I already loved the premise of Odacité before my Gua Sha mini-facial: completely clean formulas created by Valerie Grandury, who overhauled her life (and skin) to rid it of toxins, after recovering from breast cancer. She made products for herself and then friends… and beyond. The treatment, which takes place at the Space NK skincare counter, is part facial, part diagnosis. In the 30-minute appointment my skin was cleansed twice, then a bespoke serum was built from three oil blends. In my case, it targeted combination skin, clogged pores and blemishes. The serum was massaged into skin with a large, smooth stone (which I have started using at home). Afterwards, my complexion looked healthier and, almost two weeks on, clearer too. The facial costs £25 (redeemable for product) and can be booked over the phone.
