oxidize and shift slightly darker after application.
