Brown Eyes Turning Hazel Due to Latisse?

One very rare risk is an increase in brown pigmentation, however I haven't heard about brown eyes turning lighter.  This should be checked out by your opthamologist.

Hi there-

While color change with Latisse use is possible, it is only possible in patients with GREEN eyes....

When Latisse changes the color of the iris, what is going on is that the already dark (pigmented) areas are getting darker...

This is why people with blue eyes are at no risk (they have no pigmented cells to get darker), and why people with brown eyes are at minimal risk (their eyes are already maximally pigmented).

People with green eyes have some pigment, and with repeated misuse of the product (it really would require you to misapply it regularly), their eyes might darken...

Your situation does not sound like what you might ascribe to Latisse.

Lumigan have been known to create brownish tint to hazel eyes and green eyes, but I've not heard of a lightening effect to the iris "halo".

Most of my patients have used Lumigan instilled in the eye for years with no change in color. Some though, do find they have iris darkening. This is product instilled IN the eye, and not on the lash line as Latisse is applied.

I would not think Latisse is the cause. It might be a good idea to bring this up at your next eye exam. An ophthalmologist could rule out any other condition that you might be experiencing that is unrelated to Latisse but just happens to be occurring at the same time.
