Foundation Primer is a lightweight, creamy, vitamin-rich gel that creates the perfect canvas for makeup application. Available in a convenient trial size, also perfect for travel. Just as a painter primes a canvas, Foundation Primer"the original"was created by Laura Mercier in 1995 to prime the skin. The gel creates an even, invisible layer that acts as a buffer to outside elements and expertly holds foundation. This water-based formula keeps makeup fresh and color-true for hours. Visibly skin smoothing, Foundation Primer is ideal for all skin types.
