I went to Sephora today to grab some more Diorshow Waterproof mascara, and the girl at the counter was like "have you tried --whatever," the other Dior one, something about it being extra black and non-waterproof. Well she continued to say that waterproof is so bad for your eyelashes, they'll fall out and be thinner and not as nice. I have been using like $7 waterproof mascara basically since I was like 13 years old, and have only within the past 8 months started wearing the Diorshow waterproof which is better. Is it really damaging? I mean honestly, I don't seem to have anything wrong with mine... but now I feel like maybe I should have gotten the other stuff? But whatever... just curious because I've never heard of that. I've even heard of needing to make sure it's not on my lashes when I sleep, but I just wear it to bed. I mean I'm almost 22 and I've been doing this since 13 so... nearly a decade when you think about it!
