For years, hyaluronic acid has been one of the best-known ingredients in hydrating skincare. But another ingredient is attracting more attention from skincare formulators: Pentavitin®, also known as Saccharide Isomerate.
Pentavitin is interesting because it does more than provide a quick moisture boost. It helps the skin retain hydration for longer and supports the natural skin barrier.
So, is Pentavitin better than hyaluronic acid?
Not necessarily. They work differently — and that is exactly why they can complement each other so well.
Pentavitin® is a hydrating ingredient based on Saccharide Isomerate.
It has a strong affinity for keratin in the stratum corneum, the outermost layer of the skin. This allows it to remain associated with the skin and continue supporting hydration even after rinsing.
According to ingredient manufacturer dsm-firmenich, Pentavitin can provide hydration benefits for up to 72 hours, depending on the formulation.
This makes it especially interesting for dry or dehydrated skin, tightness after cleansing and skin with a weakened moisture barrier.
Both ingredients help hydrate the skin, but they work in different ways.
Hyaluronic acid is a humectant. It attracts and holds water, helping the skin feel more hydrated and appear plumper.
Pentavitin binds to the outer layers of the skin and helps support longer-lasting moisture retention.
In simple terms, hyaluronic acid is excellent at attracting water, while Pentavitin is particularly interesting for helping the skin hold on to hydration for longer.
You do not necessarily need to choose between them. Modern skincare formulas increasingly combine different hydration mechanisms to provide both immediate and longer-lasting moisture support.
Seeing “hyaluronic acid” on an ingredient list does not automatically mean a product will hydrate the skin effectively.
Its performance depends on molecular weight, concentration, the complete formula and the condition of the skin barrier.
That is why good skincare formulation is moving away from relying on one hero ingredient.
Healthy skin does not only need water. It also needs to be able to retain that water.
This is where Pentavitin becomes especially interesting.
When the skin barrier is compromised, water escapes more easily from the skin. This process is known as transepidermal water loss, or TEWL.
The result can be dryness, tightness, roughness and discomfort.
Research into Saccharide Isomerate suggests that formulas containing this ingredient can help improve hydration and support skin-barrier recovery.
More recent clinical research has also studied Saccharide Isomerate-containing formulas after aesthetic treatments such as IPL and fractional CO₂ laser, with encouraging results for hydration and barrier recovery.
These studies looked at complete formulas rather than Saccharide Isomerate alone, but they help explain why the ingredient is becoming increasingly relevant in barrier-focused skincare.
There is no simple winner.
Hyaluronic acid is excellent at attracting and holding water. Pentavitin is particularly interesting for longer-lasting moisture retention and skin-barrier support.
A good way to think about it is:
Hyaluronic acid helps bring hydration to the skin. Pentavitin helps the skin hold on to it.
And that makes Pentavitin especially interesting in one category you may not immediately expect: cleansers.
Cleansing is essential, but some cleansers can leave the skin feeling tight or stripped afterwards.
A modern cleanser should therefore do more than remove sebum, sunscreen and impurities. It should cleanse effectively without unnecessarily compromising skin comfort.
Because Pentavitin binds to the outer layers of the skin and is not easily rinsed away, it is particularly interesting in rinse-off formulas.
Hydration does not always have to start with your serum or moisturiser.
It can begin during cleansing.
This is why Pentavitin® is included in Dr. Medion Spaoxy Foaming Wash.
The formula combines cleansing with ingredients selected to support hydration and skin comfort, including Pentavitin, ceramides, Tremella Fuciformis Polysaccharide, glycerin and propanediol.
Together, these ingredients help cleanse the skin while reducing the uncomfortable tight feeling that can follow washing.
The idea is simple:
Clean skin, without the stripped feeling afterwards.
So, will Pentavitin replace hyaluronic acid?
Probably not.
But it represents an important shift in skincare: from simply adding hydration to helping the skin retain hydration for longer.
