Collagen, Elastin, CoQ10, Hyaluronic Acid, and Vitamins A through K in a concentrated serum that rebuilds skin's structural foundation while protecting it from further damage. Hydrolyzed Collagen and Elastin are small enough to actually penetrate — not just coat the surface.

The Bio Jouvance Paris edge: Most collagen serums use high molecular weight proteins that sit on the surface. Bio Jouvance Paris uses hydrolyzed forms small enough to penetrate where structural support matters. CoQ10 powers cellular repair, Hyaluronic Acid plumps from within, and a full vitamin spectrum provides comprehensive antioxidant defense. Layer under Colastin Age-Defying Cream for the complete protocol. For mature and sun-damaged skin. The serum that gives your skin back what aging takes away.

Hero Ingredients and Their Benefits:

• Hydrolyzed Collagen and Elastin: Low molecular weight structural proteins that actually absorb into skin, rebuilding the firmness and resilience that aging depletes.
• CoQ10: Powers the cellular energy production that drives repair, renewal, and defense processes — the fuel your skin cells need to function at their best.
• Hyaluronic Acid and Vitamins A through K: Deep plumping hydration and comprehensive nutritional support for visible firming and radiance.

How to Use:

Thoroughly cleanse and tone the skin. Apply 15 to 20 drops of Colastin Age-Defying Serum on the face, neck and decollete area. Gently massage using upward, outward strokes until fully absorbed. Follow with the appropriate Bio Jouvance Paris moisturizer. Daytime: finish with 4 in 1 Sunscreen SPF 50 for UV protection.

Complete Your Treatment:

Pair with the Colastin Age-Defying Cream to lock in the serum's structural proteins for the complete Colastin protocol that rebuilds firmness and resilience.
