Caffeine
Antioxidant & de-puffing
Caffeine is an antioxidant that passes through the skin easily. In skincare it is mostly used in eye products for puffiness and dark circles, and in body products for the look of cellulite. The effects are real but modest and temporary.
What is Caffeine?
An antioxidant that temporarily tightens and de-puffs skin by constricting blood vessels. Often found in eye products to reduce the look of puffiness and dark circles.
In skincare terms, Caffeine is an antioxidant that helps defend the skin against environmental stress.
What caffeine does
Caffeine has antioxidant properties, may help protect skin cells against UV damage, and increases blood flow in the skin. It also speeds up the breakdown of fat in fat cells, which is why it is used in anti-cellulite products. Topical products typically contain around 3% (Herman 2013).
Caffeine for puffy eyes and dark circles
Eye creams use caffeine to reduce morning puffiness and the look of dark circles. There's little independent clinical evidence for these claims, and part of the effect of a cool gel or metal applicator is the cold itself. Dark circles caused by pigmentation or by the shape of the face won't change much with any cream.
How to use it
- Pat a small amount of eye product around the orbital bone in the morning.
- Keeping it in the fridge can add to the de-puffing effect.
- Sleep, salt and alcohol intake and allergies often affect puffiness more than any product.
Side effects
Caffeine is generally well tolerated on skin. Irritation from eye creams is more often caused by fragrance or preservatives than by caffeine.

Does caffeine eye cream really work?
It can make puffiness look a little better for a few hours. It won't remove dark circles caused by pigmentation or hollows.
Does caffeine in skincare keep you awake?
No. The amount absorbed from skincare is far too small to have that effect.
Can caffeine help cellulite?
It is a common ingredient in cellulite creams, but any visible change is small and temporary.
