I am not a fan of any of the LashBlast mascaras. They just don't do much for me. I've tried the original (meh), and the LashBlast Fusion formula (double meh), but I had to try a mascara that claimed to last 24 hours. Had to.
LashBlast 24 Hour comes in a fat black tube with metallic orange lettering and graphics. It comes in a few shades of black, and I picked up Very Black (as opposed to "Black"). I almost exclusively wear black or the darkest black mascara available. Brown mascaras always look weird to me, and it's super easy for me to tell if the mascara has pigmentation issues, because my lashes are red/blonde.Like the original LashBlast, 24 Hour has one of those massive rubber/silicone spikey wands. I hate them. I knew I hated them when I bought this mascara, and I should've known nothing would change my mind. This surely didn't. It's hard to get the inner and outer corner lashes with these things, because the cone-shaped bristles are microscopically small at the tip, making them more pointless than an icemaker on Antarctica. The pigmentation is somewhat poor, as well. I wore this over a while mascara primer (Lancome's Cils Booster XL), and it usually required 3+ coats to fully cover the primer. This subsequently caused some clumping, but it was easily brushed out with a metal lash comb. Without primer, I still needed multiple coats to fully cover my lashes.
That said, it lasted all day without flaking or smudging. Did I get "a blast of lush, volumized lashes," as Cover Girl claims? No. I got slightly volumized lashes, with a touch of extra length. Oh, and a bit of aggravation when it came time to remove this stuff. I've been using Clinique's Take of the Day Balm, and 24 Hour lasts through that, plus normal face washing. I have to use an eye makeup remover, then the balm, and then wash my face. That's a lot of steps. I don't really like to spend that much time and energy on my lashes, because I really don't want to pull them out during the process of getting them clean.
If you need a mascara that lasts forever, 24 Hour is for you. If you want a mascara that lasts all day and is easily removed, however, don't bother with this one.
