What Is Ganoderma Lucidum/Salix Gracilistyla Stem Ferment Extract Filtrate?
Ganoderma Lucidum/Salix Gracilistyla Stem Ferment Extract Filtrate comes from a partnership between a medicinal mushroom and a willow plant. The process starts with stems of Salix gracilistyla, a type of willow tree known for its natural salicylic compounds. These stems are placed in a controlled environment and fermented with Ganoderma lucidum, the famed “reishi” mushroom that has long been valued in East Asian wellness practices. During fermentation the mushroom breaks down plant material, releasing a mix of polysaccharides, amino acids and antioxidant molecules. Once fermentation is complete the liquid is carefully filtered to remove solids, leaving a clear filtrate rich in skin-friendly compounds.
The idea of combining botanicals with mushroom fermentation gained traction as Korean skin care labs searched for gentle yet potent antioxidants. By the early 2010s this filtrate began turning up in sheet masks and premium lotions, praised for delivering the soothing traits of willow along with the vitality boost linked to reishi. Today formulators add it to lightweight serums, anti-aging creams, after-sun products and calming mists where an extra layer of antioxidant protection is desired.
Ganoderma Lucidum/Salix Gracilistyla Stem Ferment Extract Filtrate’s Cosmetic Benefits/Uses
This ingredient is valued in skin care for one main reason: its antioxidant power.
As an antioxidant it helps neutralize free radicals that form when skin is exposed to UV light, pollution or stress. By reducing this oxidative strain the filtrate can support a brighter look, help maintain firmness and guard against early signs of aging. In daily formulas it works alongside other protective agents to keep the complexion looking fresh and resilient.
Who Can Use Ganoderma Lucidum/Salix Gracilistyla Stem Ferment Extract Filtrate
This filtrate is generally well tolerated by all skin types. Its light watery texture suits oily and combination skin without feeling heavy, while the soothing antioxidants can comfort dry or sensitive complexions. The only group that should be cautious are people with known allergies to mushrooms or willow bark, as cross-reactivity is possible.
The ingredient is plant and fungus derived with no animal by-products involved in the fermentation or extraction steps, so it fits within vegan and vegetarian standards.
Current data shows no specific issues for those who are pregnant or breastfeeding. That said this is not medical advice and anyone expecting or nursing should check with a healthcare professional before adding new skincare to their routine.
The filtrate does not make skin more prone to sunburn and can be used day or night without raising photosensitivity. It also has a negligible scent and is free of added dyes making it a low-irritation choice for people avoiding fragrances or colorants.

Comedogenic Rating
Rating: 0–1 (essentially non-comedogenic)
This filtrate is a water-light liquid with no heavy oils, waxes or butters that could block pores. The molecules it delivers—mostly antioxidants, amino acids and polysaccharides—are small and water soluble so they rinse or absorb without leaving an occlusive film. Formulators usually include it at low to moderate percentages, further reducing any clogging risk.
Because of this, it is generally suitable for skin that is prone to acne or frequent breakouts.
If the finished product also contains richer emollients or silicones the overall formula, not the filtrate itself, may influence pore congestion so always consider the full ingredient list.
Summary
Ganoderma Lucidum/Salix Gracilistyla Stem Ferment Extract Filtrate acts mainly as an antioxidant, helping neutralize free radicals created by UV rays and pollution. The fermentation step unlocks skin-friendly polysaccharides and amino acids that add a light soothing effect, supporting a more even tone and comfortable feel.
While not a household name, it has gained quiet popularity in Korean and niche clean-beauty formulas where gentle plant-mushroom synergies are prized. You will often spot it in serums, lotions and calming masks aimed at early aging concerns or stressed skin.
Current evidence points to a high level of safety with low irritation potential for most users. As with any new skin care product, do a quick patch test first to make sure your skin agrees with the overall formula.
