Laura Mercier Grapefruit is a moderately warm-toned, dark coral with a satin finish. It is a permanent blush that retails for $30.00 and contains 0.2 oz.
Grapefruit is a rich, reddish-coral with subtle, warm undertones and warmer, fine, golden micro-shimmer that gave it more of a satiny sheen when applied and buffed out on my skin. The texture was slightly firmer and thinner initially, but it softened up a bit and was easier to pick up on a brush, though a little went a very long way! It was intensely pigmented and was best applied with a fluffier brush and light hand to gently diffuse the color onto cheeks.
The "issue" is the formula is supposed to be buildable from a "diffused, sheer hint of color," and it's not at all sheer or buildable--you have to be very careful just to get more medium coverage out of it. For as bright and as pigmented as it was, it was fairly blendable, though. It stayed on nicely for nine hours before fading a bit.

Blush Colour Infusion is a sheer, buildable, and silky-smooth cheek color that blends seamlessly with skin for the most natural, fresh look. Pure color pigments feel weightless and apply evenly to skin for a healthy-looking flush of color that lasts for up to 10 hours. Infused with micro-fine powders, this next-generation formula can build from a diffused, sheer hint of color to a bold color statement. It’s designed to layer as flawlessly with liquid or powder makeup as it does on bare skin. Shades range from soft neutrals to vivid pops of color, with finishes ranging from matte to a subtle sheen with hidden pearl, to suit a variety of skin tones and skin types.
