I really wanted to like it.
It came highly recommended by two employees at Sephora but it sure didn’t work out for me. It was clumpy, flakey and hard to remove. I have a good waterproof eye makeup remover too. I was specifically hoping to find something that wasn’t super hard to remove and was promised this was the mascara for me. Not so much:(

Not ysl dupe
This is not smudge proof but it isn’t a horrible product. Definitely going back to ysl waterproof.

Must have in everyone’s routine
Makes my lashes look so long and thick , it doesn’t flake which is amazing because it’s hard for me to find a mascara that doesn’t do this and keeps my lashes curled all day.

Bomb Proof, LITERALLY
Bought this mascara for work, as I typically work long, strange hours and don't have time to touch up my makeup, especially mascara. I work in a customer facing job with often rude clients so I needed my mascara to be BOMB PROOF.
I did not mean literally.
While my lashes looked curled, voluminous, and fantastic, the problems began to arise when I rubbed my eyes unconsciously when I got home. My lashes felt FAKE. When I went to remove the mascara with my tried and true oil cleanser that has gotten face paint, oil paint, and blue food coloring off my skin before with no irritation, I was mortified to realize that the mascara was NOT BUDGING. In fact, my lashes were even STIFFER. I tried with my cleanser for about 5 minutes to get this off before I broke out the coconut oil. Also didn't work. I tried my regular cleanser, nothing. Olive oil, nothing. I cried, actual tears. Nothing. This mascara is for war veterans and anyone addicted to watching sad movies about dogs.
Eventually, I coated a lash separator in coconut oil balm and just... pried the remaining goop off. My eyes were red, raw, and my vision was milky from all the rubbing and product.
Beautiful product. Be prepared to SCRUB though.

Not at all waterproof not even a little
DO NOT BUY. I honestly don't understand what happened with this mascara but it is not even slightly waterproof. At the end of my gym workout yesterday I was so embarrassed when I went to use the washroom and all the mascara was around my eyes. No swimming or water involved. It may be that my tube was defective but I am tossing it. I would return it but I am not often in a mall. Don't waste your money.

Suggested Usage: -Place the mascara wand at the base of your lashes. Spread upwards in a gentle zigzag motion to load lashes with formula. -Repeat along the entire length of your lashes, from the inner to the outer corner. -Alternate between short and long fibers to lengthen, curl, and separate. -What’s the best way to remove mascara from your lashes without damaging them? Simply apply a few drops of SEPHORA COLLECTION Waterproof Eye Makeup Remover (sold separately) to a cotton pad. Press the moist cotton pad against the lashes for a few seconds to soften the mascara. Remove the largest amounts of mascara with small taps and pinches, without rubbing.
