Dark circles and puffy eyes: what helps and what does not

The skin under your eyes is thinner than the skin on the rest of your face. Small changes in sleep, salt, allergies or sun show there first. Most dark circles and puffiness are cosmetic, and some simple habits can soften them.

Why the under-eye area looks dark

1. Shadows. With age, the skin and fat under the eyes change shape. This can make a hollow that catches shadow.
2. Pigment. Some people, especially people with deeper skin tones, have more pigment in this area. Sun exposure can make it darker.
3. Visible blood vessels. Thin skin lets blood vessels show through, which can look blue or purple.
4. Rubbing. Allergies and itchy eyes make people rub, and rubbing can darken the skin over time.

Why eyes look puffy

Fluid collects easily under the eyes. You may notice it more in the morning, after a salty meal, after crying, or during allergy season. Puffiness that comes and goes during the day is usually fluid.

Habits that help

1. Sleep on your back with your head a little raised. This helps stop fluid from collecting overnight.
2. Use something cool. A cold, damp cloth or chilled eye patches for a few minutes can make puffiness look less.
3. Wear sunscreen and sunglasses. Sun exposure can darken pigment around the eyes. Apply sunscreen close to the eye area, but not on the lids.
4. Do not rub your eyes. If allergies make them itch, talk to a pharmacist or doctor about the allergy itself.
5. Remove eye makeup gently. Hold a soaked cotton pad on the eye for a few seconds, then wipe. Do not scrub.

What eye products can do

Eye creams cannot change the shape under your eyes or remove a hollow. They can still help the area look better:

1. Caffeine can make morning puffiness look less for a short time.
2. Hyaluronic acid and ceramides hydrate the skin, so fine lines look softer.
3. Gentle brightening ingredients, such as niacinamide or vitamin C, can help pigment look more even over several weeks.

Use a small amount and pat it on with your ring finger. Keep it below the eye and on the bone, not on the lid.

When to see a doctor

See a doctor if the swelling is painful, appears on only one side, comes with itching or a rash, or does not go away. Sudden changes are worth checking.
