What Is Pseudoalteromonas Ferment Lysate Extract Filtrate?
Pseudoalteromonas Ferment Lysate Extract Filtrate comes from a marine bacterium called Pseudoalteromonas. The bacterium is first grown in a controlled fermentation tank filled with nutrient-rich seawater. After it multiplies, the cells are gently broken open, or lysed, to release their inner proteins, amino acids and sugars. The liquid that remains is then filtered to remove cell debris, leaving a clear filtrate packed with skin-loving molecules.
This microorganism was first studied by oceanographers who noticed it produced protective compounds that helped it survive in harsh, cold seas. When skin researchers tested those compounds in the lab, they found they could comfort dry skin and soften signs of aging. By the early 2000s the filtrate began appearing in premium anti-aging creams, and it has since moved into a wide range of daily skin care products.
You will most often see Pseudoalteromonas Ferment Lysate Extract Filtrate in leave-on formulas where its hydrating and smoothing qualities have time to work, such as serums, sheet masks, moisturizers, eye creams, after-sun gels and intensive overnight treatments. It is also blended into some lightweight lotions meant for oily skin because it conditions without a heavy or greasy feel.
Pseudoalteromonas Ferment Lysate Extract Filtrate’s Cosmetic Benefits/Uses
This ingredient is prized for one main role in skin care products.
Skin conditioning: The filtrate supplies peptides and sugars that help draw water to the skin, support the natural moisture barrier and improve softness. With regular use it can leave skin feeling smoother and looking more resilient while minimizing the appearance of fine lines caused by dryness.
Who Can Use Pseudoalteromonas Ferment Lysate Extract Filtrate
This marine ferment suits nearly every skin type, from dry and mature to balanced, combination or oily. Its lightweight texture and ability to boost moisture without leaving residue make it friendly even for breakout-prone skin. People with very sensitive or easily irritated skin usually tolerate it well because it is gentle and free of fragrance and harsh solvents.
The ingredient is produced through bacterial fermentation, not derived from animals, so it is considered suitable for vegan and vegetarian lifestyles.
No data point to problems for women who are pregnant or breastfeeding when the ferment is used topically at cosmetic levels. Still this is not medical advice and anyone who is expecting or nursing should have a quick chat with a healthcare professional before adding new products to a routine.
Pseudoalteromonas Ferment Lysate Extract Filtrate does not increase photosensitivity, so it will not make skin more prone to sunburn. Standard daytime sun protection is still important for overall skin health.
Potential Side Effects/Adverse Reactions
Responses to topical Pseudoalteromonas Ferment Lysate Extract Filtrate vary from person to person. The effects listed below are merely potential outcomes and they are unlikely for most users when the ingredient is formulated and used correctly.
- Mild redness or warmth shortly after application

If you experience any of the reactions above discontinue use and consult a healthcare professional for guidance.
Comedogenic Rating
Rating: 0 (non-comedogenic)
Pseudoalteromonas Ferment Lysate Extract Filtrate is water based and contains almost no oils or waxes that could block pores. The peptides and sugars it delivers dissolve easily and rinse away without leaving a film. Because it does not add extra sebum-like material to the skin it earns the lowest possible score on the pore-clogging scale.
With this rating the ferment is generally considered safe for acne-prone or breakout-prone skin. As always the full product formula and how often it is applied will also influence real-world results.
If used in a very rich cream that is already heavy with butters or silicones the overall product could still clog pores. Check the entire ingredient list if congestion is a concern.
Summary
Pseudoalteromonas Ferment Lysate Extract Filtrate is a marine ferment that conditions skin by delivering moisture-binding peptides and sugars that support a healthy barrier and leave the surface smoother and suppler. It is showing up more often in modern serums masks and creams thanks to its gentle yet noticeable softening effect and the growing interest in ocean-derived actives.
Safety data and real-world use both point to a low risk of irritation for most people including those with sensitive or acne-prone skin. Still everyone’s skin is unique so it is smart to patch test any new product that contains this ingredient before adding it to your daily routine.
