Glaucoma and other eye conditions are treated with careprost eye drops. Bimatoprost is the active medicinal ingredient in Careprost. Careprost is available online at Skinorac. It can be purchased as an eye serum. The effects of Careprost take a minimum of three to four weeks to manifest. By causing more aqueous fluid to exit the eyes, it lowers intraocular pressure. Because it encourages the creation of new lash hair, Careprost also functions as an eyelash serum. To avoid drug dilution when taking multiple medications, wait 5 to 10 minutes between eye prescription refills.
