La Mousse is a luxurious, foaming facial cleanser, infused with rare moonlight flower cryoextract, that features a dual cleanse and care technology to gently purify and exfoliate for soft, smooth, radiant skin. The beating heart of Clarins' Precious skincare collection, the rare moonlight flower, blooms only one night a year and must be hand picked and immediately flash frozen at -320.8°F to preserve the potency of its properties. This cutting-edge process harnesses the precious moonlight flower cryoextract, a powerful ingredient that is exclusive to Clarins.
