I've been using this product for about 2 weeks already and I really like it! I was looking for a product that can help strengthen my lashes and this is definitely the product I needed! I was actually surprised since the results were pretty immediate, after putting it on a couple of hours before sleep the following day I didn't have any lash fall out! I was super excited about this since almost every day I would notice at least one lash fall out! I'm confident this product works since on the days I forget to use it, I notice lash fall outs! So this product has now become a part of my daily routine!!!
