What Is Cordyceps Militaris/Germinated Soybean Ferment Extract Filtrate?
Cordyceps Militaris/Germinated Soybean Ferment Extract Filtrate comes from a mix of two natural sources: germinated soybeans and the mushroom Cordyceps militaris. The soybeans are first sprouted to boost their nutrient content then they are fermented with the fungus. During fermentation enzymes break down proteins sugars and lipids into smaller compounds such as peptides amino acids and antioxidant molecules. After fermentation the liquid portion is separated filtered and refined to create the clear to light-amber filtrate used in skincare.
Fermented ingredients have long been prized in East Asian beauty traditions for their skin loving properties. As research grew on both soy and Cordyceps scientists began blending them to tap into their combined soothing and protective effects. The result found its way into modern cosmetic labs in the early 2000s where formulators valued its mildness and bioactive profile.
The filtrate is produced in controlled tanks that keep temperature moisture and oxygen at just the right levels for the fungus to thrive. Once fermentation is complete the mixture is pressed filtered and sometimes lightly preserved to ensure stability on the shelf.
You will often spot Cordyceps Militaris/Germinated Soybean Ferment Extract Filtrate in hydrating sheet masks anti-aging serums lightweight moisturizers calming lotions and restorative night creams. It is also added to after-sun gels and barrier-support essences where extra soothing care is needed.
Cordyceps Militaris/Germinated Soybean Ferment Extract Filtrate’s Cosmetic Benefits/Uses
This dual-fermented filtrate brings more than one perk to a skincare formula
- Skin Conditioning: Helps skin feel softer and look smoother thanks to its mix of peptides sugars and amino acids that boost surface hydration and support a healthy glow
- Skin Protecting: Supplies antioxidants that shield the skin from everyday environmental stress like pollution and light exposure helping to maintain an even toned appearance
Who Can Use Cordyceps Militaris/Germinated Soybean Ferment Extract Filtrate
This ferment filtrate is generally well tolerated by all major skin types—dry, normal, combination, oily and even sensitive—thanks to its gentle, water-based composition. It hydrates without adding heaviness so acne-prone or oily skin can benefit just as much as a drier complexion. There are no known properties that make it unsuitable for any specific skin type, though people with a documented allergy to soy should avoid it because trace soy proteins may remain after filtration.
The ingredient is produced from germinated soybeans and the Cordyceps militaris mushroom, both of which are non-animal sources. No animal-derived materials are involved in the fermentation or filtration process, making it appropriate for both vegans and vegetarians.
Pregnant or breastfeeding women are not currently flagged for any special caution when using products that contain this ferment, as it is applied topically and has minimal systemic absorption. Still, this is not medical advice; anyone who is expecting or nursing should review new skincare products with a qualified healthcare professional to be on the safe side.
Cordyceps Militaris/Germinated Soybean Ferment Extract Filtrate does not increase the skin’s sensitivity to sunlight, so it is not considered photosensitizing. Regular daily sunscreen is still essential for overall skin health.
Potential Side Effects/Adverse Reactions
Reactions to topical Cordyceps Militaris/Germinated Soybean Ferment Extract Filtrate can vary from person to person. The following is a list of potential side effects that could occur, though most users will not experience them when the ingredient is used correctly in a finished product.
- Mild redness or warmth shortly after application
- Itching or tingling in those with very sensitive skin
- Localized swelling in individuals allergic to soy
- Rare delayed irritation when layered with highly acidic exfoliants or strong retinoids
If you notice persistent discomfort, redness or other unwanted changes after applying a product that contains this ferment discontinue use and consult a healthcare professional.
Comedogenic Rating
Rating: 0–1 out of 5
This filtrate is water based and contains mostly low-molecular-weight peptides, amino acids and sugars that rinse away or absorb quickly without leaving a heavy residue. It has no thick oils, waxes or fatty alcohols that typically clog pores, so the likelihood of it trapping sebum or dead cells is minimal.
Because of this light profile the ingredient is generally suitable for people who are prone to acne or breakouts.
Formulators sometimes pair the ferment with richer emollients. In those finished products the overall pore-clogging potential will depend on the full ingredient list, not the ferment itself.
Summary
Cordyceps Militaris/Germinated Soybean Ferment Extract Filtrate conditions and protects the skin. Its peptides, sugars and amino acids boost surface hydration while natural antioxidants help shield against everyday environmental stress.
Although not yet a household name, it is gaining traction among brands that spotlight fermented or mushroom-derived actives, especially in K-beauty and barrier-care lines.
The ferment is considered very safe for topical use, with low irritation and virtually no comedogenicity in its pure form. As with any new skincare ingredient it is smart to patch test a product that contains this extract before applying it widely, just to be cautious.
