What Caffeine does

Helps the look of tired, puffy eyes
Gives a light, refreshing feel
Supports scalp-care formulas

Caffeine occurs naturally in coffee beans, tea leaves, and cacao. Most cosmetic caffeine is either extracted from plants or made in a lab, which gives formulators a consistent, pure supply. It is a white, slightly bitter powder that dissolves well in water-based formulas.

Formulators use caffeine for its stimulating character and its place in eye and scalp care. Its effect on the look of skin is usually modest and short-lived, so it works best as one part of a routine. You will often see it in cleansers, eye creams, and self-tanning products too.

Good for

Anyone wanting an eye cream or scalp product with a lively, refreshing feel. Most skin types tolerate it well.

Frequently asked questions

Does caffeine help with puffy eyes?

Caffeine is often used in eye creams to help the look of puffiness. Its effect is usually mild and short-lived, so it is best seen as a gentle, cosmetic boost. Good sleep, cool compresses, and a steady routine can also help.

Is caffeine safe for sensitive skin?

Caffeine is generally well tolerated, and it is not commonly linked to irritation. Sensitive skin can still react to any ingredient, though. Patch test a new product on a small area first, and stop using it if redness or itching appears.
