Apparently, your favorite eyelash serums that gives you falsie-like length could potentially change the color of your eyes.

Yes, even some of the OTC options.

Eyelash serums are popular, and it’s not hard to see why.

Muneeb Shah, D.O., a dermatology resident physician, pointed out as much in a recent Instagram post.

“Especially the ones that contain prostaglandins or prostaglandin analogues.”

But that’s when he dropped the mind-blowing side effect.

“Unfortunately, they can also cause hyperpigmentation around the eye.

But not just that they may actually darken your eyecolor.”

Latisse, the only prescription eyelash serum, contains bimatoprost, a prostaglandin analogue, withresearch-backedlash-growing potential.
