I am terribly picky about make-up. Mascara especially being a red-head and needed the lash color!
One weekend at the beach I left my mascara at home. We were staying at a resort and I went down there and bought Blinc from the salon. I am now a life long Blinc user.
It really doesn't come off unless you apply water. Even if you just swim for a minute it stays on.
Only down fall is when I wash my face, it leaves little black tubes on my wash cloths and in my sink/shower.
