I usually use it every time I go to the beach, it's very good when it gets in the sea water and doesn't smudge around the eyes, when I use it my eyelashes look much thicker and black more. I like it

This is the best mascara ever! It’s the only waterproof mascara I have tried that really is waterproof AND still looks good. It’s lengthening and voluminizing!

While the mascara can stay on your lashes even for 48h, it doesn't mean it'll look good. For me, the wand made them too clumpy and stiff and made it awkward to apply without accidentally touching your skin with the wider bristles. It is indeed waterproof and tested on the beach and at the pool. Wouldn't buy again.
