Rare white truffle for anti-aging, neutralizing free radicals, and providing long-lasting anti-wrinkle and firming effects
We utilize lactic acid bacteria as an expression system that is safe, does not produce endotoxins, and does not contain antibiotic resistance genes. The expressed exogenous active ingredient mixture does not require purification and can be directly applied to skin care along with the bacterial cells.
White truffle (scientific name: Tuber magnatum), also known as Italian white truffle, is a rare fungus belonging to the genus Tuber in the family Tuberaceae. Along with black truffle, it is hailed as "underground gold."
White truffle extract is an active ingredient complex isolated from the rare fungus white truffle through specific extraction processes (such as solvent extraction and enzymatic hydrolysis). Its core active substances include polysaccharides, amino acids, polyphenols, vitamins (such as B vitamins), and various trace elements. It is widely used in skincare and health supplements, with skincare efficacy being a primary research focus.

Tuber magnatum extract is frequently used as an active ingredient in skincare products. Its effects on the skin are primarily based on the characteristics of its components (such as polysaccharides, amino acids, and antioxidants) discovered through modern research. Specific effects and mechanisms are as follows:
Core Effects and Mechanisms
1. Antioxidant and Anti-aging
Effects: Reduces free radical damage, delays skin aging, and improves fine lines and dullness.
Mechanism: Tuber magnatum contains polyphenols, vitamins (such as B vitamins), and polysaccharides, which can eliminate reactive oxygen species (ROS) generated by ultraviolet radiation and pollution, reducing the damage of free radicals to collagen and elastin fibers. Simultaneously, it can activate the activity of antioxidant enzymes in the skin (such as superoxide dismutase SOD), enhancing the skin's own antioxidant capacity, thereby delaying the sagging and fine lines caused by collagen loss.
2. Moisturizing and Barrier Repair
Effects: Increases skin hydration, improves dryness and sensitivity, and enhances the skin barrier function.
Mechanism: The natural polysaccharides and amino acids (such as proline and glycine) in the extract have excellent water absorption and retention capabilities, forming a breathable moisturizing film on the skin surface to reduce moisture evaporation. Simultaneously, these components promote the synthesis of ceramides and cholesterol in the stratum corneum, helping to repair the damaged stratum corneum barrier, reducing the impact of external stimuli (such as dryness and pollutants) on the skin, and alleviating sensitivity and redness.
3. Brightening Skin Tone and Improving Dullness
Effects: Reduces pigmentation, improves skin transparency, and improves uneven skin tone.
Mechanism: Some studies suggest that the extract can reduce melanin production by inhibiting the activity of tyrosinase in the skin (tyrosinase is a key enzyme in melanin synthesis); at the same time, its antioxidant properties can accelerate skin metabolism and promote the shedding of melanin-containing dead skin cells, thereby making the skin tone brighter and more even, and reducing dullness.
4. Soothing and Anti-inflammatory
Effects: Relieves skin inflammation, reduces sensitivity, redness, and itching.
Mechanism: The active ingredients in the extract (such as specific amino acids and polysaccharides) can regulate the release of skin inflammatory factors (such as IL-6 and TNF-α) and inhibit inflammatory signal transduction; at the same time, they can enhance the skin barrier's resistance to irritants, and have a certain soothing effect on sensitive skin and seasonal redness caused by barrier damage.
