HISTORY
Goji berries, known as wolfberries, have been treasured in traditional Chinese medicine for centuries, originating in the Ningxia region during the Tang Dynasty (618-907 AD). Revered for their health benefits, including longevity and vitality, they were famously consumed by Li Qing Yuen, who reportedly lived to 256 years old. During the Nara period (710-794 AD), Japanese monks brought goji berries to Japan, integrating them into Kampo medicine, where they continued to symbolize health and well-being. Today, goji berry extract is celebrated in modern skincare for its high levels of antioxidants, vitamins, amino acids, polysaccharides, and trace minerals, offering benefits such as anti-aging, hydration, brightening, anti-inflammatory properties, and collagen production.
SCIENCE
Goji berries, known as wolfberries, have a storied history in traditional Chinese medicine, originating in the fertile Ningxia region during the Tang Dynasty (618-907 AD). These vibrant red berries were believed to enhance vitality, prolong life, and improve overall health, famously consumed by Li Qing Yuen, who reportedly lived to the age of 256 years. During the Nara period (710-794 AD), Japanese monks studying in China brought goji berries back to Japan, integrating them into Kampo medicine. Over the centuries, goji berries maintained their esteemed status in Japan, symbolizing health and well-being.
Modern science has confirmed the potent benefits of goji berries, particularly in skincare. The extract is packed with a plethora of nutrients, including antioxidants, vitamins, amino acids, polysaccharides, and trace minerals, making it a powerhouse ingredient for skin health. The high levels of antioxidants, such as vitamin C, beta-carotene, and zeaxanthin, help neutralize free radicals, reducing oxidative stress and preventing premature aging.
Amino acids in goji berries play a crucial role in skin repair and regeneration, maintaining elasticity and firmness. Polysaccharides, unique to goji berries, enhance hydration and improve the skin's barrier function, keeping it plump and moisturized. Additionally, the trace minerals found in goji berries, such as zinc, copper, selenium, and iron, are essential for maintaining healthy skin and promoting collagen synthesis.
The proven benefits of goji berry extract in skincare are extensive. Studies have shown that it can significantly reduce the appearance of fine lines and wrinkles, combatting the damaging effects of UV radiation and environmental pollutants. The extract's ability to retain moisture enhances hydration levels, making it particularly beneficial for dry and dehydrated skin types. Furthermore, the high vitamin C content aids in brightening the skin tone, reducing dark spots, and promoting an even complexion.
Goji berry extract also boasts anti-inflammatory properties that soothe irritated skin and reduce redness, making it suitable for sensitive skin. The trace minerals and amino acids stimulate collagen production, improving skin elasticity and reducing sagging. These multifaceted benefits make goji berry extract a valuable addition to any skincare regimen.
In terms of facts and figures, goji berries contain up to 500 times more vitamin C than oranges by weight, making them a superior source of this vital nutrient. Their ORAC (Oxygen Radical Absorbance Capacity) value of 25,300 indicates a strong antioxidant capacity. A study published in the "Journal of Cosmetic Dermatology" found that a goji berry extract cream significantly improved skin hydration and elasticity after 30 days of use.
