Pseudoalteromonas Exopolysaccharide: the hydrating marine active that plumps the skin like hyaluronic acid

Why marine actives are revolutionizing hydrating skincare

In the landscape of advanced cosmetics, actives derived from marine bio-fermentation are playing an increasingly central role in hydrating and anti-aging formulations.

Among these, Pseudoalteromonas Exopolysaccharide is one of the most interesting ingredients for its ability to provide intense, deep, and long-lasting hydration, contributing to the improvement of skin texture and the visible reduction of dehydration signs.

Thanks to its marine biotechnological origin, this polysaccharide is often considered a valid natural alternative to hyaluronic acid.

What is Pseudoalteromonas Exopolysaccharide

Pseudoalteromonas Exopolysaccharide is a polysaccharide obtained through the bio-fermentation of a marine bacterium of the genus Pseudoalteromonas.

It is a high-molecular-weight molecule belonging to the exopolysaccharide family, natural substances produced by marine microorganisms for protection and adaptation to the environment.

In cosmetics, it is used for its ability to interact with water and the skin surface, creating a hydrating and protective film.

How it works on the skin

Deep and long-lasting hydration

The main mechanism of action of Pseudoalteromonas Exopolysaccharide is its extraordinary ability to retain water.

Once applied to the skin, it:

helps maintain hydration in the superficial layers;

reduces transepidermal water loss;

improves skin softness;

provides an immediate effect of "fuller" and smoother skin.

This makes it particularly useful in treatments for dry or dehydrated skin.

Hydrating filler effect and wrinkle reduction

Thanks to its ability to create a uniform hydrating film, this active visibly helps improve the appearance of fine lines related to dehydration.

The plumping action is often compared to that of hyaluronic acid, with which it shares the ability to improve skin volume and smoothness by attracting and retaining water.

The result is skin that is:

smoother;

more elastic;

firmer;

plumper.

Support for the skin barrier

In addition to its hydrating effect, Pseudoalteromonas Exopolysaccharide helps strengthen the skin's barrier function.

The polysaccharide film formed on the skin surface helps to:

protect against external agents;

maintain hydro-lipid balance;

reduce feelings of dryness and discomfort.

Why it is considered an alternative to hyaluronic acid

One of the most interesting features of this active is its functional similarity to hyaluronic acid.

Both compounds:

retain large amounts of water;

improve skin hydration;

contribute to a plumping effect;

help reduce the visibility of fine lines.

Pseudoalteromonas Exopolysaccharide, however, stands out for its marine and biotechnological origin, which makes it particularly valued in new-generation skincare formulations.

Hydration and anti-aging effect

Smoother and more radiant skin

Adequate hydration is one of the key factors in maintaining youthful skin.

This active helps improve:

facial radiance;

uniformity of skin texture;

surface elasticity.

Reduction of dehydration signs

Fine lines caused by water loss in the skin tend to visibly diminish with regular use of highly effective hydrating ingredients like this polysaccharide.

More elastic and comfortable skin

By improving the level of hydration, the skin appears more elastic, soft, and resistant to external aggressions.

In which skincare products it is found

Pseudoalteromonas Exopolysaccharide is primarily used in:

hydrating serums;

plumping creams;

face masks;

anti-aging treatments;

skincare for dehydrated or sensitive skin.

It is often combined with hyaluronic acid, glycerin, and other humectant actives to enhance its hydrating effect.

Who it is suitable for

This active is particularly suitable for those with:

dry or dehydrated skin;

loss of surface elasticity;

dehydration fine lines;

dull or stressed skin;

need for an immediate plumping effect.

Conclusion

Pseudoalteromonas Exopolysaccharide represents one of the most interesting marine actives in modern hydrating cosmetics.

Thanks to its ability to retain water and improve the skin barrier, it helps make the skin smoother, more elastic, and visibly plumper.

Its marine biotechnological origin and its effectiveness make it a valid alternative to hyaluronic acid in new-generation skincare formulations.
