RapidLash is effective, affordable, safe (safer than Latisse!), and it doesn’t change the color of the pupil. I haven’t experienced any kind of irritation or discomfort while using this product. It’s a $50 solution you can use on both your eyelashes and brows and it’s so easy to incorporate into your nightly routine. I’ve been using this product for a week and I’m already noticing a difference! My lashes are longer, and the lash line even appears fuller.
