Latisse, known generically as bimatoprost ophthalmic solution, is primarily prescribed to enhance eyelash growth. A documented side effect is the potential for increased brown pigmentation in the iris, particularly in individuals with lighter colored eyes. This alteration in iris color is typically gradual and may be more noticeable in the area where the solution is applied.
While not its intended purpose, this pigmentation shift has become a point of interest for some individuals. The change can be permanent, making it a significant consideration for those using or contemplating the use of bimatoprost. Understanding the mechanism behind this side effect involves exploring melanocyte stimulation within the eye. Historically, prostaglandin analogs, the class of medications to which bimatoprost belongs, were initially developed for other ophthalmological purposes, with the cosmetic effect on eyelashes discovered later.
