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.
