Hypericum Perforatum Extract

Hypericum perforatum extract, commonly known as St. John's Wort extract, is derived from a flowering plant with a long history in traditional medicine systems across Europe, Asia, and the Middle East. The extract contains several bioactive compounds including hyperforin, hypericin, quercetin, and other phenolic and flavonoid derivatives.In skincare, this extract functions primarily as an antimicrobial and skin-soothing agent. It also has astringent properties, which may help tone the skin, and is used as a skin conditioner and protectant in formulations.

The bioactive compounds in Hypericum perforatum extract—particularly hyperforin and hypericin—are thought to exert antimicrobial effects by disrupting bacterial cell membranes and inhibiting their growth. These same compounds, along with flavonoids, possess antioxidant activity, helping to neutralise reactive oxygen species that contribute to skin ageing and inflammation.The extract's soothing and astringent effects likely stem from its polyphenol content, which can reduce inflammation and provide a mild tightening sensation on the skin. Research into its wound-healing potential is ongoing,…

Hypericum perforatum extract is typically used in formulations at low concentrations (often under 1%) as a supporting ingredient alongside other actives. It works well in toners, serums, and moisturisers aimed at calming or balancing the skin. As with any new ingredient, introduce it gradually and observe how your skin responds over a few weeks. It pairs well with other soothing botanicals and antioxidants.

Generally well-tolerated in topical skincare applications. Some individuals may experience sensitivity. Note that oral St. John's Wort can interact with certain medications; however, topical use at cosmetic concentrations is not known to pose the same systemic risks.
