Ferulic Acid sits in our formulas for one job: defending skin against everyday environmental stress. We file it under Antioxidant Defence in this glossary because that is the effect its evidence actually supports, not because it is the most flattering label available.

Constancy in the pairing

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.

Constancy in the evidence

Our source is a randomised controlled trial published in an indexed journal, recorded as Lin 2005 PMID 16185284. You can read it yourself at PubMed 16185284. We grade that as the strongest kind of evidence we recognise.

Constancy and its limits

The research behind Ferulic Acid studies the ingredient, not the finished Opuliss product it sits in. It supports what Ferulic Acid 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.
