The product targets both dark circles and puffiness, giving one small bottle a fairly specific job description. Choose it for an appearance concern, rather than treating the word "solution" as a promise to solve every kind of eye bag.1

What can caffeine actually do?

Caffeine can narrow blood vessels, a property called vasoconstriction. In eye skincare, caffeine can help improve the appearance of puffiness and dark circles. Think of the serum as a cosmetic option for making puffiness less noticeable, not a way to permanently remove eye bags.123

Which kind of puffiness are you dealing with?

Fluid can build up in the thin tissue around the eyes and eyelids, creating a puffy appearance. Salt, poor sleep and allergies can contribute. Bags that keep returning can also reflect inherited fat pad prominence, bone structure or loose skin; these can be difficult to fully correct without medical treatment.2

What else helps ordinary puffiness?

For a cool compress:

  1. 1Soak a clean washcloth in cold water.
  2. 2Lie down and place the washcloth across your eyes for a few minutes.
  3. 3If you use an ice pack instead, wrap it in a towel to protect your skin.

Cold helps restrict blood vessels and reduce swelling. If puffiness follows salty meals or poor sleep, limiting salty foods and aiming for seven to nine hours of sleep can help. Raising your head slightly with another pillow can reduce fluid buildup overnight.2

What if an eye product makes swelling worse?

Eye creams and makeup can irritate the eyes or surrounding skin. If you suspect a product is contributing, stop using it for at least a couple of weeks to see whether symptoms improve. Remove contact lenses immediately if your eyes or eyelids swell.2

When should you get your eyes checked?

Have eye swelling that lasts longer than 24 to 48 hours checked by an eye care professional. An itchy, flaky, sticky or swollen eyelid can have causes such as allergy, eyelid inflammation or conjunctivitis; do not assume it is simply cosmetic puffiness.24

Seek urgent medical assessment if:

  • Your swollen eyelid is red, hot, painful, tender or blistered.
  • You have pain inside the eye, marked redness or sensitivity to light.
  • Your vision changes, your eyelid suddenly droops, or you cannot open your eye.
  • Eye symptoms come with a headache, nausea, vomiting, a high temperature or feeling generally unwell.
  • You think the swelling is an allergic reaction.
