Perlite sits in our formulas for one job: refining the feel and look of texture. We file it under Smoothing in this glossary because that is the effect its evidence actually supports, not because it is the most flattering label available.

Polish in the mineral

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.

Polish in the evidence

Our source is an industry technical paper from a credentialed source, recorded as EU CosIng (abrasive / bulking mineral). We grade that as supplier and sector evidence, weaker than published research.

Polish and its limits

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