What Is Marinobacter Shengliensis/Cabbage Stem Ferment Extract Filtrate?
Marinobacter Shengliensis/Cabbage Stem Ferment Extract Filtrate starts its life as the leftover stems of common cabbage. Instead of being discarded these stems are mixed with the friendly sea-living bacterium Marinobacter shengliensis and left to ferment. During this natural process the microbe breaks down plant matter into smaller skin-loving pieces such as amino acids, peptides and minerals, then the mixture is carefully filtered to remove solids. The result is a clear liquid rich in nutrients that skin can recognize and use.
The idea of using fermented plants in beauty products took off in the past decade as brands looked for gentler active ingredients and ways to reuse food waste. This specific filtrate gained attention because cabbages are packed with vitamins while Marinobacter shengliensis is known for thriving in harsh saltwater, a trait that hints at a strong protective ability. Together they create a mild yet effective ingredient that conditions skin without heaviness.
After production the filtrate is blended into water-based formulas. You will most often see it in hydrating serums, sheet masks, soothing gels, daily moisturizers and anti-aging creams where it helps give a smoother feel and a fresh finish.
Marinobacter Shengliensis/Cabbage Stem Ferment Extract Filtrate’s Cosmetic Benefits/Uses
This ferment filtrate is valued for one main purpose in skincare.
Skin conditioning: The mix of natural humectants, amino acids and minerals helps skin hold on to water, leaves the surface soft and supple and supports a healthy looking barrier. Products that include it can feel more cushioning on application and may help reduce the look of rough or flaky patches over time.
Who Can Use Marinobacter Shengliensis/Cabbage Stem Ferment Extract Filtrate
This ferment filtrate is lightweight and water based which makes it a friendly choice for dry, normal, combination and oily skin. Its hydrating nature can calm dry patches while the lack of heavy oils keeps it from feeling greasy on oilier areas. It does not have known irritants so even sensitive skin usually gets along with it, though very reactive skin should still watch how it feels.
The ingredient is sourced from cabbage stems and a marine microorganism grown in a lab. No animal parts are used at any point so it fits vegan and vegetarian standards.
Current data shows no specific risks for pregnant or breastfeeding women when the ingredient is applied to skin. Still this is not medical advice. Anyone expecting or nursing should run the full product list by a qualified health professional to be on the safe side.
Marinobacter Shengliensis/Cabbage Stem Ferment Extract Filtrate does not make skin more sensitive to sunlight so you do not need extra sun-protection steps beyond a normal daily SPF.

Comedogenic Rating
Rating: 0 / 5
This ferment filtrate is water based, contains no pore clogging oils or waxes and has a very small molecular size thanks to the fermentation process. Those factors make it unlikely to sit in pores or trap dead cells, giving it a true non-comedogenic profile. It should be suitable for people prone to acne or breakouts.
Because the ingredient is usually added at modest levels in lightweight formulas the risk of buildup that can lead to congestion is minimal.
Summary
Marinobacter Shengliensis/Cabbage Stem Ferment Extract Filtrate mainly conditions skin by supplying naturally derived humectants, amino acids and trace minerals that draw in water and support a smooth barrier. Fermentation breaks the cabbage stems into smaller parts the skin can easily use while the marine bacterium contributes protective factors.
The ingredient is still a niche pick so it is not found in every aisle yet, but its links to upcycled plant waste and gentle hydration are helping it gain quiet popularity among eco-minded brands.
Overall safety data is favorable with low irritation and zero comedogenic risk, making it a low stress addition to most routines. As with any new product a quick patch test is a smart step to rule out personal sensitivities.
