Formula IngredientAntioxidantINCI: Rosmarinus Officinalis Leaf Extract
Rosmarinus officinalis leaf extract is derived from the leaves of the rosemary plant (Lamiaceae family). It is rich in rosmarinic acid, flavonoids, phenolic acids, and diterpenes, which give it potent antioxidant and anti-inflammatory properties. In cosmetics it functions as a skin conditioning agent, antimicrobial, and natural antioxidant to help protect both the skin and the product formula from oxidative degradation.
