What does Caffeine do?#

Caffeine is a naturally occurring plant compound and one of the most widely used ingredients in eye area products. It is formulated into eye creams and serums to support a brighter, more refreshed-looking under-eye area.

  • Supports a brighter-looking under-eye appearance
  • Contributes to a more refreshed, awake-looking eye area
  • Provides antioxidant support against everyday environmental stress

How it works

Caffeine is a naturally occurring antioxidant. Around the eye area it is used to help the skin look brighter and more refreshed, and its antioxidant properties support an eye area that looks healthy against everyday environmental stress.

How to use Caffeine#

  • Morning or evening — the evidence supports either, so use whichever fits your routine.
  • Around the eye area only, on the orbital bone: the ridge you can feel under the eye and along the brow.
  • Not on the eyelid and not along the lash line. Product placed inside the orbital rim tends to migrate into the eye as you blink.
  • Pat it in with a fingertip. Do not rub or drag — the skin here is the thinnest on the body, and rubbing your eyes works against the very look you are treating.
  • Every day from the start is fine. Caffeine is gentle and has no easing-in period.
  • If it gets into your eye, rinse with water.
  • It sits comfortably alongside the rest of a routine, so it does not need an evening of its own.

For external use around the eye area only. Avoid direct contact with eyes; if product gets into the eye, rinse with water. Discontinue use if irritation occurs.

How we check this#

Everything on this page traces to the sources listed below — regulators' own publications and published studies. Where the evidence does not answer a question, it is left unanswered.

Some sources below are the official product information for prescription medicines — some contain this ingredient at higher strengths, others are cited for how they interact with it. We use them for their safety and handling detail only. A cosmetic product is not one of those medicines and is not intended to treat any condition.
