Plum 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.

Calm in the orchard

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.

Calm in the evidence

Our source is a safety assessment or regulatory listing, recorded as Navarro 2018 PMID 29385709. You can read it yourself at PubMed 29385709. We grade that as a safety and status source rather than an efficacy one.

Calm and its limits

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