Can my 15 Year Old Daughter Use Latisse?

According to Allergan, latisse use in pediatric patients below the age of 16 years is not
recommended because of potential safety concerns related to
increased pigmentation following long-term chronic use. Proceed with caution.

Latisse is approved by the FDA for patients ages 18 years and older. Since your daughter is 15, technically she is not able to receive the treatment. I would suggest waiting until the recommended age to undergo Latisse. 

The percentage of changing blue eye color is so minimal, be sure to apply a thin layer to the lash line like liquid eyeliner before going to bed at night.  Latisse does require a prescription.  It can also darken the skin a little along the lash lids but make up covers this up well.  Check with your dotor if he prescribes Latisse to patients under 18 years old.

Although there are no studies showing the safety of Latisse in teenagers, it should be perfectly safe as long as it is properly used. Parental guidance is advised!

Frankly, we don't do studies on people less than 18 years of age for cosmetic procedures. I would see no reason why this wouldn't be safe, assuming you oversee how she uses it. Young people have a tendency to overdo things and think that if a little is good, a lot is better. So as long as your daughter uses the medication as directed - once per day only - and puts it on correctly - across the top lash line only - there should be no problems with her using it and not having any issues with her blue eyes.
