Prescription topical. Bimatoprost 0.03% is applied once daily as a thin line to the skin of the UPPER eyelid margin at the lash base (not to the lower lid, and avoid getting it in the eye), using a fresh applicator per eye. Continuous use is needed to maintain results. Use under a clinician, especially if you have glaucoma or take prostaglandin eye drops. There is no oral or systemic use. This library does not provide an ingestion protocol.
