LATISSE® is a prescription treatment for hypotrichosis (inadequate or not enough lashes) to grow eyelashes longer, fuller, and darker. Great eyelashes don't just happen overnight. That's why it's important to note that LATISSE® solution works gradually and remarkably — with full results at week 16. Once you begin, you must continue applying the topical solution each night and follow the directions for best results. If you stop using LATISSE® at any time, your eyelashes will return to their previous appearance over several weeks to months.
The LATISSE® clinical study was conducted at 16 sites across the country and included 278 participants of varying ages (22 to 78). The study tested LATISSE® solution and a vehicle (or placebo), which was LATISEE® without its active ingredient. Neither patients nor clinical investigators knew which group received what treatment. By week 16, the results showed that 78% (107/137) of participants experienced a significant increase in overall eyelash prominence (including elements of length, fullness, and darkness), compared to 18% (26/141) for the vehicle group.
Clinical trial results showed lashes were:
- 25% longer (2% for vehicle)
- 106% fuller (12% for vehicle)
- 18% darker (3% for vehicle)
