Caffeine 1%

Summary

A methylxanthine that supports microcirculation in the delicate skin around the eye, visibly de-puffing and refreshing the look of a tired, heavy morning face.

Awakening in the formula

Caffeine 1% sits in our formulas for one job: easing the look of puffiness. We file it under De-Puffing in this glossary because that is the effect its evidence actually supports, not because it is the most flattering label available.

Awakening in the eye contour

The mechanism is the one stated in the summary above, and we have deliberately not extended it. Where a supplier or a competitor would reach for a bigger promise, the sentence we publish stops where the research stops.

Awakening in the evidence

Our source is a peer reviewed observational or laboratory study, recorded as Herman 2013 PMID 23075568 (review). You can read it yourself at PubMed 23075568. We grade that as solid support for what the ingredient does.

Awakening and its limits

The research behind Caffeine 1% studies the ingredient, not the finished Opuliss product it sits in. It supports what Caffeine 1% does. It is not a trial of our formula, and we will not present it as one.

Cosmetic claims describe how skin looks and feels. Nothing here is a medical claim, and nothing here treats a condition.
