Hyaluronic acid has gained immense popularity in the skincare industry due to its remarkable ability to hold water, making it a potent hydrating agent. This moisture-retaining quality not only helps skin maintain optimal hydration levels but also imparts a plumping effect, reducing the appearance of fine lines and wrinkles.

Hyaluronic acid is one of the key ingredients in La Roche Posay Hyalu B5 Serum. While hyaluronic acid is a beneficial ingredient, it’s crucial to remember that the overall formulation and combination of ingredients are equally important for its effectiveness and performance on your skin.
That’s why below we’re going to discuss the overall product formulation and give you all the details on the key ingredients in La Roche Posay Hyalu B5 Serum. We’ll also share some La Roche Posay reviews so that you can get an idea of what customers really think of this product.

What Are The Key Ingredients in La Roche Posay Hyalu B5 Serum?
Just as the name suggests, hyaluronic acid is one of the key ingredients in La Roche Posay Hyalu B5 Serum. Before we give you the details on how hyaluronic acid may benefit your skin, we have to point out that this product contains a very high concentration of denatured alcohol.
Denatured alcohol is the third highest concentration ingredient in La Roche Posay Hyalu B5 Serum. So why is this a problem? Let’s take a closer look at what high amounts of denatured alcohol will do to your skin.
Using this type of alcohol in skincare products makes it seem like the product is benefitting your skin. That’s because, initially, alcohol gives products a quick-drying finish, immediately degreases the skin, and imparts a weightless feel.
However, the major problem with using high concentrations of denatured alcohol is that this ingredient is well known to cause skin dryness, irritation, and even disruption of the skin barrier.
Furthermore, alcohol can disrupt the lipids that make up the stratum corneum (the outermost layer of skin), according to a publication in the journal BBA Biomembranes.
While alcohol may provide short term benefits, it’s not doing your skin any good in the long run. We will still discuss the key ingredients in La Roche Posay Hyalu B5 Serum, but keep in mind that the benefits may not outweigh the risks of using a serum with such a high concentration of denatured alcohol.
La Roche Posay Hyalu B5 Serum contains sodium hyaluronate, the salt form of hyaluronic acid.
Sodium hyaluronate and hyaluronic acid are basically the same and the two names are used interchangeably in the skin care industry. The main differences are that sodium hyaluronate is more stable, easier to formulate, and cheaper. That’s why it is common to see sodium hyaluronate on an ingredient list even though the product name might say hyaluronic acid.
Once applied to the skin, sodium hyaluronate provides the same benefits of hyaluronic acid. Those benefits include improved skin hydration, as well as a more plump complexion with fewer lines and wrinkles.
The “B5” in the name of this serum comes from the inclusion of panthenol, also known as provitamin B5.
Clinical studies show that panthenol-based formulations increase skin moisture content and had a significant effect on skin barrier function by decreasing transepidermal water loss (TEWL).
Furthermore, panthenol has been shown to improve the skin barrier function. It’s able to penetrate into the deeper skin layers and is absorbed into the cells before being metabolized into pantothenic acid. This ability to penetrate deeply is useful in adding essential moisture, helping to maintain skin’s natural moisture balance.
