What is Thuja Koraiensis Extract?
Thuja Koraiensis Extract is a natural ingredient derived from the whole plant of Thuja koraiensis, a species of coniferous tree in the cypress family, Cupressaceae. This tree is native to the mountainous regions of Korea, hence the name ‘Koraiensis’. The extract is also known by other names such as Korean Thuja Extract and Thuja Orientalis Extract.
The use of Thuja Koraiensis in cosmetics is relatively recent, but the plant itself has a long history of use in traditional Korean medicine. It was often used for its antioxidant properties and to promote skin health. The extract is obtained by processing the whole plant, including the leaves, bark, and wood, through a method known as steam distillation. This process helps to preserve the beneficial compounds present in the plant, including flavonoids and phenolic compounds, which are known for their antioxidant and skin conditioning properties.
While there are other plant extracts used in cosmetics for their antioxidant and skin conditioning benefits, Thuja Koraiensis Extract stands out due to its unique composition. It contains a high concentration of flavonoids and phenolic compounds, which are potent antioxidants that can help to protect the skin from oxidative stress. This makes it a valuable ingredient in skincare products designed to combat the signs of aging.
Thuja Koraiensis Extract is typically used in a variety of cosmetic products, including moisturizers, serums, and anti-aging creams. Its antioxidant and skin conditioning properties make it a versatile ingredient that can help to improve the texture and appearance of the skin, while also providing protection against environmental stressors.
