Maru Derm Caffeine 5% Eye Contour Serum revitalizes tired eyes with its specialized 30ml formula. Caffeine constricts blood vessels to reduce puffiness and dark circles while improving microcirculation for a brighter, more awake appearance. This lightweight serum penetrates the delicate eye area without irritation, delivering visible lifting and firming benefits that minimize fine lines and crow's feet. The potent concentration works efficiently to restore luminosity and resilience to tired, aged eyes. Apply morning and night for noticeably refreshed, youthful-looking eyes that appear well-rested and radiant.
