Latisse contains Bimatoprost topical solution. Like many things in Medicine, the eyelash growing properties of Bimatoprost was an incidental finding in the treatment of Glaucoma.
Latisse is applied along the upper eyelid nightly. It is extremely safe and never causes discolouration of the Iris (coloured part of the eye). It may cause slight irritation on the first few days of use, but this is generally very short-lived. On occasion it may cause slight discoloration of the border of the upper eyelid; but this is actually an attractive benefit.
