All women know that so-called waterproof mascara is not always waterproof. That’s why Lash Genius by Anastasia Beverly Hills is such a welcome new product. Combining silicone resin with high-melting-point wax, this clear topcoat waterproofs any mascara and refreshes and protects your lashes without irritating your eyes, drying out lashes or clumping. And it lasts and lasts — just in time for swim season.
