Illite is a natural clay mineral (a hydrated potassium aluminosilicate) used in skincare for its oil-absorbing and mild cleansing properties, commonly found in masks and cleansers. It helps draw out sebum and impurities while providing trace minerals to the skin surface.
| Reported effect | How often | Notes |
|---|---|---|
Skin dryness or tightness | Common | Due to oil and moisture absorption, especially on dry or sensitive skin with frequent use. |
Mild irritation or redness | Uncommon | Transient, typically resolving after rinsing; more likely with prolonged contact. |
Allergic contact dermatitis | Rare | Possible reactions to trace mineral contaminants rather than the clay itself. |
Respiratory irritation from powder inhalation | Very rare | Relevant mainly when handling loose dry powder, not finished formulations. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
