La Prairie Skin Caviar Essence-in-Lotion is a serum-like lotion that is designed to be used immediately after cleansing and toning, before other serums and moisturisers.  Formulated with active caviar water, the Skin Caviar Essence-in-Lotion immediately improves skin’s hydration, and boost elasticity by plumping from within.  For the first time, La Prairie scientists have found a way to extract the active components of caviar in a steam distillation process, to complement their existing caviar extract derived from classical extraction.  These are combined with La Prairie’s signature cellular complex, which is a cocktail of skin-loving nutrients to energize skin cells and boost skin rejuvenation.
