Over the past 4 weeks I have noticed my lashes get longer, stronger, softer and a lot less lash fallout. My bottom lashes have grown significantly longer and fuller. Since I have not used any other type of Lash Serum I can't say its the best. But I suggest you give this a try for the price. For $6.99 I say give it a go!
I had very few problems with the serum. When you first apply the serum to the lashes, you will get a warm sensation that some may find uncomfortable. Also it will sting if you get it in your eye. Other than that I had no problems.
