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.
Antioxidant
Fights free radicals — the unstable molecules from UV, pollution, and stress that break down collagen and cause premature aging.
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Hair Conditioning, Skin Conditioning, Anti
Inflammatory, Moisturizing, Boosts Collagen, Softens and smooths skin, Softens and detangles hair
Traditional Use
Grapefruit seed extract gained popularity in the 1970s as a natural antimicrobial agent. Modern skincare adopted it for its high antioxidant content, though traditional use of grapefruit itself is relatively recent compared to other citrus fruits.
