In my experience, eyeliner has been one of the hardest makeup products to use.  There’s so much precision involved and it always seems that my eyeliner ends up on my cheeks during these hot and humid months of summer.  Although I’ve mastered the art of applying my eyeliner every morning, it takes me a lot of concentration and scrutiny for me to get it just right.  However, since I’ve discovered Bobbi Brown Long-wear Gel Eyeliner, now I spend only a few seconds to apply my eyeliner.  It’s waterproof and it comes in many different colors.  At $21, it is definitely not cheap, but completely worth the fact that it decreases the time you need to spend on getting the perfect eyes every morning when you’re in a rush.  Not to mention, at the end of the night, a lot of times, it is rather difficult to take waterproof eyeliner off even with the best eye makeup remover, but Bobbi Brown comes off hassle-free.
