I have used shade 21 of this foundation for about 6 months, and I love the formula - it provides great coverage and is very moisturizing and soothing on my super dry, sensitive skin. (Although for those with a sensitive nose, be aware that it smells like sunscreen.)As much as I like the formula, though, shade 21 is too dark and too grey for my skin, so I ordered the new shade: 13 (neutral beige). I just received the new shade so I can't yet speak to how it wears/ feels in comparison to shade 21,See full review
