Functions
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Antioxidant
Fights free radicals — the unstable molecules from UV, pollution, and stress that break down collagen and cause premature aging.
Softens & Smooths
Traditional Use
Evening primrose seed oil, used in European folk medicine since the 17th century for hormonal balance and skin health; historically applied topically for inflammatory skin conditions.
