Ive been using Latisse for a year and love the results. I had little nubs for eyelashes and even those were very very light blonde. Now they are longer, thicker and darker.I discovered this about the brushes they send with the package. All those brushes are unnecessary and a pain. So i thinned out the bristles on a few of them and brought them to a chiseled tip. Next, I found an old tiny mirror left from some eyeshadow. I put one drop on the mirror, roll the brush in it until its soaked up. One drop is enough for both eyes and so my expensive Latisse lasts longer and does the job perfectly.
