Augustinus Bader's The Essence Exfoliating Toner (£65) is one useful bottle to have as part of your skin-care routine. The multi-purpose liquid is a pore-clearing toner, an at-home peel, and a hydrating essence in one single step. In addition to the brand's proprietary TFC8 amino acid complex that's in all of its products (and promises to have strong reparative properties), the essence also includes three hydroxy acids — phytic, salicylic, and gluconalactone — as well as fermented wasabi and white peony flower, the combination of which gently exfoliates the skin's surface and clears out pores (that would be the salicylic acid), while still hydrating and repairing damaged cells.
