Silybin

Silybin is a flavonolignan compound extracted from milk thistle seeds (Silybum marianum). It is a naturally occurring antioxidant that has been studied for centuries in traditional medicine and is now incorporated into modern skincare formulations.In skincare products, silybin functions primarily as a skin conditioning agent, working to support the skin's natural protective mechanisms and overall health through its antioxidant properties.

Silybin operates primarily through its antioxidant action, which involves neutralising free radicals—unstable molecules that can damage skin cells and accelerate visible signs of ageing. By reducing oxidative stress, silybin helps protect skin from environmental damage such as pollution and UV exposure.Additionally, silybin is believed to support the skin's natural barrier function and hydration levels, contributing to a more resilient, conditioned complexion.

Silybin is typically found in serums, moisturisers and targeted treatment products. It integrates well into most skincare routines and can be used alongside other actives, though patch testing is advisable if you have particularly sensitive skin. Follow product instructions for frequency, as formulations vary in concentration and intended use.

Silybin is generally well-tolerated and considered safe for topical use. Those with known allergies to plants in the Asteraceae family (including ragweed and chrysanthemum) should approach with caution.
