Generic Name: bimatoprost ophthalmic solution Company: Allergan, Inc. Latisse is a once-daily prescription treatment applied to the base of the upper eyelashes with a sterile, single-use-per-eye disposable applicator. Latisse users can expect to experience longer, fuller and darker eyelashes in as little as eight weeks, with full results in 16 weeks. To maintain effect, continued treatment with Latisse is required. If use of Latisse is discontinued, eyelashes will gradually return to where they were prior to treatment over a period of weeks to months (average eyelash hair cycle).
