This is my 4th time purchasing it I think can never get over of this 

Went through 2 full scale crying sessions and this kept my non waterproof mascara from moving or smudging or doing anything it shouldn't. Definitely works for waterproofing mascaras.However, it did look like I had eyelash glue stuck onto my lashes. It forms like a clear coating. The tip of my lashes hooked over and hung down.It was a disaster to get off, but I suppose when it is as waterproof as this is, it won't just wipe off. So that's understandable.

I'm really quite impressed with this product! It works well to keep any mascara waterproof! It does take alittle more effort to remove at the end of the day but I like how effective it is! 👌

I only can use waterproof mascara, and this topcoat make the job. However, I need to brush my lashes after apply the product, otherwise my lashes stick together.

I use it as a primer before a put on my mascara, not after. It really helps any not waterproof mascara to become waterproof and to hold the curl. I also use it on my eyebrows to get them in place . Be gentle though, because if you overdo it it became a crusty mess. But if you do it with a light hand it’s a genius product. And you have to remove your mascara with a really good remover. I’d have not tested to do it the ”right” way so I can’t answer how it works if you do it how you supposed to do.
