People regularly ask me if my lashes are real. That's how I know it works. My lashes are so long, I often leave mascara marks under my eyebrows. This product works, but you need to be patient and consistent. I got the best results when I applied it on a clean face every evening and gave it a full 8 weeks. Once they are long enough, then you only need to reapply a couple times a week. It's not a cheap product, but one tube usually lasts me 2-3 months.
