Silymarin, derived from the milk thistle plant, Silybum marianum, is a natural polyphenolic flavonoid. Its main component silybin (silibinin), is considered to be the most biologically active with strong antioxidant properties.[39] In vivo studies have shown photoprotective effects with topically applied silybin prior to, or immediately after, UV irradiation.[40] Thus, there is reasonable evidence to include the compound into sunscreens.
