What's actually doing the work
Caffeine
1,3,7-Trimethylxanthine / Eye Area Vasoconstrictor
Antioxidant
Topical caffeine works as a potent vasoconstrictor (reducing undereye puffiness and dark circles), a phosphodiesterase inhibitor (breaking down fat in adipocytes for cellulite applications), and an antioxidant protecting against UV-induced DNA damage. Studies show significant improvement in undereye puffiness and dark circles at 3%.
Green Tea Extract
EGCG / Epigallocatechin Gallate / Camellia Sinensis
Botanical
Rich in catechins, primarily EGCG — a potent free-radical scavenger, anti-inflammatory, and mild androgen receptor inhibitor relevant to sebum reduction. Topical EGCG reduces sebum, calms inflammatory acne, provides UV photoprotection, and inhibits MMP activity that degrades the dermal matrix.
