This highlighter really works! I love using it under my eyes - I have very dark circles :(
I am also a make-up artist and I've used it on brides - it truly does reflect light, and conceals those dark under-eye circles (on photos especially!).
It's lightweight, spreads easily and the smooth formula does not cake when covered with powder.
I use this as a final step in my make-up application to make my eyes look young & fresh. Also great for touch-ups.
