What Is Aurantiochytrium Sp. Ab811026 Ferment Filtrate?
Aurantiochytrium Sp. Ab811026 Ferment Filtrate is a liquid obtained after growing the marine microorganism Aurantiochytrium strain AB811026 in a nutrient broth then filtering out the solid cells. The remaining filtrate holds water-binding molecules, small peptides, amino acids and natural sugars that the microbe releases during fermentation. These components are known for holding moisture and soothing skin.
Interest in marine ferment ingredients grew in the early 2000s when brands looked for new, sustainable sources of skin-friendly actives. This particular strain was singled out for its high content of polyunsaturated fatty acid fragments and humectant compounds, making it attractive to formulators seeking plant-free alternatives.
Production starts with a lab-grown seed culture that is expanded in large stainless-steel tanks filled with purified water, glucose and minerals. After several days the broth is gently filtered, leaving a clear liquid that is then concentrated and preserved for cosmetic use.
You will most often see Aurantiochytrium Sp. Ab811026 Ferment Filtrate in lightweight serums, sheet masks, gel moisturizers and anti-aging treatments that focus on hydration and skin comfort. It can also appear in soothing after-sun products and eye creams where extra moisture is needed.
Aurantiochytrium Sp. Ab811026 Ferment Filtrate’s Cosmetic Benefits/Uses
This marine ferment pulls in and holds water while helping skin feel smooth and supple.
- Humectant: Draws moisture from the environment into the upper layers of skin, boosting hydration and giving a plump, fresh look.
- Skin Conditioning: Softens rough patches, supports a healthy skin barrier and leaves the surface feeling calm and comfortable.
Who Can Use Aurantiochytrium Sp. Ab811026 Ferment Filtrate
This ferment filtrate is generally well tolerated by all skin types including dry, normal, combination, oily and sensitive. Its lightweight water based nature means it hydrates without leaving a greasy film, so even shine-prone or breakout-prone skin can use it comfortably. Highly reactive or compromised skin usually does fine as it contains no fragrance or known irritants.
The ingredient comes from a lab-cultivated marine microorganism and is not sourced from animals, making it suitable for vegans and vegetarians. Most finished formulas that feature it also avoid animal derived processing aids, but label readers should still confirm a product’s overall vegan status to be sure.
No data suggests problems for women who are pregnant or breastfeeding when this ferment is applied topically. That said this is not medical advice, and anyone who is expecting or nursing should run any skincare products past a doctor just to be safe.
Aurantiochytrium Sp. Ab811026 Ferment Filtrate does not make skin more sensitive to the sun, so it is fine for daytime wear. Of course daily sunscreen is still encouraged for general skin health.

Comedogenic Rating
Rating: 0 out of 5
Aurantiochytrium Sp. Ab811026 Ferment Filtrate is water based and contains no heavy oils or waxes that might clog pores. Its small peptides, sugars and humectant molecules sit on the surface to pull in moisture rather than forming an occlusive film. For these reasons it earns a solid 0 on the comedogenic scale.
Suitable for acne prone or breakout prone skin.
As with any ferment, the final product must be properly preserved so bacteria or yeast do not grow and cause secondary breakouts.
Summary
Aurantiochytrium Sp. Ab811026 Ferment Filtrate acts mainly as a humectant and skin conditioning agent. The marine microbe releases amino acids, natural sugars and fatty acid fragments during fermentation, all of which bind water to keep skin plump, soft and comfortable.
It is still a niche ingredient, showing up in select hydrating serums, masks and soothing treatments rather than crowding shelves like hyaluronic acid or glycerin. Formulators who want a plant free yet sustainable hydrator appreciate its unique story and lightweight feel.
Topical use is considered very safe with low risk of irritation or pore clogging. As with any new skincare step it is smart to patch test first to be sure your skin agrees with it.
