Juglans Regia (walnut) Shell Powder is finely ground walnut shell used as a natural physical exfoliant in scrubs and cleansers to mechanically remove dead surface skin cells. It is valued as a biodegradable alternative to synthetic microbeads.
| Reported effect | How often | Notes |
|---|---|---|
| Microtears and mechanical skin irritation | Common | Irregularly shaped particles can create small abrasions on the skin surface, especially with vigorous use. |
| Redness or transient erythema | Common | Often follows scrubbing, particularly on sensitive or thin skin. |
| Allergic contact dermatitis | Rare | Possible in individuals with tree nut sensitivities, though shell material contains little protein. |
| Worsening of acne or inflammatory lesions | Uncommon | Over-exfoliation may aggravate active breakouts or compromised skin barrier. |
