What Is Lactobacillus/Phellinus Linteus Mycelium/Rice Ferment Extract?
Lactobacillus/Phellinus Linteus Mycelium/Rice Ferment Extract is a naturally derived ingredient made from simple rice grains that have been fermented with two friendly microorganisms: Lactobacillus, a well known probiotic bacterium, and Phellinus linteus, a mushroom species prized in traditional East Asian wellness practices. During fermentation these microbes break down the starches, proteins and lipids in rice into smaller molecules such as amino acids, peptides, sugars and beneficial organic acids. The result is a fluid rich in skin supporting nutrients and antioxidants.
The use of fermented rice water for beauty dates back centuries in Japan and Korea where it was prized for its softening properties. Modern cosmetic chemists built on this heritage by adding probiotic bacteria and mushroom mycelium to boost the bioactive profile and stability of the extract. The manufacturing process starts with steamed rice that is inoculated with cultures of Lactobacillus and Phellinus linteus. The mixture is kept in controlled warm conditions for several days while the microbes grow and ferment the rice. After reaching the desired activity the mash is filtered, and the liquid portion is purified, concentrated and finally standardized so each batch delivers consistent performance.
You can find Lactobacillus/Phellinus Linteus Mycelium/Rice Ferment Extract in a variety of leave-on and rinse-off products. It often appears in hydrating toners, lightweight serums, sheet masks, anti aging creams, soothing gels and even scalp treatments where brands want to deliver gentle conditioning along with a touch of probiotic inspired care.

Who Can Use Lactobacillus/Phellinus Linteus Mycelium/Rice Ferment Extract
This fermented rice extract is gentle and lightweight so it suits most skin types including dry, normal, combination and oily. Its water like texture sinks in quickly without leaving a greasy film which makes it comfortable for those prone to shine. Sensitive skin usually tolerates it well thanks to the soothing by products of fermentation, though anyone with a known allergy to mushrooms or rice should proceed with extra care.
The ingredient is produced from plant grain and microbial cultures with no animal derived additives so it is considered vegan and vegetarian friendly.
Current research shows no specific hazards for women who are pregnant or breastfeeding when the extract is used topically in normal cosmetic amounts. This is not medical advice and anyone expecting or nursing should show the full product ingredient list to a qualified health professional before adding it to a routine.
Lactobacillus/Phellinus Linteus Mycelium/Rice Ferment Extract does not increase photosensitivity so there is no extra need for sun avoidance beyond everyday SPF habits.
Potential Side Effects/Adverse Reactions
Side effects from topical use of Lactobacillus/Phellinus Linteus Mycelium/Rice Ferment Extract vary from person to person. The points below list potential reactions, though most users experience none of them when the ingredient is correctly formulated and preserved.
- Mild stinging or redness in very sensitive skin, usually short lived and resolving once the product absorbs
- Allergic contact dermatitis in individuals allergic to rice, mushrooms or fermentation by products
- Breakouts or congestion if the finished product also contains heavy occlusive agents that do not suit acne prone skin
- Texture or odor changes in poorly preserved formulas which can signal microbial contamination and raise irritation risk
If any persistent burning, swelling or rash develops stop use immediately and consult a healthcare professional.
Comedogenic Rating
Rating: 0 / 5
This fermented rice extract is almost entirely water soluble and contains very little oil or wax so it does not create an occlusive film that could trap dead skin cells inside pores. The breakdown products of fermentation, such as amino acids and lightweight sugars, rinse away or absorb without leaving residue. For that reason it is considered non-comedogenic and is generally suitable for skin that is prone to acne or breakouts. The only caveat is the finished formula: if the extract is blended with heavy butters or rich silicones the overall product may still clog pores even though the extract itself does not.
Summary
Lactobacillus/Phellinus Linteus Mycelium/Rice Ferment Extract works primarily as a skin-conditioning agent. During fermentation the rice grains are converted into a cocktail of moisturizing sugars, free amino acids, peptides and organic acids. When applied to skin these molecules attract water, smooth the surface and supply mild antioxidant support which helps keep the moisture barrier comfortable and resilient.
The ingredient is a rising star in K-beauty and niche clean formulations but it is still less common than big-name ferments like galactomyces or bifida. Brands that use it often highlight the dual probiotic plus mushroom heritage to stand out in a crowded market.
Overall safety is high with very low irritation or sensitization rates. Still, every formula is unique so it is wise to patch test any new product that contains the extract before full-face use, especially if you have reactive skin.
