Prunus Amygdalus Dulcis (Almond) Shell Powder is a finely milled natural powder derived from almond shells, used primarily as a mechanical exfoliant and abrasive in scrubs and cleansers to help remove dead surface skin cells. It is a non-active, naturally derived formulation additive valued for being biodegradable.
| Reported effect | How often | Notes |
|---|---|---|
Mechanical skin irritation or microtears | Uncommon | Coarse or irregular particles can cause micro-abrasions, especially with vigorous scrubbing or on sensitive skin. |
Redness and transient sensitivity | Uncommon | Physical exfoliation may leave skin temporarily reddened or tender. |
Allergic contact dermatitis | Rare | Possible in individuals with tree nut sensitivities, though shell-derived material contains minimal protein allergen. |
Exacerbation of inflammatory acne or rosacea | Rare | Abrasive use can aggravate active breakouts or sensitive conditions. |
