Fans of Aromatherapy Associates will be thrilled to learn that the British beauty brand has opened a new flagship in Knightsbridge. You’ll find all your favorite creams, skincare, and bath oils in the retail store, and you can even create your own bespoke oil blends from the “ingredients bar”- under the watchful eye of the brand’s expert aromatherapists. You can experience "mini-treatments" in the boutique, or for more lavish spa indulgences (like aromatherapy massage, the City Stress Buster, or the Essential Rose Facial), head downstairs to one of three luxe treatment rooms. Don’t miss the "pretty nibbles" (cookies, macarons), says Time Out's blog, served in a relaxation room after your de-stressing spa treatment.
