Inkey List Guide
Dark circles and puffiness can be caused by a number of factors. If you are genetically predispositioned to dark circles, caused by pigmentation underneath the eye, or puffiness under the eye caused by fat deposits, unfortunately caffeine serum is unlikely to help.
Caffeine is however, a fantastic way to reduce puffiness and dark circles caused by a number of lifestyle factors such as lack of sleep, travelling, diet and high salt intake amongst others. Applying caffeine topically essentially helps to stimulate circulation in the under-eye area, which can help with the appearance of dark circles. It also has diuretic properties, so can aid with water retention which is a common cause of under eye puffiness.
As an antioxidant, it also has preventative properties, and can protect the eye area from free radicals and environmental stress. Ensuring you are always wearing sunscreen will also help.
For an extra soothing effect, a tip would be to keep your caffeine in the refrigerator and massage gently into the under-eye area to stimulate circulation.
