The La Roche-Posay Hyalu B5 Serum targets tight, flat skin. Your skin needs hydration at two depths, not just surface moisture. Dual hyaluronic acid fills deep and smooths your texture fast. You get visibly plumper, softer skin from the first use.

Key Benefits

  • Dual Hyaluronic Acid: The La Roche-Posay Hyalu B5 Serum fills and smooths at two skin depths from the first use.
  • Vitamin B5 Comfort: Panthenol soothes and moisturizes your skin throughout the day.
  • Madecassoside Calm: This Centella Asiatica derivative nourishes sensitive and stressed skin.
  • Moisture Barrier Support: Dimethicone seals hydration in and cuts moisture loss hour after hour.
  • Selenium-Rich Thermal Water: La Roche-Posay's spring water base calms and strengthens your skin.
  • Fragrance-Free Formula: Allergy-tested and safe for twice-daily use on all skin types.

Key Ingredients

La Roche-Posay Thermal Spring Water: Selenium-rich water sourced in La Roche-Posay, France. It calms reactive skin and forms the base of the formula. Sodium Hyaluronate: A form of hyaluronic acid absorbed in the upper skin layers. It plumps and smooths your surface texture. Hydrolyzed Hyaluronic Acid: A smaller molecule that reaches deeper into the skin. It fills from within for longer-lasting volume. Panthenol (Vitamin B5): Soothes and moisturizes your skin barrier all day. Madecassoside: A Centella Asiatica-derived ingredient that nourishes and calms sensitive or irritated skin.
