Allergan also notes that Latisse may cause darkening of the eyelid skin, which may be reversible, and it "may also cause increased brown pigmentation of the colored part of the eye, which is likely to be permanent."
Latisse may also promote hair growth in other skin areas that it frequently touches, so Allergan recommends blotting it off any skin other than the upper eyelid's lash line to prevent that side effect.
According to Allergan, Latisse was well-tolerated in its clinical trials, with the most common side effects being eye redness, itchy eyes, and skin hyperpigmentation.quelle webmed.com
