When I first started wearing this mascara it was great and worked fine, then after a month or so the mascara started clumping on my eyelashes and became dry, I don't suggest purchasing this mascara.

I also received Sephora's Atomic Mascara as apart of my Sephora Birthday Gift for being a Beauty Member and I was extremely impressed with the product. I'm very picky about mascara and after years of trials and finally falling loyal to L'Oreal Voluminous I would cheat or switch my mascara routine to continue using Sephora's Atomic Mascara. I love the brush, the application and the black full, full, full lashes I'm left with. I love intense lashes for evening and this mascara lets me continue to add more until they are as thick and intense as I want after work :)

I received this mascara in a sample size, standard black, as part of Sephora's birthday gift for being a Beauty member. I love it! It doesn't clump, smudge or flake and easily comes off with remover. It really separates and looks very natural on. I will definitely take in my sample and get a full size one.

I am very picky when it comes to mascara. I wear it everyday so certain aspects of it are important to me. My eyes tend to water in the sun, so, the mascara can't be running down my cheeks. I also like mascara to be thick in consistency. And, the brush is very important because I don't need my eyelashes clumping together.
I do think that Sephora's Atomic Volume mascara is a little pricey at $15. BUT, I love it and find it totally worth it. Once the mascara is on my eyelashes, it stays put. The tubular brush separates my lashes ...so no clumping. And the formula is thick and makes my eyelashes nice and thick too! Yay for this mascara!
