Public databaseCAFFEINE
Caffeine is the same molecule as in coffee. In skin products it is used as an antioxidant and for its vasoconstricting effect; for under-eye puffiness the evidence is modest. The strongest evidence comes from a 2015 human trial: In a single-blind trial of 11 women, an eye pad containing 3% caffeine and 1% vitamin K in an emu-oil base was worn under one eye and a water pad under the other for four weeks. Visual and instrument assessment found less wrinkle depth and lighter dark circles on the caffeine side. 2015 · 11 people · healthy women · PMID 25625116 · This pad also contained 1% vitamin K and an emu-oil base. 11 women took part, the trial was single-blind, the control was a water pad. Wrinkle reduction was the main aim; dark circles were assessed alongside it. 3 products contain Caffeine; the highest it appears is number 19 of 43.
