The Ordinary prides itself on its innovative formulas that strip skincare and make-up back to basics, and that is exactly what the Serum foundation does. Designed to offer medium coverage with a lightweight serum feel, it is available in 21 shades with varying undertones. Choose N for neutral, Y for yellow, P for pink and R for Red. For added lustre, three of the 21 shades are available with silver (S) and gold (G) highlights to add a dispersion of metallic pigments to your natural face.
