How can I maximize the benefit of Hylau B5?
For the deepest hydration, apply Hyaluronic Acid to damp sink to maximize absorption. We recommend that you mist your skin with our Thermal Spring water before use. Dont forget to lock in moisture with a moisturizer.
Why is Hyaluronic Acid effective for anti aging?
This skincare ingredient can hold up to 1000x its weight in water, which is important considering as we age our skin loses the ability to hold onto water and stay moisturized—causing visible loss of plumpness and suppleness in our skin’s appearance.
What are the main benefits of La Roche-Posay Hyalu B5 Serum?
It hydrates, plumps, and repairs skin to visibly reduce fine lines and wrinkles. The lightweight formula leaves skin feeling soft, firm, and revitalized.
What are the key active ingredients in this anti-aging face serum?
Formulated with two types of pure hyaluronic acid for multi-depth plumping, vitamin B5 (panthenol) to repair skin barrier, and madecassoside.
How do I apply La Roche-Posay Hyalu B5 Serum in my skincare routine?
Apply 3 to 4 drops morning and evening onto a cleansed face and neck before applying your moisturizer. Follow with SPF during the daytime.
