Clarins Fix' Mascara ($18) is a sealant top coat for your eyelashes. It's not a regular mascara; instead, it transforms any mascara that you already have into a waterproof mascara. Brilliant!
It is made from ultra-fine waxes and hectorite clay crystals that have been formulated into a transparent gel. The gel then binds to the lashes, making them waterproof and even smudge-proof. You can also use it alone to strengthen, soften and add a fantastically shiny luster to your lashes. Just one coat, and you can cry if you want to!
