Caffeine is a highly effective skincare active known for its ability to reduce puffiness, brighten dark circles, and energize tired skin. It works by constricting blood vessels and stimulating microcirculation, which helps minimize under-eye swelling and discoloration.

In addition to its de-puffing action, caffeine provides antioxidant protection, helping to neutralize free radicals and environmental stressors that contribute to premature ageing. With regular use, the under-eye area appears smoother, more awake, and refreshed, with reduced signs of fatigue and shadowing.
