Latisse (bimatoprost) a topical prescription product from Allergan, is the first and only scientifically proven product approved by the FDA to stimulate eyelashes to grow longer and thicker. It is prescription and therefore only available through physicians. Enhanced eyelash growth is typically seen within 4-8 weeks but may take up to 3 months in certain patients. Once lashes have grown to their desired length reduce applications to 2-3 times per week. This is necessary to maintain your results. If application is discontinued completely eyelashes will begin to shed normally and return to their pretreatment appearance in 2-4 weeks
