Thanks to a comprehensive combination of potent active substances, this serum combats various signs of ageing and protects against free radicals. For people over the age of 40 years.

Its compartmentalized double formula enables Duolys HYAL to simultaneously combat all signs of ageing, with emphasis on firmness and moisturisation. The 5% pure vitamin C, combined with vitamin E and hyaluronic acid, blocks the action of free radicals, reinforces collagen production, moisturises and revives complexion's radiance. To preserve its stability, the vitamin C is isolated in a protective compartment. Each active substance 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
