Rosemary leaf extract is an active ingredient derived from the Rosmarinus officinalis plant. In anti-aging face care, it is used at a concentration of 2% for its antioxidant, anti-inflammatory and toning properties.

Free radicals are unstable molecules produced by our body when exposed to factors such as pollution, UV rays, stress and aging. These free radicals can cause damage to our skin cells, thus accelerating the skin aging process. Rosemary leaf extract contains phenolic compounds and rosmarinic acids which act as antioxidants, protecting the skin against free radicals and reducing the signs of aging.

Rosemary leaf extract also helps soothe and reduce inflammation in the skin with its anti-inflammatory properties. Chronic inflammation is a major cause of premature skin aging, and regular use of rosemary leaf extract helps prevent these negative effects.

Finally, rosemary leaf extract tones the skin by stimulating the production of collagen and elastin. These proteins are essential for maintaining the firmness and elasticity of the skin, and their production naturally decreases with age. By stimulating their production, rosemary leaf extract improves skin texture and reduces the appearance of fine lines and wrinkles.
