Silybum Marianum Fruit Extract, also known as Milk Thistle Extract, is derived from the fruit of the Lady’s Thistle plant, scientifically named Silybum marianum (L.), which belongs to the Asteraceae family. This plant is native to the Mediterranean region but is now found in various parts of the world, including North America and Australia. The extract is rich in a group of compounds known as silymarins, which include silybin, silydianin, and silychristin. These compounds are known for their antioxidant properties.
Historically, Milk Thistle has been used for centuries in traditional medicine, primarily for liver health and detoxification. Its use in cosmetics is a more recent development, driven by its potent antioxidant properties and its ability to condition the skin. The transition from medicinal to cosmetic use began as researchers started to explore the benefits of natural plant extracts in skincare, leading to the incorporation of Silybum Marianum Fruit Extract in various beauty products.
The extraction process typically involves harvesting the fruits of the Lady’s Thistle plant, followed by drying and grinding them into a fine powder. This powder is then subjected to a solvent extraction process, often using ethanol or methanol, to isolate the active silymarin compounds. The resulting extract is then purified and standardized to ensure consistent quality and efficacy before being incorporated into cosmetic formulations.
