1. Antioxidant or photoprotective

Oleuropein can help improve the skin's own ability to scavenge DPPH free radicals, fight lipid peroxidation during the day, and help the skin resist the excessive generation of free radicals caused by UV stimulation, and prevent the decomposition of skin membrane lipids by ultraviolet rays, inhibit the secretion of collagenase, and prevent damage to skin elasticity caused by ultraviolet rays.

2. Anti-inflammatory repair

Olive oil extract can increase the activity of macrophages, engulf bacteria in the early stage of inflammation, and inhibit the release of histamine, thereby reducing the expression of various inflammatory factors and exerting anti-inflammatory effects. In the later stage of the development of inflammation, it can theoretically improve the redness caused by inflammation and the acne marks left by acne by promoting cell proliferation, collagen production, etc., accelerating wound healing, reducing the rate of epidermal water loss (improving the barrier), etc.

3. Antibacterial

In some experiments, oleifera oleifera extract showed the inhibition of various bacterial activities, and the activity of P. acnes was reported, so it can also appear in some anti-acne products.

4. Other functions

For example, anti-aging or whitening, anti-glycation and so on on the side. Since olive oil itself fights against free radicals, it shows the protection of skin elasticity and prevents excessive production of collagenase, so it also appears in some anti-aging products. Secondly, the luteolin in olive oil itself also has the ability to inhibit saccharification. Therefore, it can also help the skin to resist aging while improving the phenomenon of dull and yellowing.

And its characteristics of stimulating the activity of macrophages can also help phagocytose melanocytes, so it also has a certain whitening auxiliary function, and cooperates with some ingredients to prevent melanin deposition after inflammation.

Because the composition of the whole olive extract is relatively complex, it can show many effects in addition to our common repairing and anti-inflammatory. Depends on their respective product formulations.
