I purchased the RMS face oil, as well as the "un-coverup", and as was the case with the first two purchases, this luminzer didn't dissappoint! My skin tends to "overreact" to most products, anything whose base isn't water, or essential oils, etc. That's why I chose to try several things from this brand. The luminzer glides on like a thin butter, and just gives enough "glow"; nothing sparkly or makeup-like. I love to run it up the top of my cheek bones, down the center of my nose, and cupid's bow. It also has great staying power. I used this in conjuntion with the un-coverup, which I use for under-eye circles. I apply with a small brush, and it works GREAT. A little luminzer in the corner of the eyes on top of the un-cover up does the trick. Is so smooth and creamy, but LIGHT. Doesn't settle into fine lines. Washes off clean with no need for makeup remover.
