Because of its emollient properties and free radical scavenging activities, walnut oil is commonly used in dry skin creams as well as antiaging products or even for formulations that lighten under eye dark circles.​

The high amount of linoleic acid makes walnut oil unique.
Linoleic acid, better known as Omega 6, is an "essential" fatty acid that the body cannot produce. A lack of omega-6 can lead to dry skin or allergies. In the skin, linoleic acid is part of ceramides and helps maintain the lipid balance of the epidermis and the proper connection of skin cells. It also prevents water loss from the skin, while providing nourishing and softening effects. 

Historically Walnut oil has been used in products to combat hair loss with the help of Omega-3 fatty acids, which prevent cellular damage, and it helps keep the scalp clean by removing all the dirt from it, making this oil perfect for those that are looking to create a hair care range.
