La Roche-Posay Hyalu B5 Serum

La Roche-Posay Hyalu B5 is a precision-engineered serum that re-inflates dehydrated, sensitive skin within hours. A dual-weight hyaluronic complex meets 5 % vitamin B5 in a weightless aqueous-gel that vanishes on contact, leaving a breathable, light-reflecting veil.

Clinical instrumentation records a measurable surge in hydration and visible softening of fine lines after a single application; continued use strengthens the barrier and quiets micro-inflammation for a consistently plump, even tone.

The formula is stripped to essentials: pure hyaluronic acid, panthenol, madecassoside and antioxidant thermal spring water—no fragrance, no oil, no comedogenic fillers—making it safe for the most reactive or post-procedure complexion.

Housed in an amber glass dropper that shields actives from light and dispenses exact doses, the serum layers imperceptibly beneath any moisturiser or SPF, delivering prescription-level efficacy with the quiet elegance of daily skincare.
