Another thing Cline and I have in common: we're terrified of our eyelashes falling out, especially from an overuse of mascara. I already wear a nightly lash serum (my usual is the RevitaLash Advanced Eyelash Conditioner), but I was intrigued by her more affordable option that I found at Target. The DHC Eyelash Tonic ($14) is easy to apply — it comes with a traditional mascara wand — and doesn't irritate my eyes or skin. Although I think I'll be sticking with my original conditioner, the Eyelash Tonic is comfortable to wear during the daytime and works just as well underneath as layer of mascara.
