Inspired by the dual water and oil nature of the skin, this iconic two-phase formula delivers the perfect ratio of water soluble (hydric) and oil soluble (lipidic) ingredients. Once dispensed, the two concentrates combine into one powerful serum that is easily absorbed into the skin to effectively target all visible signs of aging. Perfect for all ages, all ethnicities, all genders, and all skin types—even the most sensitive. Follow with your Multi-Active, Extra-Firming, Super Restorative, or Nutri-Lumière routine to boost your anti-aging results.
