How do I mix and apply this clay as a face mask for oily or combination skin? — Siberian clay, toning phytocosmetic 155ml

Mix a small amount of powder — about a teaspoon is enough for one face mask — in a small glass or ceramic bowl. Add water a few drops at a time, stirring with a wooden or silicone spoon, until you get a smooth paste that looks like thick yoghurt. Avoid metal utensils if you prefer; the powder itself is inactive until moistened, but a non-reactive bowl keeps mixing simple.

Apply to cleansed, dry skin with a brush or clean fingertips, leaving a visible 1–2 cm margin around the eyes and mouth. The layer should be even but not thick — just enough to adhere without dripping. Leave it on only until it begins to feel tight; for most people that is roughly 5–10 minutes. If it tightens sooner, rinse immediately. The mask should never crack or form scales before you rinse it.

Rinse well with warm water, using a soft cloth to remove the last residue. Follow with a simple moisturiser or a few drops of facial oil. Because the clay binds sebum and leaves the skin less oily, a moisturising step helps keep the surface comfortable — this is the standard way to finish any absorbent clay mask.

Start with once a week. If your skin tolerates it well, you can increase to a few times per week, as described in the product information. If the skin feels tight after every use, reduce the frequency or shorten the application time. Always avoid the eye area, and never leave the mixture on longer than it stays comfortably moist.
