DUOLYS CE Serum

INTENSIVE ANTIOXIDANT SERUM

The greatest ally of dull skin, this serum offers unequalled efficacy thanks to its high content of pure vitamin C, a potent antioxidant. For people over the age of 30 years

Its compartmentalized double formula enables Duolys CE to simultaneously combat all signs of ageing: wrinkles and lines, loss of firmness, brown spots and dullness. The 15% pure vitamin C blocks the action of free radicals, reinforces collagen production and revives complexion's radiance. To preserve its stability, the vitamin C is isolated in a protective compartment. Each active substance thus delivers the full power of its anti-ageing action on the face, neck and décolleté, while remaining gentle on the more fragile skins. The complexion is unified and radiant, wrinkles fade, the face is more beautiful.

  •  A high pure vitamin C content (15%), whose efficacy against skin ageing has been demonstrated
  •  Innovative duo packaging for maximum efficacy 
  •  Leaves the skin firmer
