I have used three bottles (almost) of Latisse. I don't care what the doctors say on Real Self...Latisse does cause skin to darken in some individuals. I use a very thin brush and only apply it on every third night on the lash line only sparingly...I still look like I have two black eyes. I hate the idea of stopping it because I have a bald spot on lash line without it. I wonder if those lasers that remove freckles and purple pigmentation could remove this?
