Walnut, specifically crushed walnut shells or powder, is a natural exfoliant often used in skincare products for its abrasive texture. It can be found in various forms like ground walnut shells or finely milled walnut powder, depending on the desired level of exfoliation. Walnut shell powder is commonly used in physical exfoliants like face and body scrubs to help remove dead skin cells to create a smoother, more polished skin texture. But, because of concerns about its potential to cause skin irritation and damage, many skincare experts and brands have shifted to promote healthier, less abrasive exfoliation methods like chemical exfoliants and non-abrasive physical exfoliants.
Juglans Regia (Walnut) Shell Powder
Walnut shell powder is a natural material derived from the ground shells of the walnut tree (juglans regia).
Walnut shell powder can be abrasive and harsh on skin, especially on delicate facial skin. It has the potential to cause microtears or damage if used too aggressively, which can lead to irritation and redness.
Removes Dead Skin Cells
Walnut shell powder's abrasive texture can help physically remove dead skin cells for a smoother, more youthful complexion.
Improves Skin Texture
Regular use of walnut-based exfoliants can contribute to a refined skin texture and reduce the appearance of roughness and unevenness.
Improves Product Absorption
Walnut shell powder removes dead skin cells which can allow for better absorption and effectiveness of other skincare products applied afterward.
