I was not satisfied with this product

This is a serum that is to be applied to the lash line and eyebrows to encourage growth. It's easier to apply than I thought & goes on the lash line much the way liquid eyeliner does. Because it is a slight shade of brown, when it dries, a user can tell that it's there, but it's not overly noticeable on the lash line. For the brows, it's best to blot it (or comb it in while it's damp) to eliminate any visible flaking. The results that I got after just 11 days was amazing. The tube is good for up to 4 months supply, so I was really pleased with the fast results. The best thing to like (other than the results) is that any growth remains even when the supply is exhausted. Since there is a 365-day guarantee in place, it's a great product to try out. I got to try this product for free, but I will most likely purchase it as gift for friends.
