Careprost is a serum that is used to grow eyelashes and eyebrows. The active ingredient, Bimatoprost Ophthalmic, does this by making the eyelashes more dense, thick, and long. Bimatoprost Ophthalmic also increases the amount of fluid in the eye, and it can be used to treat glaucoma, too. Its eyelash growth serum effect was later found out about, and the active ingredient was used by Latisse. Buy Careprost online in the United States and Canada for a fraction of the price of Latisse.
