This illuminator works beautifully with the amazonian clay foundation. It adds a perfect glow to the skin that looks natural and radiant. A little bit goes a long way, just a few dabs and you are good. I used this mixed with my foundation and areas I focus on are my cheek bones and the bridge of my nose. What I love most about this serum is that its free of oil, fragrance, parabens, sulfates, petrochemicals, GMO's, and synthetic dyes!
