What Is Ganoderma Lucidum/Salix Gracilistyla Leaf/Stem Ferment Extract Filtrate?
Ganoderma Lucidum/Salix Gracilistyla Leaf/Stem Ferment Extract Filtrate is a fermented blend of willow leaves and stems with the well-known reishi mushroom. The process starts by steeping the plant material of Salix gracilistyla in water or a mild solvent, then adding the fungus Ganoderma lucidum so it can break down the plant cell walls during fermentation. After the mixture has matured, it is carefully filtered to remove solids, leaving a clear liquid rich in water-soluble nutrients, small peptides, and antioxidant molecules produced during fermentation.
The two natural sources have a long history in traditional self-care. Willow has been used for its soothing qualities, while reishi is prized in East Asia for helping the body handle stress. Modern formulators noticed that fermenting the two together boosts the overall antioxidant capacity and makes the blend easier for skin to absorb. First appearing in niche Korean skincare lines, the filtrate is now added to a growing range of global products.
You will most often spot this ingredient in leave-on items like serums, essences, ampoules, sheet masks, lightweight moisturizers, eye creams, and anti-aging lotions where steady antioxidant support is desired.
Ganoderma Lucidum/Salix Gracilistyla Leaf/Stem Ferment Extract Filtrate’s Cosmetic Benefits/Uses
This ferment filtrate is included for its antioxidant activity, helping to neutralize unstable molecules on the skin surface. By reducing oxidative stress it can support a brighter tone, help guard collagen from environmental damage and improve the overall resilience of the skin when used regularly in a well-formulated product.
Who Can Use Ganoderma Lucidum/Salix Gracilistyla Leaf/Stem Ferment Extract Filtrate
This fermented filtrate is gentle enough for most skin types. Its water-light texture and noncomedogenic nature make it suitable for oily, combination, normal and dry skin, while the absence of added fragrance in many formulas keeps it friendly for sensitive skin. The only group that might need extra caution is anyone with a known allergy to mushrooms, willow or natural salicylates, since those sensitivities could translate to topical reactions.
The ingredient is derived from plant leaves, plant stems and a fungus, with no animal by-products involved, so it aligns with vegan and vegetarian lifestyles.
There are no publicly documented concerns for pregnant or breastfeeding individuals when this ferment is used topically in cosmetic concentrations. Still, this is not medical advice and anyone who is pregnant or nursing should run new skincare products past a qualified doctor first just to be safe.
The filtrate does not increase photosensitivity. In fact its antioxidant content can help buffer the skin against everyday environmental stress, though a broad-spectrum sunscreen is still essential for daytime protection.
It layers well with most other skincare ingredients and tends to play nicely under makeup, making it an easy addition to both morning and evening routines.
Potential Side Effects/Adverse Reactions
Responses to topical Ganoderma Lucidum/Salix Gracilistyla Leaf/Stem Ferment Extract Filtrate vary from person to person. The effects listed below are only potential issues and are unlikely for the typical user when the ingredient is formulated and used as intended.
- Redness or mild irritation
- Allergic contact dermatitis in those sensitive to mushrooms, willow or salicylates
- Stinging sensation if applied to freshly exfoliated or broken skin

If you experience any of these reactions stop using the product and consult a healthcare professional or dermatologist.
Comedogenic Rating
Rating: 0/5. This ferment filtrate is predominantly water based and contains no pore clogging oils or waxes. Its molecules are small and lightweight, so they do not accumulate inside follicles or create an occlusive film. For this reason it is considered non-comedogenic and is generally suitable for people prone to acne or breakouts. The only caveat is that real-world formulas may pair the filtrate with richer emollients, so always look at the full ingredient list.
Summary
Ganoderma Lucidum/Salix Gracilistyla Leaf/Stem Ferment Extract Filtrate serves mainly as an antioxidant. The fermentation process breaks down willow and reishi compounds into smaller fragments and peptides that are easier for skin to absorb, where they help neutralize free radicals and support a more even tone and resilient barrier. Once a niche inclusion in Korean essences it is now popping up in global serums, eye creams and light moisturizers, though it is still far from a mainstream staple.
Topical use in cosmetic concentrations is considered low risk for most people, with the main precautions being mushroom or salicylate allergies. As with any new skincare product it is smart to patch test first to rule out individual sensitivities.
