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.


Innovative DUO packaging to ensure optimal formula stability and efficacy, non-oily, non-sticky, excellent make-up base
