What is caffeine?
Caffeine is a natural compound found in coffee beans, tea leaves and cacao. In skincare it is used in a purified form, a fine white crystalline powder that dissolves easily into water-based formulas like eye creams and gels.
What caffeine does for skin
Applied to skin, caffeine helps reduce the look of puffiness and helps the under-eye area look brighter and more awake. It also has antioxidant properties that help defend skin against everyday environmental stress.
How it works
Caffeine is known for its tightening effect on the look of the skin around the eyes. It is thought to help by encouraging tiny blood vessels near the surface to narrow and by supporting the movement of fluid that can collect under the eyes overnight. The result is a smoother, less puffy, more rested look.
Caffeine is a small molecule that can pass into the outer layers of skin, which is one reason it is so widely used in eye care.
Why MEG 21 uses it
Bright & Firm Eye Treatment pairs caffeine’s quick, refreshing effect with ingredients that work over time: peptides and bakuchiol for a smoother, firmer look, niacinamide, licorice root and a vitamin C derivative for brightness, and Supplamine® for anti-glycation, helping protect collagen in the thin skin around the eyes.
How to use it in your routine
Use a rice-grain amount of Bright & Firm Eye Treatment for both eyes. Tap it gently along the orbital bone with your ring finger, moving outward, rather than rubbing. Keeping it in a cool place makes the morning application feel even more refreshing. Follow with sunscreen in the morning.
Who is it for?
Caffeine suits anyone with morning puffiness, tired-looking eyes or dark-looking circles. It is gentle and works well for most skin types, including sensitive skin around the eyes.
