Caffeine (topical)

Also known as Coffee extract, caffeine in skincare

CEVIDENCE

Coffee for the outside. Tightens the look, wakes the surface.

The honest take

The tightening is real and temporary — closer to a good camera angle than a transformation. As an antioxidant-plus-exfoliant it's a genuinely nice thing to do to body skin; as a 'cellulite cure' it's marketing, and we're not selling the second thing.

What it is

The same molecule you drink, used on skin in scrubs and creams for its temporary tightening and antioxidant properties.

How it works

Topically, caffeine is an antioxidant and mild vasoconstrictor, which gives that briefly firmer, de-puffed look; in a scrub, the grounds add physical exfoliation.

What it does

Helps skin look temporarily tighter and more awake, and — in a scrub — buffs the surface smooth so it takes moisture and light evenly.

Who it's for

Anyone who wants smoother-looking, briefly-tightened body skin before less clothing is involved.

How to use it

Massage a coffee scrub into damp skin in firm circles two or three times a week, then rinse well. Always the night before any plan that shows skin.

What to expect

Immediately smoother, temporarily tighter-looking skin; the effect is real and short-lived.

The research

Topical caffeine has antioxidant and vasoconstrictive activity in studies; the firming look is temporary, and claims about fat or cellulite are not supported.

Read the labelExternal use only; mind the eyes and broken skin. Not a treatment for cellulite, fat or any condition — the tightening is temporary. Oily scrubs make the shower floor slick.

Evidence grades describe how well an ingredient is studied — A well-supported, C emerging — not a promise of results. Educational, not medical advice. Doses are typical ranges; follow the label on the product.
