Will Benefit's New Roller Lash Mascara curl your eyelashes? Yes. Will it lengthen your eyelashes? Yes. Will it add volume to your eyelashes? Yes. I am very impressed with this mascara, but there are a couple of things you need to know before trying it. ONE COAT is all you need! I applied two coats in the picture below, but since using it more I now know I should apply only one coat. If you double or triple dip (If you apply this mascara 2-3 or more times) , you're in for a clumpy mess my friends. Your lashes will start grouping and clumping together. Also, this mascara dries super fast! So swipe your inner lashes. Swipe your outer lashes. Brush right to left your bottom lashes. Finally, there's a slight stickiness to it when you initially apply it (guess it's the formula) but it dissipates once dried. Your eyelashes can bend and are not hard. Also, very little fall out. Those are my thoughts! I will be reviewing some of Benefit's older mascaras (They're Real and Bad Gal Lash) to see how they compare to this one. Just curious :) Have you tried any of Benefit's mascaras? Let me know your thoughts.
