Red clay is an iron oxide-rich kaolinite or illite clay used in masks and cleansers to absorb excess sebum, draw out impurities, and provide mild exfoliation. It also imparts a natural reddish color to formulations.
| Reported effect | How often | Notes |
|---|---|---|
| Skin dryness or tightness | Common | Due to sebum and moisture absorption, especially with frequent use on dry skin. |
| Mild irritation or redness | Uncommon | Transient, typically from over-drying or prolonged contact. |
| Allergic contact dermatitis | Rare | Possible sensitivity to clay minerals or trace components. |
| Trace heavy metal exposure concerns | Very rare | Naturally sourced clays may contain trace metals; cosmetic-grade purification minimizes this. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
