In order to ensure you are receiving authentic, FDA-approved Latisse distributed by its company, Allergan, you need to receive it from a Board Certified Dermatologist or Plastic Surgeon's office. In some states, such as Texas, physicians are unable to distribute presciption medications unless a pharmacist is on staff at their office. In these cases, a patient will receive a precription for Latisse to be taken to a reputable pharmacy for the Latisse to be filled.
Latisse is a medication that is distributed by Allergan. Since it is a medication it can only be dispensed by a physician or as a written prescription through a pharmacy. In the United States if you are purchasing through a reputable physicians office or pharmacy you should not have any problems. It is when you try to purchasing online or from out of the country when you start to encounter "knock offs." Another indication as to whether it is legitimate is whether the lot number allows you points in the Allergan Brilliant Distinction program. You can always call the pharmaceutical company to confirm if the product is authentic when in doubt.
