LATISSE® is an FDA-approved treatment to grow eyelashes for people with inadequate or not enough lashes. Latisse is actually a version of a glaucoma drug in eye drop form called bimatoprost (brand name Lumigan, manufacturer Allergan, Inc.), in use since FDA approval in 2001. During that period, eye doctors and their glaucoma patients noticed the hair growth side effect, with longer, lusher eyelashes appearing over time.
