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.
Antioxidant
Fights free radicals — the unstable molecules from UV, pollution, and stress that break down collagen and cause premature aging.
Conditions Skin
Locks In Moisture
Fights Bacteria
Traditional Use
Hazelnut oil has been used traditionally in North America and Europe for its light texture and ability to condition skin without heaviness, valued for its fatty acid profile.
