Latisse is a FDA-approved product that improves the length, thickness and darkness of the eyelashes. An applicator is removed from its tray and then, holding the sterile applicator horizontally, one drop of the Latisse solution is placed on the area of the applicator closest to the tip (but not on the tip). Immediately, the applicator is drawn carefully along the skin at the base of the upper eyelashes (where the eyelashes meet the skin) while going from the inner part of the lash line to the outer part. Any excess solution beyond the eyelid is blotted with a tissue.
