New wellness spot Elu Spa brings a luxurious and relaxing experience to Soho with massages and facials in a Scandi-inspired atmosphere. The hygge oasis opened this summer with a signature Gemstone Facial. Following cleansing and a series of moisturising serums, a therapist will massage your skin with hot jade rollers, then drape a mask made of rose quartz, jade, amethyst quartz, black obsidian or clear quartz beads across your face for a cooling, calming and detoxifying effect. The overall effect is said to improve lymphatic drainage in the face and reduce swelling. Pre- or post-flight, this could be a worthwhile pick-me-up for your skin.
