As I already have fairly long eyelashes, I wondered if I'd see a difference at all. I had my doubts until I reached around week 10. The key to this product is perseverance and I finally saw the reward to my painstaking applications each night.
I began to notice that my lashes were longer, particularly the outer lashes which were a lot longer and more curly. Since this revelation with RapidLash, I haven't needed to reach for my eyelash curlers once, a momentous outcome for someone who was prone to straight lashes which neither curlers or mascara could cure. I also noticed a difference in the length of my inner baby lashes which are usually rather short even with mascara. My fiancé noticed my longer, more fluttery lashes too. Even without mascara the were long and lustrous.
