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.
Locks In Moisture
Traditional Use
Borage has been used in European herbal medicine and traditional skincare since the Middle Ages for its high content of gamma-linolenic acid (GLA) and linoleic acid. Historically used to soothe irritated skin, reduce inflammation, and support skin barrier function.
