I've used Latisse for more than 3 years. I have 3 light-eyed friends that have used it longer than I have. None of us have ever experienced an adverse effect as a result of using this product. It does NOT change your eye color or cause you to have "sunken eyes." I'm posting a few pictures that I've taken over the past year.
If you're interested in the product, TRY it! I love the results and I'm so glad I tried it for myself!!!
