SEINT's 3D Foundation is different than any other foundation you've ever used.
Four different colors (highlight+contour+blush+illuminator), work together on your face to create a scuplted "lit from within glow". You'll get buildable coverage, color correction, brightening, and dimension within ONE layer of makeup.
