I have been using this serum for about 3.5 months now and can confirm it is one of the best things I have ever bought. I naturally have very short and straight lashes, but this serum has made them much longer, healthier and also more curled up!! It took 3 months to show results for me and I almost wanted to quit but patience here is so worth it. I have never been so happy with my lashes and my confidence went up so much. Definitely worth the hype and price, I am in love!
