What Are the Side Effects of Latisse on Eyebrows?

Latisse is only FDA approved for the eyelashes, however there are reports that it can achieve an improvement for brows as well. The side effects may include darkening of the brows and the skin in the area. Please talk to the doctor who prescribes your Latisse before using it on the eyebrows.

My understanding is that Latisse works very well on thin eyebrows due to the same mechanism that it works on eyelashes. The company will not say whether they are involved in studies for this indication, and this use is considered off label. Some patients after application to the eyelid, use the same applicator and brush some Latisse on their eyebrows. There is a chance of darkening pigment of the skin of the eyebrow area, but this shoud be reversible and if carefully applied may be cosmetically enhancing.
Officially, I cannot recommend this use since it is off label, but you should discuss it with your doctor before proceeding.

Latisse causes the growth of longer, thicker, and darker lashes.  It is approved by the  FDA for use on the upper eyelashes. Theoretically, it could be used on the eyebrows, but it is an "off-label" use.  I have heard of some patients using it with some success. However, the prescription is generally written for use on the upper eyelahes.  I hope this helps.
