Antioxidant
Fights free radicals — the unstable molecules from UV, pollution, and stress that break down collagen and cause premature aging.
Conditions Skin
Reduces Inflammation
Wound Healing
Softens & Smooths
Traditional Use
American hazelnut oil has been used traditionally by Native American peoples for skin nourishment and as a massage oil. The nuts were valued for their nutritional and protective properties.
