Caffeine

Caffeine is a naturally occurring alkaloid widely used in skincare for its potent antioxidant, anti-inflammatory, and vasoconstrictive properties. When applied topically, caffeine helps protect skin from oxidative stress by neutralizing free radicals, supporting collagen and elastin integrity, and delaying visible signs of aging such as fine lines and sagging. Its ability to constrict blood vessels and enhance microcirculation reduces puffiness, dark circles, and redness—making it especially effective in eye creams and products targeting tired or swollen skin. Caffeine also soothes irritation, calms inflammation, and delivers a firmer, more radiant complexion, while its non-comedogenic, water-soluble profile ensures compatibility with all skin types in serums, creams, and masks.
