Hyaluronic Acid (Dual Molecular Weight)
A dual-molecular weight complex that targets both the skin surface and deeper dermal layers simultaneously. High molecular weight HA forms a moisture-locking film on the surface, while low molecular weight HA penetrates deeply to plump and restore volume from within.
Vitamin B5 (Panthenol)
A skin-soothing provitamin that accelerates the skin barrier repair process, reduces inflammation, and enhances the skin's ability to retain moisture. Works synergistically with Hyaluronic Acid to amplify hydration results.
Madecassoside
A purified extract of Centella Asiatica renowned for its calming and barrier-fortifying properties. Reduces skin sensitivity, supports cellular repair, and helps restore the skin's natural equilibrium.
Everyday hydration for skin that feels thirsty
La Roche Posay Hyalu B5 Hyaluronic Acid Serum brings a fresh, lightweight feel to your daily routine. Hyaluronic acid helps skin hold onto moisture for a smoother, plumper look, while vitamin B5 helps keep skin feeling comfortable. The serum absorbs quickly and layers easily beneath your moisturiser.
A simple moment of care
After cleansing, press a few drops into your face and neck. Enjoy the soft, hydrated feel before finishing with moisturiser, morning or evening.
