Silybum Marianum (Blessed Thistle) Seed Extract
What is Silybum Marianum (Blessed Thistle) Seed Extract?
Silybum Marianum Seed Extract comes from the seeds of the milk thistle plant (Silybum marianum), a thistle-like herb from the Asteraceae family native to Europe and Asia. In cosmetics, it serves as a skin conditioning agent, helping to preserve skin's softness, smoothness, and suppleness. The extract is valued for its silymarin content, a group of flavonoids with antioxidant properties that neutralize free radicals from environmental exposures. It works in formulations like serums, creams, and toners by supporting the skin's natural barrier, promoting a balanced feel, and contributing to overall skin resilience. Typically incorporated at low levels, it aligns with natural skincare trends, drawing from the plant's traditional use in herbal remedies adapted for topical application.
