BUY at Birchbox

This primer doesn't just play the go-between between slippery skin and finicky foundation. It bridges the gap between skincare and makeup as well, delivering major moisture even as it helps foundation go on more smoothly and last longer. Its potent botanical-based formula locks in moisture all day-with the added benefit of filling in fine lines and diminishing the appearance of pores.
