With its FDA approval, Upneeq is widely recognized for its efficacy in treating drooping eyelids. A small percentage, around 1% of users, might notice side effects like inflammation, redness, or blurred vision post-application. However, these unwanted effects diminish over a few hours. It's vital to discuss any existing medications or eye-related history with Dr. Schwarzburg to ensure a seamless and safe Upneeq experience.
