Life Plankton Essence is the first step of the beauty routine to nourish dry skin. For the first time, Life Plankton, Biotherm's core natural ingredient is infused in this essence at its highest concentration. Urban life and pollution slow down skin's self-defense, making skin weak, rough, and dry. This powerful essence regenerates skin from urban aggressions: in 8 days, see and feel newborn skin: soft, quenched with hydration, more resilient, and visibly younger. Key Ingredients: Life Plankton probiotic fraction: A patented regenerating probiotic fraction, proven to improve skin metabolism and heal skin from urban accelerated aging. 100% natural ingredient. Sourced in the French Pyrenees, amplified by bioscience. Infused in all Biotherm products.
