Latisse will not cause you to get a sty. It is a sterile solution. It can, however, cause darkening of the skin along the hair follicles of the eyelashes which is harmless. Many people wear eyeliner there anyway and don't care and some don't experience this effect at all.Best of luck to you!Dr. Cayton
Hi caroldonahue,Latisse does not cause styes. However, if your eyelids got irritated and got infected by the bacteria on the skin, this will predispose you to developing styes. Even infected mascara wands can transmit infection from one eye to another.All the best, Justin Harper, M.D.
