Serum Repair: The Original Hyaluronic Acid Power Serum

The First of Its Kind – A Skincare Pioneer Since 2005 

In 2005, Dr Jean-Louis Sebagh launched Serum Repair, becoming one of the very first to introduce hyaluronic acid in a professional-grade skincare formula. Nearly two decades later, it remains his global best-seller, a testament to its unrivalled efficacy and cult following.

But this is no ordinary HA serum. Serum Repair goes beyond hydration, delivering clinically backed actives that visibly transform skin’s structure, smoothness, and glow.

Why Serum Repair Is More Than Just a Hyaluronic Acid

At its core, Serum Repair is a lightweight, water-gel concentrate designed to deliver an instant “plumped-from-within” effect. But unlike basic hydrating serums, it features a synergistic blend of micro-molecular hyaluronic acid, marine-derived collagen peptides, and a powerful collagen-signalling peptide (Palmitoyl Pentapeptide-4).

Together, these advanced ingredients do more than hydrate, they stimulate regeneration, restore elasticity, and rebuild skin’s internal support network.

The Peptide Advantage: Why Skin Loves Them 

Peptides are among the most effective anti-ageing ingredients in dermatological science. In Serum Repair, Palmitoyl Pentapeptide-4 plays a key role in:

• Stimulating collagen and elastin synthesis
• Strengthening the extracellular matrix
• Improving barrier function
• Enhancing skin repair when used with antioxidants or growth factors

This is why users experience not only improved hydration but firmer, denser, more youthful skin over time.

Key Benefits of Serum Repair

• Deep Hydration & Instant Plump

Formulated with micro-molecular hyaluronic acid, this lightweight serum draws moisture deep into the skin for a visibly plumper, smoother, and more radiant complexion.

• Fine Line Softening & Collagen Support

A potent combination of Palmitoyl Pentapeptide-4 and hydrolysed marine collagen helps reduce the appearance of fine lines and encourages natural collagen renewal for firmer, more elastic skin.

• Barrier Fortification

Glycerine and collagen peptides strengthen the skin’s natural barrier, reducing moisture loss, calming sensitivity, and enhancing resilience to environmental stress.

• Universally Compatible

Oil-free, fragrance-free, and non-comedogenic, Serum Repair is suitable for all skin types, including sensitive. It layers effortlessly with other products and doubles as a soothing serum post-shave or post-procedure.

Inside the Formula: The Science of Structural Repair

Palmitoyl Pentapeptide-4

A five-amino-acid ‘messenger’ peptide that instructs fibroblasts to increase production of collagen types I and III, elastin, and glycosaminoglycans, visibly firming skin over 4–8 weeks.

Micro-Molecular Hydrolysed Collagen 

Low-molecular-weight collagen fragments that act both as building blocks and bio-signals to stimulate fresh collagen synthesis — restoring bounce, smoothing texture, and supporting skin healing.

Sodium Hyaluronate

The salt form of HA that penetrates quickly to instantly plump, hydrate, and deliver peptides deeper into the skin.

Together, these actives help reboot skin’s collagen network, improving tone, elasticity, and long-term skin quality — making Serum Repair effective for both fine lines and advanced laxity.
