I've been interested in this product for a while, but I was hesitant to buy it because I was worried it would make my face look flashy and shiny, something that doesn't seem appropriate for my age... but after reading other people's reviews, I tried applying it to the tops of my cheeks after foundation and before blush and face powder. It's subtle, but it gives a nice, intense glow from within. I'm glad I decided to buy it. I'll definitely be buying it again.
