Walnut shell powder
On the label: Juglans Regia Shell Powder · Exfoliant
What it is
Ground walnut shell, a physical scrub particle; sharper than jojoba beads, which is the long-running argument over face scrubs.
Exfoliants: Exfoliants remove dead cells from the surface, by chemistry (acids, enzymes) or by rubbing (physical scrubs).
In the research
3 PubMed papers mention it with skin, cosmetics or hair; the three most recent:
- Utilization of By-Products from Livestock: Study on the Mechanical and Thermal Properties of Biodegradable Containers Made with Pork Skin Gelatin Polymer · Foods (Basel, Switzerland), 2022
- Analysis of Food Storage Stability of Biodegradable Containers Made of Pork Skin Gelatin Polymer with Walnut Shell Powder · Polymers, 2022
- Dirt-binding particles consisting of hydrogenated castor oil beads constitute a nonirritating alternative for abrasive cleaning of recalcitrant oily skin contamination in a three-s · The British journal of dermatology, 2010
A paper is a paper, not a verdict: titles are listed so you can read them, and a study on cells or mice says little about a cream on a face.
