What is Juglans Regia (Persian Walnut) Leaf Extract?

Juglans Regia Leaf Extract comes from the leaves of the Juglans regia tree, commonly known as the Persian or English walnut, native to regions in Central Asia and widely cultivated globally. This botanical extract is rich in tannins, flavonoids, and polyphenols, which contribute to its functional roles in cosmetics. Primarily used in toners, cleansers, masks, and conditioning products, it acts as an astringent by temporarily tightening skin surface through protein contraction, while its antioxidant components help protect against oxidative stress. As a skin conditioning agent, it supports moisture retention and smoothness. The extract also provides mild exfoliation in scrub formulations and aids in odor masking or fragrance enhancement due to its natural aromatic profile. Overall, it enhances product texture, sensory feel, and skin preparedness for subsequent treatments.

Fragrance ingredient
Contributes scent character and/or masks base odors, shaping the overall sensory experience of the formula (subject to allergen and IFRA considerations).
Skin conditioning agent

Cleansing agent
