An antioxidant stimulant used in scalp care to invigorate the follicle environment, and to de-puff on skin.
What it is
Caffeine is a well-known stimulant and antioxidant. In scalp and hair care it is used to create an invigorated, stimulated scalp environment and is a popular ingredient in products aimed at supporting fuller-looking hair. On skin, its constricting action makes it a common choice for de-puffing, particularly around the eyes.
How it works
Invigorates the scalp
It stimulates and refreshes the scalp environment, a supportive base associated with healthy-looking hair.
Antioxidant and de-puffing
It offers antioxidant protection and, via mild vasoconstriction, can reduce the look of puffiness on skin.
The evidence
Caffeine has good support as an antioxidant and scalp-stimulating ingredient, and is widely used in scalp and eye-area products.
Worth knowing
A supportive scalp-vitality ingredient. It energises the scalp environment as part of a wider hair-care approach.
