Careprost Eyelash Serum is a brand name for a medication that contains bimatoprost as its active ingredient. Bimatoprost is a prostaglandin analog that is commonly used to treat certain eye conditions. Careprost eye drops are often used for cosmetic purposes to enhance the growth of eyelashes. Like Lumigan, which also contains bimatoprost, Careprost can be prescribed for the treatment of glaucoma and ocular hypertension. It helps to lower intraocular pressure (IOP) by increasing the outflow of aqueous humor from the eye, reducing the risk of optic nerve damage and vision loss.
