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
As the treatment progresses, you'll first begin to see changes in length. Then, gradually, you'll notice more thickness and darkness in your lashes. If you're satisfied with your results by week 8, don't stop there. Stick with the treatment. After week 16, you'll see the full effect of LATISSE.
