Mascara is a make-up essential and I seem to be constantly trying out new ones in a quest to find one that performs. I've gone both the high end and drugstore routes and while Diorshow is wonderful, I don't really want to spend $$ on a product that I have to discard every 3 months or so. I've worked through the CoverGirl Lash Blast family and Lash Blast 24 HR is the winner in my book. I use the Blue Black and find the coverage and depth of color quite satisfactory. Wear and smudging have always been issues for me with mascara and I'm pleased with this product on both counts. I'm also impressed with it's ability to hold the curl of my stick straight lashes through the day. The brush is rather big with dense bristles so I usually swipe it with a tissue to prevent it from clumping. I'd say the formulation is close to Lash Blast Fusion in that it delivers length and volume though I do think it fares slightly better on the latter and separation is actually pretty good. 24 HR is an apt name since it doesn't flake or budge until I take it off. I thought it might be hard to remove but it comes off easily with my Neutrogena Oil-Free Eye Makeup Remover. It's not perfect but it does fulfill my mascara needs and the under $10 price tag is ideal. I'll probably still be on the lookout for the next best thing though. Drugstore.com is currently offering a buy one get one 50% off promo on CoverGirl products with an additional $3 off so I just picked up 2 for $9.73. Have you tried this product? What is your favorite mascara?
