Bimatoprost is a prostaglandin drug. It was first used to treat eye diseases such as glaucoma. The drug name is lumigan. However, during the treatment, the patient unexpectedly found that the diameter, length and density of his eyelashes had increased significantly. After that, bimatoprost was used in the clinical trial of eyelash beauty. Its great effect on eyelash thickening and densification directly led to the targeted launch of lattise by Erjian, lumegan's production company. The drug was approved by FDA in December 2008 and became a professional product for blackening and thickening eyelashes.
