Le Serum, infused with rare moonlight flower cryoextract and enriched with a trio of biomimetic peptides, visibly lifts, firms and smooths skin, delivering the appearance of more defined facial contours. 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.
