Latisse is a FDA-approved product that improves the length and thickness of your eyelashes.  It is easily applied once a day, although some people may be able to maintain with just 3 times a week application once they have achieved their desired lash length.  One kit usually lasts 2-3 months, and is generally safe for all eye colors.  Hazel eyed individuals have a very low risk of darkening of their iris, but this complication is extremely low.  Our patients will often use Latisse to promote brow hair growth as well. Your lashes will appear thicker, darker, and longer in about 1 month of consistent use, but 4 months is needed for optimal results.
