Great eyelashes don't just happen overnight. That's why it's important to note that Latisse (bimatoprost ophthalmic solution) 0.03% works gradually and remarkably - starting at 4 weeks with full results after 16 weeks. Once you begin treatment, you could start to see results in as little as 4 weeks, but you must continue applying the topical treatment each night and follow the directions for best results. Remember results are gradual over time. Your eyelashes will experience real measurable growth. Latisse works from the inside out. As the treatment progresses, you'll begin to see changes in length, thickness and darkness gradually. After week 16, you'll see the full effect of Latisse - and so will others.

In the clinical study, 78% had a significant increase in overall eyelash prominence (including elements of length, fullness, and darkness) at week 16.
