Lumigan was originally produced to treat glaucoma, but after patients noticed it also grew their lashes, drug maker Allergan got the Food and Drug Administration to approve the drug for lash treatments.
"We finally have a cosmetic drug that will give us the benefits that we wanted to have: longer lashes, darker lashes, thicker lashes," Dr. Fiona Wright said. "But we also have the safety to back it."
Chrissie Taveira got a prescription for Latisse from her doctor for her "really stubby" and blonde eyelashes.
Doctors say most people see results in one to two months if Latisse is applied nightly.
The drug is applied to the top of your upper eyelid like an eyeliner.
Christine Newell said her eyelashes are longer and healthier after using Latisse.
Latisse is the only eyelash enhancer on the market that is FDA-approved.
The drug can last up to two months and costs $119.
To buy it, patients must be at least 18 years old and have a doctor's prescription.
