Silybum Marianum Seed Oil
What is Silybum Marianum Seed Oil?
Silybum marianum seed oil is a natural vegetable oil obtained by cold-pressing the seeds of the milk thistle plant (Silybum marianum), a member of the Asteraceae family native to the Mediterranean region. This pale yellow oil is rich in essential fatty acids, particularly linoleic acid, along with oleic acid and natural tocopherols. In cosmetic formulations, it belongs to the emollient and skin conditioning category, commonly found in moisturizers, serums, and facial oils. It functions by creating a lightweight barrier on the skin's surface that helps retain moisture, enhances suppleness, and improves overall texture without clogging pores. Its non-comedogenic nature makes it suitable for various skin types, supporting the skin's natural barrier function through its lipid composition that mimics human sebum.
