Kaolinite is a naturally occurring hydrated aluminum silicate clay used in skincare to absorb excess sebum, oil, and impurities, and to provide mild cleansing and mattifying effects. It is most commonly found in masks, cleansers, and powders as a base or texturizing agent.
| Reported effect | How often | Notes |
|---|---|---|
| Skin dryness or tightness | Common | Due to its oil-absorbing properties, especially in leave-on or frequently used masks. |
| Mild irritation or redness | Uncommon | Typically transient and more likely on sensitive or already compromised skin. |
| Contact dermatitis | Rare | Allergic reactions to kaolin clay itself are infrequently reported. |
| Respiratory irritation from inhalation | Rare | Relevant mainly to loose powder products; not a concern in cream or gel formulations. |
