Morning puffiness around the eyes is rarely mysterious — it is usually last night's sodium, a few extra hours face-down on a pillow, or both. The skin there is thinner than almost anywhere else on the face, which means it shows fluid retention fast and also means it needs a lighter hand than the rest of a routine.

Cold is the first lever worth pulling. Chilled eye patches, kept in the fridge overnight, do more work in the first few minutes after cleansing than anything applied at room temperature. From there, less is more: a small amount of a lightweight eye cream or serum, pressed rather than rubbed in, since the goal is hydration without adding more puffiness through friction.

The last step is where people tend to overdo it. A cool metal-tipped applicator or roller, used with light pressure, gliding from the inner corner outward toward the temple, helps move fluid along rather than just masking it. Pressing hard or dragging the skin back and forth does the opposite of what you want in an area this thin — the motion should feel more like a light sweep than a massage.

None of this replaces sleep or a lower-sodium dinner, but as a five-minute step before makeup, it is enough to take down the swelling that would otherwise show up in every photo taken before 10 a.m.
