The extract contains a complex of compounds, including silymarin, which has been used in traditional herbal medicine for centuries. In skincare formulations, it functions primarily as a skin conditioning agent.The extract works at a chemical level through its phytochemical composition. When incorporated into skincare products, its bioavailability and efficacy can be influenced by how it's formulated—for instance, certain complexing agents may affect how well the active…

Milk thistle extract contains bioactive compounds that function as antioxidants. These work by donating electrons to unstable free radicals, potentially preventing oxidative damage to skin cells. The extract also has moisturising properties that help condition the skin barrier.The effectiveness of the extract depends partly on its formulation. Research suggests that how the extract is delivered to the skin—including factors like pH, solubility, and whether it's combined with penetration enhancers—influences how well these compounds reach the skin and remain stable.

Milk thistle extract is typically found in serums, moisturisers, and emulsion-based formulations at low concentrations (often around 1%). It can be incorporated into both morning and evening routines as part of your regular skincare regimen. As with any new ingredient, introduce it gradually and monitor your skin's response, particularly if you have sensitive skin.

Milk thistle extract is generally well-tolerated in skincare products. Those with known sensitivity to plants in the Asteraceae family (such as ragweed or chamomile) should exercise caution, as cross-reactivity is possible.
