Silymarin Phytosome® is an original complex between the flavanolignans (mainly silybin, silydianin, silycristin) extracted from Silybum marianum fruits (silymarin extract) and soybean phospholipids in a 1:2 ratio. This complex exhibits enhanced functionality of the flavanolignans resulting in a longer lasting activity and increased effectiveness on the skin. The soothing and protectant activity of the extract is due to the antioxidant properties of the flavanolignans. The soothing activity of silymarin has been shown to be increased by more than 6 times in Silymarin Phytosome® in experimental models. The improvement in the activity of the Phytosome® form, compared to the free active principles, is due to a higher affinity of the complex for skin phospholipids. This not only improves the absorption of the compounds exerting the biological activity, but also increases the duration of the activity as the complex slowly releases the active principle.
