This mascara does exactly what it's advertised to do: it completely transforms my eyelashes and makes them look so glam! I have short, coarse eyelashes that tend to droop no matter what I do, but you wouldn't know that whenever I use this mascara. This mascara has a super nifty and highly effective brush that does a great job of combing my lashes, lifting each lash upwards (making them appear longer) and giving each a substantial coat of product. The brush is also thin enough to sufficiently coat the thinner bottom lashes with mascara. The formula is thick so it makes my lashes look voluminous, but it never gets clumpy. The formula also is very strong, ensuring that my lashes hold their curl. I always buy the waterproof version of this mascara since I find that waterproof formulas tend to hold curls better, and this mascara really is waterproof. My mascara never runs or gets flaky, even when I'm out all night on the town. This product is a great value for the money, and whenever I use it, I feel like I'm wearing falsies! A must buy!
