When I heard that a 24 hour version of CoverGirl's LashBlast mascara was going to be released, I admit I was a little bit.... perturbed? Why, oh mascara gods, hadn't this been released years ago? Like maybe.... 2001? When I first started taking overnight call as a medical student? That was in the pre-80 hour work week days (why yes, the hours are federally mandated to not exceed 80 hours now. Which sounds like a lot until you hear that I generally worked well over 100 hours a week as the med student and the residents worked even more.) Anyways, by the end of a 36 hour shift, I looked like a hot mess.
So, this mascara probably wouldn't have survived those 36 hour shifts (it is labelled 24 hours) but it would have been closer than many other mascaras!
To me, this mascara is similar to LashBlast Fusion. It lengthens. It volumizes. It helps maintain curl. Except it just does it for a really long time. At the end of the day (these pics are after about 17 hours) things look almost as good as they did that morning, with no smudges or flakes. I haven't tested this mascara for a full 24 hours (I no longer take overnight in hospital call), but if I did I have a feeling that it would live up to the claims.
I will say that this mascara is a little harder than other "normal" mascaras to remove. It isn't in the ballpark of a waterproof mascara, but it definitely requires a good eye makeup remover and a little scrubbing to fully remove it. I think it is worth it!
