Does Latisse change eye color?

No, Latisse will not change the actual color of your eye, however, it may result in permanent staining, which could be especially visible in those with light eyes.

There is no evidence to
suggest that Latisse will change your eye color. Several million prescriptions
for Latisse have been filled with no confirmed reports of iris pigmentation changes. It is considered a very rare side effect when this medication is used as
a glaucoma medication when it is applied directly on the
surface of the eyes. Side effects from the initial studies
showed less than 4 percent of patients experienced redness, irritation and
itching of the upper eyelid, which was reversed upon discontinuation. The
eye is exposed to only a very small amount of
Latisse when it is properly applied as directed to the upper eyelid margin
using the supplied applicator. This has been demonstrated by applying a colored
dye to the eyelid margin and watching its migration.

Latisse does include the same ingredient but it is not applied IN the eye. It goes on the lash line only. There are no reports of Latisse causing eye color change when it's used cosmetically on the lid line, with about 4 million kits sold. The ingredient actually doesn't make blue eyes turn brown either. It darkens the flecks of color in hazel or green eyes WHEN APPLIED IN THE EYES. "This answer has been solicited without seeing this patient and
