ACM Duolys Hyal Intensive Anti-ageing Serum has been specially formulated to prevent and visibly correct signs of skin ageing like lines, wrinkles and brown spots. Thanks to a comprehensive combination of potent active substances, this serum combats various signs of ageing and protects against free radicals. The 5% pure vitamin C is combined with hyaluronic acid to neutralize free radicals, intensify collagen production and restore radiance to the complexion. Duolys uses vitamin C as hydrophilic antioxidant, capable of neutralising free radicals (UV, pollution), of stimulating collagen synthesis and of unifying the complexion. 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. Duolys offers accurately targeted and effective solutions for restoring a healthy and youthful skin for as long as possible.
