The new Ole Henriksen Cold Plunge Pore Remedy Moisturizer (£36) is inspired by the "cold plunge" step of the Scandinavian sauna cycle (so you hop into a icy cold bath, and yes it's as torturous and refreshing as it sounds). The oil-free moisturiser actually features a slushy texture that's almost like crushed ice, and provides an invigorating splash of hydration. It's especially good for those with oily or spot-prone skin, as it contains salicylic acids to help clean out clogged pores.
