What It Does
Rosmarinus Officinalis Leaf Extract is derived from the aromatic leaves of the Mediterranean rosemary plant and contains powerful polyphenolic compounds including rosmarinic acid, carnosic acid, and carnosol. Formulators prize this extract for its exceptional antioxidant potency—often comparable to synthetic antioxidants like BHT—making it valuable for both product preservation and skin protection against oxidative stress. Its natural antimicrobial properties and pleasant herbal scent make it a multifunctional ingredient in natural and conventional formulations alike, particularly in anti-aging and protective skincare products.
