Silybum Marianum Seed Extract is derived from the seeds of the Lady’s Thistle, scientifically known as Silybum marianum (L.), which belongs to the Asteraceae family. This plant is also commonly referred to as milk thistle. The extract is rich in a group of compounds called flavonolignans, collectively known as silymarin, which includes silybin, silydianin, and silychristin. These compounds are known for their antioxidant properties.
Historically, milk thistle has been used for centuries in traditional medicine, particularly for liver health. Its use dates back to ancient Greek and Roman times, where it was employed to treat a variety of ailments. The transition from medicinal use to cosmetic applications began as the skincare industry started to recognize the potential benefits of its antioxidant properties for skin health.
The process of making Silybum Marianum Seed Extract typically involves harvesting the seeds of the milk thistle plant, followed by drying and grinding them into a fine powder. This powder is then subjected to an extraction process, often using solvents like ethanol or methanol, to isolate the active compounds. The resulting extract is then purified and standardized to ensure consistency and efficacy before being incorporated into cosmetic formulations.
