What is hyaluronic acid?

A common ingredient in many anti-aging skincare products, hyaluronic acid (aka "HA") nevertheless remains a mystery to many. We take a closer look at hyaluronic acid, and how you can get the best anti-aging results by incorporating it into your daily routine.

Hyaluronic acid: your ally against cutaneous aging

Hyaluronic acid is a naturally-occurring molecule produced by the body and can also be re-created in laboratories. When it comes to cutaneous aging, hyaluronic acid has a "unique capacity in retaining water". This water retention is essential for keeping skin cells healthy and functioning at optimum levels.

Without enough hydration, our skin cells weaken, which leads to the tell-tale signs of aging, such as fine lines, wrinkles, dullness and lack of elasticity. Research tells us that "the hydration of the skin critically depends on the HA-bound water in the dermis and in the vital area of the epidermis"

Because our natural levels of hyaluronic acid production start to decrease in our mid-twenties, it's recommended to top up the skin using skincare products infused with hyaluronic acid. This prevents the onset of premature cutaneous aging.

La Roche-Posay would recommend...

It's up to you how you decide to use hyaluronic acid in your daily beauty routine. A 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. Use your fingertips to gently apply the serum to the skin using small circular motions to help the serum fully absorb into the epidermis.

With the help of hyaluronic acid, you can help keep those early signs of skin aging at bay!
