Lash Genius from Anastasia Beverly Hills. When I explain this product to you its totally one of those "how is it this hadn't been invented until now?" moments as well.
From Anastasia Beverly Hills: “Waterproof when you want it to be. Lash Genius Clear
Waterproof Topcoat instantly waterproofs, refreshes, and protects any
mascara all day, without the typical drying or clumping. It’s advanced,
lightweight formula glides on smooth, dries quickly, and gives your
lashes a touchably soft lacquer finish that lasts all day.
Dermatologist-tested. Hypoallergenic, Paraben Free, Fragrance Free.”
What it is: A clear, waterproof top coat that transforms ANY mascara you're wearing into a waterproof wonder.
I love this. Its lightweight so it doesn't mess around with my mascara & it doesn't add that weird shine I don't like either. As much as I love eyelash primers, I oh-so rarely use them because I feel like the white is never COMPLETELY covered. Clear. Brilliant.
I have put this to the test with some of my favorite mascaras that aren't waterproof & it definitely held up its end of the bargain! I don't always love waterproof mascaras, sometimes they just don't feel right. Know what I mean? My lashes looked fab morning to night, even through a chick flick or two. Plus, it didn't bother my poor allergy eyes. Impressed? Yes, yes I am.
Where you can get it: I believe this is available at Sephora but since I don't shop there I recommend getting the Lash Genius off the Anastasia Beverly Hills website. Its $21 & worth every penny. Whether you use drugstore mascaras or high-end, I find many waterproof versions just aren't good. This totally saves me touch-ups, money, & lots of frustration. Worth. Every. Penny.
