Caffeine

Caffeine is a naturally energising ingredient commonly found in eye creams, serums and body products. It is prized in skincare for its ability to temporarily tighten and brighten the appearance of skin, especially around the eyes. Shoppers often look for it in formulas targeting puffiness and dullness.

How it works in skincare

In cosmetics and skincare, caffeine works as a vasoconstrictor that can help reduce the look of under-eye puffiness by temporarily constricting blood vessels. It also offers antioxidant properties that protect against free-radical damage while providing a mild stimulating effect on the skin, improving the appearance of firmness and tone. You will frequently find it paired with hyaluronic acid or peptides in eye gels and cellulite creams for its complementary draining and toning effects.
