KAOLIN PURIFYING CLAY MASK
A weekly kaolin clay mask for acne-prone and oily skin. Dual pore-purifying clays and activated charcoal adsorb sebum and surface residue, while a microbiome prebiotic complex, Black Tea, and Sage support the skin during wear for a purified, comfortable finish.
Backed by published research · references belowFormulated for Acne Prone, Oily Skin, and Sensitive Skin.
- Kaolin (CAS 1332-58-7) is a fine powder with measured water absorption of 1,000 milligrams per gram, its own weight in water1.
- Montmorillonite, a smectite-group clay, adds a complementary adsorbent profile with higher swelling capacity than Kaolin for pore-area purifying.
- Charcoal Powder (activated carbon), an adsorbent that cleanses via porous-carbon physical adsorption.
Hero mechanism: Kaolin, a 1:1 phyllosilicate clay, purifies through physical adsorption of sebum and surface residue. Full mechanism and citations under Details and references.

- Apply an even layer to clean, dry skin once or twice weekly. Leave on for 5 to 10 minutes. Do not allow the mask to dry to a fully cracked state.
- Rinse thoroughly with lukewarm water.
- The 90 ml format supports roughly 8 to 12 weeks of weekly use.
Are there any side effects?
Patch test recommended for first use. Clay masks may produce a transient tightening sensation during wear that subsides on rinse.
Does it actually work?
Kaolin clay is studied in cosmetics for absorbing excess surface oil, helping this mask leave pores looking cleaner and the complexion more matte and refined.
How do I use it?
Apply an even layer to clean, dry skin once or twice weekly. Leave on for 5 to 10 minutes.
What is this and who is it for?

100% natural origin, 16% organic origin, vegan eligible. No added Parfum. Iron oxide pigments (CI 77491, CI 77492, CI 77499) supply a soft warm finish and are EU-approved cosmetic colourants. Lactic Acid is present at pH-adjuster trace level only and is not an exfoliating active in this rinse-off format. Patch test recommended for first use. Clay masks may produce a transient tightening sensation during wear that subsides on rinse. Avoid contact with eyes. Rinse with water if any product enters the eye.
Kaolin (CAS 1332-58-7) is the foundation clay. Its 1:1 phyllosilicate sheet structure delivers physical adsorption of sebum and surface residue without the expansive swelling of smectite-group clays, with quantified water absorption of 1,000 milligrams per gram1. A 4-week prospective clinical study of a kaolin-bentonite mask in 75 oily-and-combination-skin subjects documented sebum reduction of 68.97% immediately and 29.90% at week 4 by Sebumeter measurement2. That clinical reference is a multi-ingredient formulation, while the Opuliss formula pairs Kaolin with Montmorillonite, Diatomaceous Earth, and Charcoal in a different formula. EU CosIng lists Kaolin with ABSORBENT, OPACIFYING, BULKING, and ABRASIVE (mild) functions.

SCIENCE, MADE VISIBLE
Opuliss begins where the research ends. Every active is named, every claim is traceable, and nothing is left to promise alone.
Morning to night
A RITUAL, CONSIDERED
Each formula stands on its own and belongs to the whole. Layered with intention, morning and night, the routine becomes unmistakably yours.
A twenty four hour rhythm
THE SKIN KEEPS TIME
Skin is not the same at midnight as it is at nine in the morning. Across a single day its temperature, its acidity and the moisture it loses to the air each move on a rhythm of their own. Morning and night are not two routines. They are one, kept in time.
