Universal hydrating booster serum
Le Sérum Hyaluronique (The Hyaluronic Serum) is a unique combination of hyaluronic acid, organic silica + L-rhamnose, and a biomimetic peptide in a minimalist formula triggering 3 actions. It strengthens the skin barrier and promotes hydration thanks to a combination of 2 different molecular weights of hyaluronic acid. It also stimulates the synthesis of collagen fibers and firmness proteins through the synergistic action of organic silica and L-rhamnose. Finally, it protects hyaluronic acid and the firmness proteins already present in the skin via a specific biomimetic peptide that prevents its degradation.
Size: 30ml

FAQ
How do I use The Hyaluronic Serum?
Apply a few drops to clean skin, morning and/or evening, before your moisturiser. As a hydrating booster it layers under richer creams and works well as a base for daytime SPF. Gently press into the face and neck. Because the formula is minimalist, you can use it daily as part of an existing routine.
Who is this serum for?
It is a universal hydrating booster suitable for most skin types looking to strengthen the skin barrier and improve hydration. It is a good choice if your skin feels tight, dehydrated or lacks bounce. With 1.4% hyaluronic acid across two molecular weights, it supports skin needing surface and deeper hydration.
What are the key ingredients?
The formula combines hyaluronic acid at two different molecular weights for multi-level hydration, organic silica plus L-rhamnose to stimulate collagen and firmness proteins, and a biomimetic peptide that helps protect the hyaluronic acid and firmness proteins already present in your skin from degradation.
How does it fit with other products?
Apply it after cleansing and any water-based treatments, then follow with your moisturiser to seal in hydration. It layers well under sunscreen and makeup. Because it is a focused, minimalist booster, it pairs easily with the rest of your routine rather than replacing your existing serums or creams.
When can I expect to see results?
Many people notice skin feels more hydrated, plumper and comfortable shortly after applying, as hyaluronic acid draws in moisture. Improvements in firmness and skin barrier strength build gradually with consistent daily use over several weeks. Results vary between individuals, so use it regularly for the best outcome.
