What is Hypericum Perforatum (St. John's Wort) Extract?

Hypericum Perforatum Extract comes from the Hypericum perforatum plant, commonly known as St. John's Wort, a perennial herb with yellow flowers native to temperate regions of Europe, Asia, and North America. The extract is typically prepared by macerating or solvent-extracting the flowering tops, leaves, and stems, yielding a concentrate rich in flavonoids, hyperforin, and hypericin. In cosmetic products like creams, toners, serums, and hair treatments, it functions mainly as a multifunctional botanical active. It conditions skin by enhancing barrier integrity and moisture retention, acts as an astringent to temporarily tighten surface layers for a refined feel, and provides antimicrobial support to limit bacterial proliferation. Its soothing qualities help promote skin calmness, while tonic effects refresh and prep the complexion, making it suitable for formulations targeting comfort and balance.
