Duolys C.E. Intensive Anti-oxydant Serum-15ml

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.
