After more than 30 years of clinical studies, CHANEL Science developed the ÉCLAT PREMIER beauty ritual, a line of skincare and makeup designed to help preserve and revive skin's first radiance. ÉCLAT PREMIER La Mousse is the key first step in your skincare routine, designed to cleanse the skin and fully revive its luminosity. ÉCLAT PREMIER La Mousse cleanses the skin, improves skin quality, and leaves the complexion more even, helping to preserve and revive its radiance. It removes impurities from the skin, including pollution particles and UV filters, all while protecting the skin moisture barrier. The cleanser's rich cream texture transforms into a generous foam on contact with water. From the very first application, skin is immediately and intensely purified. Day after day, skin appears refined and looks brighter.
