What it is
Juglans Regia Seed Extract is obtained from the kernels of the common walnut. Walnut kernels are rich in lipids and polyphenols, and the extract is used as a conditioning, softening botanical within the supporting ingredient blend of skincare and sun-care products. It is typically present at modest levels alongside other plant extracts.
Safety & warnings
Generally well tolerated at cosmetic use levels. Walnut is a recognized tree-nut allergen, so people with tree-nut allergies may prefer to patch test or avoid it. As with most botanical extracts, occasional contact sensitivity is possible. This seed extract should not be confused with crushed walnut-shell powder used as a physical scrub.
Origin & sourcing
Natural; prepared from the seeds (nutmeats) of Juglans regia, a walnut species widely cultivated across temperate regions of Europe and Asia.
Questions everyone asks
Is walnut seed extract the same as a walnut shell scrub?
No. This is a liquid extract used for skin conditioning, whereas walnut-shell powder is a granular physical exfoliant; they are different ingredients with different roles.
Should nut-allergic users avoid it?
Walnut is a tree nut, so those with tree-nut allergies may choose to patch test or avoid products containing it as a precaution.
