Juglans Regia (Persian Walnut)
What is Juglans Regia (Persian Walnut)?
Juglans Regia is the botanical name for the Persian walnut tree, native to regions like Central Asia. In cosmetics, it typically refers to the finely ground shell of the walnut fruit, harvested after nut extraction. This plant-derived powder serves as a physical exfoliant in products such as facial and body scrubs. It functions by mechanically sloughing off dead surface skin cells through gentle abrasion during cleansing, helping to reveal smoother skin texture. Valued for its renewable sourcing and eco-friendly breakdown compared to microbeads, it appears in rinse-off formulations where particles are rinsed away. The shell's natural composition includes cellulose and lignin, contributing to its polishing effect without chemical additives.
