Upneeq is the only FDA-approved prescription eye drop for acquired ptosis (low-lying lids) that lifts your upper eyelids to open your eyes. The drops work by activating receptors in the upper eyelid muscle. When the muscle contracts, the upper eyelids can lift about 2mm, giving a more open, alert look for hours. Results can be seen in as little as 5-15 minutes and last up to 8 hours. Upneeq significantly improves upper field vision, resolves tired-looking or asymmetrical eyes and is a non-surgical alternative to blepharoplasty.
