The Hyalu B5 Pure Hyaluronic Acid Serum can be used in the morning and/or evening on face and neck.

WHAT DOES HYALURONIC ACID SERUM DO FOR SKIN?

Hyaluronic acid serum deeply hydrates the skin, helps protect the lipid barrier, and is suitable for all skin types. It binds water to skin cells, providing valuable moisture and improving skin texture. Learn more about the benefits of hyaluronic acid in skincare.

CAN I APPLY THIS WITH OTHER LA ROCHE-POSAY PRODUCTS?

Then finish with an Anthelios sunscreen for SPF protection. At night, after cleansing, Hyalu B5 Serum can be used alongside retinol products, such as Redermic R Retinol Cream or Retinol B3 Serum.

HOW DO I INCORPORATE A SERUM INTO MY DAILY SKINCARE ROUTINE?
