Puffy eyes show up for all kinds of reasons—late nights, salty food, allergies, or just how your body holds onto fluid. The skin under your eyes is thin, so even small changes like excess tears, blocked blood vessels, or mild irritation can cause swelling. You might notice bags under the eyes, dark circles, or puffy eyelids that won’t budge. Allergy symptoms, thyroid disease, dry eye, or even your eye makeup and contact lens solution can make things worse. For some, it’s just how their lower lids are shaped or how fat is stored in the area. Before turning to treatments like eyelid surgery or laser resurfacing, it helps to try simple puffy eyes remedies first. A cold compress, less salt, caffeine-based eye creams, or cucumber slices can all help reduce puffiness and calm the under eye area. Keep going for dermatologist-approved ways to reduce puffy eyes and improve how your skin looks and feels.
