This is a very useful pen of concealer. It takes a few uses to get it going and become familiar with it, as well as to control the amount you release. It is effective, but light, and looks natural. After being diagnosed with dry eye, I immediately went to Clinique for a few basic make-up items, and have been very happy with this, shadow and mascara.
It is a bit confusing that Illuminator is actually a color choice of the Airbrush Concealer, because it feels like its own distinct product. I love it, the blend is lovely and it does exactly what I want, which is to lightly diminish dark circles without feeling or looking like makeup.
