Olive fruits and olive leaves are rich in oleuropein. After more than 100 years of research, it has been found that olive leaf extract oleuropein has a variety of pharmacological and biological activities, such as anti-inflammatory, anti-microbial, anti-oxidation, anti-tumor, anti-cancer and hypoglycemic activity. Its antioxidant effect is twice that of green tea and grape seed extract, and five times that of vitamin C. Oleuropein is a powerful antioxidant that protects the human body from free radicals and oxidative damage, can delay aging and promote health.
Antioxidant effects of Olive Leaf Extract Oleuropein
Oleuropein can maintain the viability of skin cells
Ultraviolet rays can cause the formation of free radicals, which can damage skin cells and even cause cell death. The use of cosmetics containing oleuropein can effectively protect the skin.

Ultraviolet rays can also cause the breakdown of cell membrane lipids, which is a peroxidation reaction. Oleuropein can effectively prevent peroxidation, thereby highly protecting fiber cells.
Repair and promote collagen synthesis
In the process of skin aging, the ability to synthesize glial protein gradually declines, and fiber cells can only produce a small amount of glial protein. And oleuropein can significantly promote the production of glial protein in fibroblasts.
Anti-glycan reaction
Oleuropein can effectively resist the glycan reaction and delay the skin’s sagging and aging. The glycan reaction phenomenon is a reaction that occurs in the cell membrane. It will cause the reticulation of collagen, so that the collagen protein loses its original elasticity, and the skin appears sunken, that is, wrinkles. This phenomenon gradually increases with age.
Anti-colloid enzymatic
Gliamase is an enzyme produced by fiber cells under the influence of free radicals. Under the irradiation of ultraviolet light, keratinocytes will release some information to stimulate fiber cells to produce glialase. Oleuropein indirectly reduces the secretion of collagenase by inhibiting the production of “information” in keratinocytes caused by ultraviolet rays. It reduces the production of skin keratin and makes the skin smooth and bright.
Oleuropein is precisely because of the strong antioxidant properties of oleuropein that more and more skin care products choose to use it as a cosmetic raw material.
