Alpha-Arbutin
Summary
Helps fade the look of dark spots and even tone by gently targeting pigment.
Light in the formula
Alpha-Arbutin sits in our formulas for one job: evening the look of tone. We file it under Brightening in this glossary because that is the effect its evidence actually supports, not because it is the most flattering label available.
Light in the melanocyte
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.
Light in the evidence
Our source is a randomised controlled trial published in an indexed journal, recorded as Boissy 2005 PMID 16026582. You can read it yourself at PubMed 16026582. We grade that as the strongest kind of evidence we recognise.
Light and its limits
The research behind Alpha-Arbutin studies the ingredient, not the finished Opuliss product it sits in. It supports what Alpha-Arbutin 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.
