Discover intense hydration with L’Oréal Paris Hyaluron Expert 1.5% Hyaluronic Acid Serum — a powerful replumping face serum clinically proven to reduce fine lines by up to -60% in 4 weeks.

Formulated with 1.5% pure Hyaluronic Acid, including patented Micro-Hyaluron that is 50x smaller* for deeper penetration, this lightweight hydrating serum delivers immediate moisture and long-lasting plumping action. Hyaluronic Acid is known to retain up to 1000x its weight in water, helping to restore skin’s hydration balance and visibly smooth dehydration lines.

The fast-absorbing, non-sticky texture deeply hydrates without clogging pores, leaving skin looking fresher, smoother and more youthful. Dermatologist-validated and suitable for all skin types, including sensitive skin.

In just one use, skin feels intensely hydrated. With continued use, fine lines appear visibly reduced, skin looks plumper and elasticity feels improved.
