The Dorchester Collection hotel has just become one of only two places in the UK where you can get a La Prairie facial, and we were first through the door to try it. 45 Park Lane has landed La Prairie as its new spa partner, and with it, a menu of exclusive treatments you can currently only get here and at its sister hotel, The Dorchester, next door. From there you’re guided into one of three sensory concepts, Lakes, Mountains or Forests, each built out through scent, sound and touch to match the Swiss landscapes La Prairie takes its cues from. There’s a proper lap pool, sauna, steam room and a massive chill-out zone all tucked away underground with the changing rooms, so you forget entirely that Park Lane traffic is happening a few floors above you.
