ACM Duolys Hyal Intensive Anti-Ageing Serum has been specially formulated to prevent and visibly correct signs of skin ageing such as lines, wrinkles and brown spots. Thanks to a comprehensive combination of potent active substances, this serum combats multiple signs of ageing and protects against free radicals. The pure vitamin C combined with hyaluronic acid neutralizes free radicals, stimulates collagen production and restores radiance to the complexion. Duolys uses vitamin C as a hydrophilic antioxidant capable of neutralising free radicals caused by UV exposure and pollution, stimulating collagen synthesis and unifying the complexion. Combined with vitamin E and hyaluronic acid, the formula moisturises, reinforces collagen production and revives skin radiance. Vitamin C is isolated in a protective compartment to preserve stability and efficacy, delivering targeted anti-ageing action on the face, neck and décolleté while remaining gentle on fragile skin.
