Maybe you have heard of Latisse, which is an FDA approved serum to increase eyelash size, its main ingredients is bimatoprost. So, the next question is what is bimatoprost, how does it work to enhance eyelash?
According to Wikipedia, Bimatoprost is a prostaglandin analog used topically (as eye drops) to control the progression of glaucoma and in the management of ocular hypertension. It reduces intraocular pressure (IOP) by increasing the outflow of aqueous fluid from the eyes. In December 2008, the indication to lengthen eyelashes was approved by the U.S. Food and Drug Administration (FDA); the cosmetic formulation of bimatoprost is sold as Latisse.
Generally speaking, almost all of the serums in the market claiming to regrow eyelash that contains bimatoprost or other kind of prostaglandin analog. This substance has proven to be the effective ingredient to lengthen your eyelash.
If you want to apply bimatoprost serum, just take a try of Latisse, being the only and first FDA approves serum, its effect is obvious to all. But if you are hesitate of Latisse's high price, you can take a try of cheap version of Latisse, such as Carerprost, which has same ingredients as Latisse, and the price is only one third of latisse.
