Latisse

Latisse is the only FDA approved product clinically proven to make lashes darker, longer, and thicker.  The best way to apply is to uncap the bottle, place one drop of the solution in the cap, and dip the enclosed brush into the liquid to dampen it.  Then, apply a thin line along the upper lash line as you would eyeliner.  It is best to apply eye cream prior to use to prevent eyelid skin irritation.  Maximal results are seen at 16 weeks, but results begin to appear after the first month.  Once you have achieved the desired length and fullness of your lashes, you can reduce to twice weekly maintenance treatment.  This also works beautifully to promote regrowth of sparse brows.
