Sérum N°28

Apply a few drops to cleansed face and neck, massaging gently until fully absorbed. Can also be applied to the eye and lip contour areas. Follow with the recommended Mansard cream. Use morning and/or evening.

• Hydrolyzed Collagen: A bioavailable complex of collagen-derived amino acids and short peptide fragments. Supports fibroblast activity to stimulate the skin's own collagen production, restore volume and firmness, and visibly smooth wrinkles by improving skin density and elasticity.

How is this different from Sérum N°27 Elastine Fondamentale?

Both target structural aging, but through different proteins. Sérum N°28 Collagène Vital focuses on collagen — responsible for skin density, volume, and firmness. Sérum N°27 Elastine Fondamentale focuses on elastin — responsible for the skin's ability to stretch and return to shape. They can be used together or alternated for comprehensive structural support.

Can topical collagen actually penetrate the skin?

Hydrolyzed collagen is broken down into smaller amino acid fragments and short peptides, which are small enough to interact with the skin and support fibroblast activity — the cells responsible for producing collagen. While the mechanism differs from endogenous collagen production, clinical evidence supports the visible efficacy of hydrolyzed collagen in improving firmness and reducing wrinkle depth.

Which cream pairs best with this serum?

Crème Top Fermeté Anti-Rides is the most aligned pairing for a firming and anti-wrinkle protocol. Crème Régénératrice N°2 is an excellent choice for dry or mature skin requiring additional nourishment.

At what age should I start using it?

Collagen production begins declining from the mid-20s. This serum is suitable from that point onward, with the greatest visible results in skin from the mid-30s and beyond where laxity and wrinkle formation are more established.
