If you read the description on this product it is extremely accurate. The length this product creates is nuts. Other mascaras I have used that have created this length tend to flake during the day. This product does not do that. I was very impressed by this. Only negative with this is that when you remove your makeup it takes a lot to get rid of all the black mascara flakes. I did find it took several layers to get the fullness and length I like.
I would say the only thing that this mascara doesn't do is add volume. It is better at creating length.
I'm always on the lookout for new mascaras that are waterproof and lengthening. The description for this macara and the packaging both appealed to me so I was very excited to get on this trial team! The brush comes with short plastic/silicone bristles, which I don't really like because I prefer longer bristles that make it easier to separate each individual eyelash and coat them fully. And just as I expected, it clumped up slightly when I tried to apply using the brush. In the end I had to use a clean spoolie to brush out my lashes after each coat of mascara which was a bit inconvenient. It definitely helped define my lashes more and gave more volume, but I had to recurl my lashes (which are normally stick straight) after applying 2 coats. The product inside the tube does feel quite liquidy right now since it's new and from past experience old mascara that's had time to become 'thicker' seems to hold up my lashes better. It survived my errand day well and I wore it for a good full day plus a workout with minimal undereye smudging. Granted, towards the end of the day it was basically gone and my eyelashes had flopped but miraculously there was no black smudges. Removal with a biphase eye makeup remover was relatively effortless and after I washed my face with cleanser it was all gone,
Overall I'd recommend this for it's 0 flakiness and 0 smudging, and it would be good if you naturally have curly lashes that just need a bit of extra oomph. But not quite holy grail for people with flat and droopy lashes, also it's got a little bit of clumping which isn't a huge deal breaker.
