Caffeine
Caffeine is a vasoconstrictor that temporarily reduces puffiness by narrowing surface blood vessels, and an antioxidant that offers modest protection against UV-induced damage. It's ubiquitous in eye creams marketed for dark circles and morning puffiness.

Evidence level
Promising for topical use. Effective for temporary depuffing and antioxidant protection. Dark circle improvement is more conditional — most effective on vascular (blue-toned) dark circles, less effective on pigmentation-based ones.
