Query: Very lengthening. Only gets a little clumpy after a month or two.

My mom introduced me and my sisters to this marcara. And now we are all hooked.I'm an esthetician and I wish they had a waterproof version (the only reason it's 4 stars) since waterproof mascaras are damaging to remove. I have a pretty decent makeup remover but it still takes a little too much effort to get completely off.Despite that it totally lengthens your lashes and seems to help with their growth as well! Great product!
