Youth Reviver combines Seastem and Retinocollagen C, two exclusive and ultra-effective complexes designed to boost the skin's radiance, improve its firmness, and correct wrinkles. By combining the two complexes from Initial Youth (Retinocollagen C) and Expert Youth (Seastem), the Youth Reviver mask revives and remobilizes skin cells to offer them a second youth. The skin seems rejuvenated and better prepared to fight signs of ageing. How to use: Once or twice a week, apply a medium layer to face and neck, avoiding the eye contour area. Leave on for 10 to 15 minutes, then rinse.
