What is Caffeine?
Caffeine (INCI: Caffeine) is a purine alkaloid naturally found in coffee, tea and guarana. In topical skincare it is best known for its vasoconstrictive and antioxidant properties, making it a staple of de-puffing eye creams and anti-fatigue formulas.
How It Works
Caffeine reduces visible under-eye puffiness by constricting superficial blood vessels, which lowers fluid retention in the periorbital area. It also scavenges free radicals generated by UV and pollution, and supports firmer-looking skin when combined with depuffing peptides.
Market Context for Brand Owners
Caffeine eye cream is a consistently high-demand Amazon US keyword at roughly 50,000 monthly searches, sustained year-round as a daily eye-care staple. Demand is led by de-puffing and dark-circle claims, making it a strong private-label entry point for eye care OEM.
Formulation & Manufacturing Notes
Caffeine is water-soluble, stable at pH 4.0-7.0, and compatible with niacinamide, peptides, vitamin C and hyaluronic acid. Typical eye-cream levels are 1-5%, often paired with matrixyl or EGCG for anti-fatigue synergy. Avoid high heat during manufacturing.
Regulatory Status
Caffeine is permitted in cosmetics in the US, EU, Korea and most export markets. At typical cosmetic levels (1-5%) it is not a regulated drug ingredient; eye-area products should still follow local claim guidelines.
