Can Latisse Change my Light/dark Blue Eyes Brown? (photo)

This is probably the most asked question for patients before starting Latisse. Similar to what the other physicians have previously stated, there is no guarantee it will not happen. However, this is much more likely should the product be placed in the eye and not superficially on the lash line. It is very important not to put the product directly in the eye. In following these directions, the risk is lessened. I have personal experience in prescribing the product to multiple light eyed individuals with no change in iris pigmentation. That being said, there is always potential for this side effects to occur.  

It is a very rare risk but you may experience an increase in brown pigmentation in your irises. However, I haven't noticed this in any of my patients to date, and in fact, a staff member who works at my practice hasn't had this happen to her even though she has green eyes. If you see this happening to you, you should stop using Latisse, however, there is a risk that the change may be permanent.  

Latisse, when used properly and applied to the lash line NOT the eyeball (as it's parent drug Lumigan--an ophthalmologic glaucoma drug--was used), will not change your blue eyes brown (even with the small dot of brown you have mentioned).

But if you want guarantees, no reasonable physician would prescribe this to you, nor should you use it. The trouble is that every thing we do in life has some degree of uncertainty, including stepping off a curb into traffic, driving your car to work, or running into your home during a rainstorm! So you have to do your due diligence, perhaps even some Google research, and ask experts their opinion.

BTW, my dad always used to say X is an unknown quantity, and spurt is a drip under pressure, so don't call [me] an "expert."

So even though all of us here have prescribed this drug for hundreds if not thousands of users without blue eyes turning brown, you have to decide for yourself what you want to do. Asking different ways additional times will truly not change the answer. I hope that was gentle. Kindest best wishes! Dr. Tholen

It is usually hazel or green eyes that have the most propensity for darkening. Light eyes have so little pigmentation, that the bimatoprost [Latisse] cannot really do much to increase the pigmentation.

Furthermore, the amount of the drug that is applied to the lashes is much lower than the eye drop application for glaucoma, which has a higher likelihood of changing eye color.

Thank you for your question.

This is the most common question I hear and from the studies, I don't believe that they show anyone who has had iris color changes with applying Latisse to their lashes-- if this side effect occurs, it is very rare. 

They saw these changes when the glaucoma medication was put directly into the eye.

Theoretically, your blue eyes should not turn brown from the use of Latisse.  I have not seen any irides change color during my years of dispensing Latisse.  In studies, soms hazel and green colored irides became more pigmented with the use of Latisse or other prostaglandin solutions (used to treat glaucoma). However, the spokeswomen for the product, Brooke Shields and Claire Danes have hazel and green eyes and have not experienced any change in color.  If you are concerned, by all means discontinue use.  There are other ways to achieve  fuller darker and longer lashes.

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. So there it is - the same answer over again!

Ok, so you know the answers, but here it is again. Latisse can only darken the eyes if they already have pigment present. So, it doesn't change blue eyes to brown. But it could theoretically make hazel or green eyes with flecks of brown in them, more brown. I have not seen this happen with anyone, after several thousand kits being sold in my office, but that's the answer. It can only darken the pigment that's already there. If you have no brown pigment in your blue eyes, it can't make your blue eyes turn brown.
