Walnut Shell Powder is a gentle, natural exfoliant made from finely ground walnut shells. It provides mild physical exfoliation to help remove dead skin cells and reveal smoother, brighter skin. Popular in UK skincare and bath products, it offers an eco-friendly alternative to plastic microbeads.

How it works in skincare

In cosmetics and skincare, walnut shell powder functions as a natural abrasive that delivers controlled mechanical exfoliation. The finely milled particles buff away dull surface cells and impurities without the harshness of synthetic scrubs, leaving skin feeling smoother and more refined. It is commonly incorporated into facial scrubs, body polishes, hand washes and soap bars where a gentle yet effective physical exfoliant is desired.
