What skin types is this clay most suitable for, and what precautions should I take?

The mineral composition (silica, iron, magnesium, potassium, calcium) and strong adsorbing capacity make this clay a classic choice for oily, combination, and blackhead-prone skin — it binds surface sebum and impurities without penetrating beyond the stratum corneum. Dry or sensitive skin can still use it, but keep exposure short (5–7 minutes) and always apply a moisturiser afterwards to replenish the hydrolipid film. Avoid the eye area entirely. Never let the mask dry to a hard crust; spritz or rinse while still slightly damp to prevent surface dehydration. A patch test on the inner forearm is recommended before the first use if your skin reacts easily to new products. The product is a pure mineral powder; unlike ready-made cream masks, it contains no preservatives, fragrances, or emulsifiers, so you control exactly what contacts your skin.
