All Ingredients/Zinc PCA
Zinc PCA
Summary
A zinc amino-acid salt that helps with the look of oily skin and mattifies the appearance. Supports the look of a balanced, blemish-prone complexion.
Freshness in the formula
Zinc PCA sits in our formulas for one job: keeping pores clear and shine in check. We file it under Clarifying in this glossary because that is the effect its evidence actually supports, not because it is the most flattering label available.
Freshness in the matte
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.
Freshness in the evidence
Our source is a peer reviewed observational or laboratory study, recorded as Sugimoto 1995 PMID 7738354; Sitohang 2020 PMID 32983333. You can read it yourself at PubMed 7738354. We grade that as solid support for what the ingredient does.
Freshness and its limits
The research behind Zinc PCA studies the ingredient, not the finished Opuliss product it sits in. It supports what Zinc PCA 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.
