About Product Introduction
Oleuropein powder is extracted from the dried leaves of olive trees. Among the substances contained in olive leaves, oleuropein is identified as the most active core active ingredient, which is a non-toxic secoiridoid glycoside compound. Oleuropein exhibits multiple effects, including anti-inflammatory, antifungal, antiviral, and antioxidant properties, as well as anticancer and blood glucose-lowering effects. Leveraging these excellent active properties, oleuropein powder is widely used in fields such as pharmaceuticals, cosmetics, and health supplements, and has become a preferred raw material for various industries in the R&D of high-quality products.

Repair Effects of Olive Leaf Extract Oleuropein Powder
1. Protective Antioxidation, Safeguarding Cell Vitality
It can resist free radical damage induced by ultraviolet rays. In experiments, skin cells coated with pure olive leaf extract remained almost intact after 24 hours, effectively maintaining the viability of keratinocytes and fibroblasts. Meanwhile, it can prevent the decomposition of cell membrane lipids caused by ultraviolet rays. Verified by fluorescence analysis, it can significantly inhibit peroxidation reactions, providing high-level protection for fibroblasts.

2. Promoting Collagen Metabolism and Repairing Skin Structure
Oleuropein can activate fibroblasts to synthesize collagen. Experiments using proline as an indicator show that after adding its extract, the amount of newly synthesized collagen is significantly increased, helping the skin maintain elasticity. It can also resist glycation reactions; 37℃ test-tube experiments confirm that it can reduce the derivatives formed by lysine and glucose-6-phosphatase, and avoid skin sagging and wrinkles caused by collagen cross-linking.

3. Inhibiting Collagenase and Delaying Skin Aging
Oleuropein indirectly reduces collagenase secretion. Studies conducted on keratinocyte cultures supplemented with the extract and exposed to UVA/UVB radiation have demonstrated its ability to suppress ultraviolet-induced signaling in keratinocytes, thereby preventing fibroblasts from being stimulated to produce collagenase. With combined protective, reparative, and anti-enzymatic properties, oleuropein—thanks to its antioxidant and anti-inflammatory characteristics—is valuable in pharmaceutical and health product applications, particularly in skincare for its moisturizing and rejuvenating effects.
