Latisse is an FDA-approved eyelash growth treatment that enables you to grow your own lashes 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 continue applying the topical solution each night. 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 — and so will others. After that, you can talk to your doctor about ongoing use.
