They definitely make a difference! Well, they do for mine anyways. I've used a few different ones (Clinique, Revlon, and Sephora). The best one? Sephora's! I got it in pink - I was feeling girly
If your lashes are naturally a little straight, curling them makes a huge difference before applying mascara. Some people are blessed with naturally curled lashes, but most of us are unfortunately not. Curl them 3 times: At the lash bed, in the middle, and the tips. Curling them 3 times gives them a more natural curl vs. curling them once at the lash bed and having them end up at a 90 degree angle...
