Functions
Perfuming
Added for scent. Can be natural or synthetic. Common irritant and allergen — one of the top reasons people react to products.
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.
Traditional Use
Found naturally in essential oils like pine and lavender, terpineol has been used in traditional aromatherapy and herbal medicine for centuries. Used in cosmetics and fragrances for its fresh, piney scent and historically attributed antimicrobial properties.
