The first drug that can enhance eyelash growth has got an approval by the FDA. The drug called Latisse will be manufactured and marketed by Allergan.

Basically the drug would be used as a prescription for those people who do not have enough growth of the eyelashes.  Surprisingly the chemical bimatrophost, which is also used in glaucoma treatment, would be the chief ingredient of the drug.

The drug is a structural prostaglandin analog, a lipid compound derived from fatty acids. It helps in binding prostaglandin receptors. Prostaglandin receptors are present in hair. They help in development and re growth of the hair follicle.

Anyone opting for the treatment can expect longer, darker and fuller lashes within 8 - 16 weeks. But once the treatment is stopped, the lashes would come back to their original structure.

The company has also issued warning as Latisse could lead to darkening of the eyelid skin or brown pigmentation of the colored part of the eye. But it would be reverse on the cessation of the treatment.  It can also cause red and itchy eyes.

It is expected that  the drug would  generate sales of $20 million in 2009, growing to $80 million in 2012.
