Functions
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Fragrance
Added for scent. Can be natural or synthetic. Common irritant and allergen — one of the top reasons people react to products.
Masks Odor
Antioxidant Protection
Reduces Inflammation
Locks In Moisture
Traditional Use
Hazelnut oil has been used for centuries in European and Mediterranean skincare as a light emollient and skin conditioning oil. Traditionally applied to maintain skin softness and to support the skin barrier.
