I was reluctant at first, but have been absolutely thrilled with the results. People noticed without my saying anything. One friend thought I had false lashes on. It took at least 3 months to see full results. At first, it seems they grew in length, and then after awhile longer, they filled in. At first, I noticed a slight burning sensation, but that went away after about a month of use. I am very happy with the product. I don't even have to use an eyelash curler any longer. It's refreshing to purchase something that actually lived up to its claims. I will definitely be continuing to use this product.
