What Is Lentinus Edodes/Defatted Rice Bran/Sugar Cane Extract Ferment Extract?
Lentinus Edodes/Defatted Rice Bran/Sugar Cane Extract Ferment Extract is a naturally derived cosmetic ingredient produced by fermenting a mix of defatted rice bran and sugar cane juice with the mushroom Lentinus edodes, better known as shiitake. During fermentation the mushroom’s enzymes break down the plant material, creating smaller molecules like amino acids, peptides, sugars and antioxidants that are easily absorbed by skin. While rice bran and sugar cane have long histories in traditional beauty rituals, the idea of fermenting them with shiitake is comparatively new, growing popular in the last decade as Korean and Japanese formulators sought gentler, bio-available actives. The process begins by removing most of the oil from rice bran, blending it with sugar cane extract and inoculating the mixture with Lentinus edodes. Controlled warmth and humidity allow the culture to thrive for several days before the resulting liquid is filtered and stabilized. The finished extract is water-soluble, lightly tinted and carries a mild, earthy scent.
Because it is soothing and nutrient-rich, this ferment is added to a range of leave-on and rinse-off products. You may spot it in hydrating sheet masks, daily moisturizers, anti-aging serums, brightening essences and after-sun gels where it supports skin renewal and comfort.

Who Can Use Lentinus Edodes/Defatted Rice Bran/Sugar Cane Extract Ferment Extract
This ferment is gentle and water based so it tends to suit most skin types including dry, normal, combination, oily and sensitive skin. Because it is light and non greasy it does not clog pores, yet the amino acids and sugars give comforting hydration that dry or easily irritated skin appreciates. The only group that may need caution is anyone with a known allergy to mushrooms, rice or cane sugar, since the extract still carries trace compounds from those sources.
The ingredient is created from plant material and a mushroom culture with no animal by-products so it is considered suitable for vegans and vegetarians.
There are no specific studies showing risk for pregnant or breastfeeding women. It is not absorbed in meaningful amounts and has no documented hormone activity, so most experts judge it low concern. This is not medical advice; anyone who is pregnant or nursing should show the full product label to a healthcare professional before use just to be safe.
Lentinus Edodes/Defatted Rice Bran/Sugar Cane Extract Ferment Extract is not known to cause photosensitivity, so it will not make skin more prone to sunburn. Standard daytime sun protection is still recommended when using any skincare routine.

Comedogenic Rating
Rating: 1 / 5
This ferment is primarily water based, contains virtually no oils and features small, bio-available molecules. Because the rice bran is defatted and the sugars are lightweight humectants, the extract has little tendency to block pores. A conservative score of 1 is given rather than 0 because trace lipids from the plant material can remain after processing, though the amount is typically negligible.
Suitable for acne-prone or breakout-prone skin in most cases.
Formulas that combine this ingredient with heavier emollients may raise the overall comedogenicity, so the full product context still matters.
Summary
Lentinus Edodes/Defatted Rice Bran/Sugar Cane Extract Ferment Extract is used mainly for skin conditioning. Fermentation with shiitake enriches the mix with moisturizing sugars, barrier-supporting amino acids and protective antioxidants that leave skin soft, supple and calm.
The ingredient is gaining traction in K-beauty and indie formulas but is not yet as common as classics like aloe or green tea. Its gentle profile and plant-based origin make it appealing to clean beauty enthusiasts.
Topically it is considered very safe, with low risk of irritation unless a person is allergic to mushrooms, rice or cane sugar. As with any new skincare product, patch testing on a small area first is a smart way to rule out individual sensitivities.
