What is Kukui Nut Oil?
Kukui Nut Oil is extracted from the nuts of the kukui tree (Aleurites moluccanus), also known as the candlenut tree. Native to Hawaii and other tropical regions, the kukui tree holds cultural and medicinal significance in Hawaiian tradition.
The oil is typically cold-pressed from roasted or dried kukui nuts. It has a light texture, mild nutty aroma, and quick-absorbing properties, making it ideal for skin and hair care.
