## Why It Works
Under-eye puffiness is caused by fluid retention in the loose connective tissue beneath the lower lid. As egg white dries, the protein film it forms contracts and applies gentle mechanical compression to the surface of the skin, which temporarily reduces the visible puffiness in the same way a cooling eye compress does — by physical pressure rather than biochemical change. The effect is cosmetic and temporary, lasting a couple of hours.
## How to Do It
1. Wash your hands thoroughly.
2. Separate one egg. You only need a very small amount of white.
3. Dip a clean fingertip into the white. You want a thin coating, not a glob.
4. Apply gently under the eye from the inner corner to the outer, along the orbital bone. Stay below the lash line — do not apply to the eyelid.
5. Keep your eyes closed or look upward while the white dries — about 5 minutes.
6. Rinse carefully with cool water.
7. Follow with your regular under-eye serum or moisturizer.
## Pro Tips
- Keep your eyes closed while it dries. Egg white near the eye rim can sting if it migrates onto the eyeball.
- Cold egg white applied straight from the fridge works better — the cold also reduces puffiness through vasoconstriction.
- This is a temporary fix, not a treatment. If you have chronic under-eye puffiness, address the underlying cause: sleep, salt intake, allergies.
