Discover the benefits of Hyaluronic Acid

The key to hydrated skin

Always with your well-being in mind, we wanted to share with you another La Roche Posay clinically proven dermatological ingredient, Hyaluronic Acid. Learn more about this critical substance that you will likely want to add to your skincare regime, if you have not already done so.


Hyaluronic Acid is a naturally occurring molecule found in the skin, connective tissue and eyes. It acts as a magnet for moisture so your skin remains hydrated and healthy throughout the day.

However, our skin’s ability to produce Hyaluronic Acid declines with age, which leads to dryness, fine lines, wrinkles and less elasticity. Hence the reason why a boost of this ingredient becomes so important over time; some of our products a high concentration in Hyaluronic Acid in order to help you replump your skin.


  • It penetrates deeply and binds water to skin cells to boost elasticity and activate skin hydration and renewal
  • It reduces the visibility of fine lines and wrinkles by retaining moisture
  • It has antioxidant properties acting as a shield against toxins such as environmental pollution and UV rays


Hyaluronic Acid is a safe moisture-binding substance which provides gentle hydration.

Hyaluronic Acid is also a humectant, which means it draws moisture from air. Only one gram of Hyaluronic Acid can hold up to six liters of water. It therefore has the ability to help boost hydration for all skin types, and is especially beneficial for dry & dehydrated skin.


Does topical Hyaluronic Acid work? The short answer is yes! However, it's up to you how you decide to use Hyaluronic Acid in your daily beauty routine. A skin serum, for example, can be a simple new step to introduce without sacrificing your other skincare products, and can be applied at both morning and/or night-time depending on your preference.

The Hyalu B5 Hyaluronic Acid Serum by La Roche-Posay works to restore your skin cells with moisture, which gives plumper-looking skin that is more able to retain water by itself. Hydrated skin in turn leads to a more radiant, glowing complexion and reduced signs of aging.
How to apply Hyaluronic Acid? Use your fingertips to gently apply the serum to the skin using small circular motions to help the serum fully absorb into the epidermis.

Another option is adding Hyalu B5 Care Hyaluronic Acid Cream by La Roche-Posay to your skin regimen; not only does it provide a deep, lasting hydration and skin barrier repairs, but it also combines the power of Vitamin B5 for a plumping effect that targets wrinkles, loss of volume and elasticity. This hydrating cream can be applied both morning and evening on face and neck for a skin that feels regenerated and bouncy.

Now that you know what Hyaluronic Acid does for skin, don’t miss out on all the possible benefits from including the right products in your skincare routine. With the help of this mighty skincare ingredient, you can help keep those early signs of skin aging at bay!
