Four Seasons Hotel London at Park Lane has collaborated with Kate Moss’ Cosmoss on an exclusive treatment offered at the hotel spa. The 60-minute Cosmoss Ritual was created by Senior Spa Director Taffryn Ellis, who has included wellness-based practices such as breathwork within the treatment. “We have created a unique experience that not only offers pampering, but also wellbeing solutions that can be embraced and continued beyond The Spa,” said Ellis.
