Functions
Fragrance
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.
Skin Protecting
Reduces Inflammation
Wound Healing
Shields skin from damage
Traditional Use
Used in traditional Persian and Arabic medicine for anxiety and insomnia. The essential oil has been employed in European perfumery and skincare since the 16th century for its uplifting and skin-conditioning properties.
