What Is Trametes Hirsuta Extract?
Trametes Hirsuta Extract comes from Trametes hirsuta, a small bracket fungus that grows on trees in temperate forests. The extract is rich in natural sugars, amino acids and soothing polysaccharides that help bind water to the skin. Traditional herbalists have used similar tree fungi to care for skin for centuries, but it was only in the last few decades that lab testing confirmed their softening and calming properties. Cosmetic chemists now draw on this knowledge to include Trametes Hirsuta Extract in modern formulas.
The process starts with sustainably harvested fruiting bodies of the fungus. They are dried, finely ground, then soaked in a mix of water and gentle food-grade solvents. The liquid is filtered, concentrated and purified to remove any unwanted particles while keeping the active molecules intact. The finished extract is a clear to pale brown liquid that blends easily with other skincare ingredients.
You will most often see Trametes Hirsuta Extract in hydrating sheet masks, daily moisturizers, night creams, soothing after-sun lotions, anti-aging serums and leave-on treatments for sensitive or dry skin. Its mild nature makes it suitable for face and body products alike.
Trametes Hirsuta Extract’s Cosmetic Benefits/Uses
When added to skincare, Trametes Hirsuta Extract offers two key roles
- Skin Conditioning: The extract helps balance moisture levels, leaving skin feeling smoother and more supple. Its natural sugars attract water while its amino acids support a healthy skin barrier, which can reduce roughness and improve overall tone
- Emollient: It forms a light, breathable film on the surface that softens dry patches and gives formulas a silky glide. This makes creams easier to spread and helps lock in moisture for longer comfort
Who Can Use Trametes Hirsuta Extract
Trametes Hirsuta Extract is gentle enough for most skin types. Dry, normal and combination complexions usually benefit the most thanks to its moisture-binding sugars and softening film. Oily or acne-prone skin can also use it because it is lightweight and does not clog pores, though those users may prefer formulas that pair the extract with oil-control ingredients. Highly reactive or allergy-prone skin should always start with low concentrations to confirm comfort.
The extract is derived entirely from a tree-growing fungus and no animal by-products are involved in the harvesting or processing steps, making it suitable for both vegans and vegetarians.
There is no published evidence suggesting that topical Trametes Hirsuta Extract poses a problem for pregnant or breastfeeding women when used in normal cosmetic amounts. This is not medical advice and anyone who is pregnant or nursing should show the product to a qualified healthcare professional before use just to be safe.
The ingredient does not increase photosensitivity so daytime application does not require extra sun precautions beyond a good broad-spectrum sunscreen. It is also fragrance free by nature and has a neutral scent, which may be helpful for users sensitive to added perfume.
Potential Side Effects/Adverse Reactions
Side effects and reactions to topical Trametes Hirsuta Extract can vary from person to person. The following list covers potential issues, but they are uncommon when the ingredient is properly formulated and used as directed.
- Redness or stinging: A brief flushing or mild burn can occur on very sensitive skin
- Itchy rash or hives: Users with an existing mushroom allergy may experience an immune response
- Contact dermatitis: Prolonged irritation or dry patches may appear if the product includes other aggressive actives or preservatives that do not agree with the skin
- Eye irritation: If the product migrates into the eyes it can trigger watering and discomfort
If any of these effects appear stop using the product and seek guidance from a medical professional
Comedogenic Rating
Rating: 0 / 5
Trametes Hirsuta Extract is a water-based ingredient with virtually no oils or waxy residues that could block pores. Its main components are lightweight sugars, amino acids and polysaccharides that dissolve readily in water, so they rinse clean without leaving a film that traps sebum or dead cells. For that reason it earns a solid 0 rating, meaning it is considered non-comedogenic.
Because of this low score it is generally suitable for people who are prone to acne or breakouts.
No special interactions with typical acne treatments such as salicylic acid or benzoyl peroxide have been reported, so it can be layered with most blemish-fighting routines without extra risk of clogging.
Summary
Trametes Hirsuta Extract works mainly as a skin-conditioning and emollient agent. Its natural sugars draw moisture toward the surface, its amino acids help strengthen the skin barrier and its polysaccharides create a thin smoothing veil that leaves skin soft and comfy.
While it is not yet a household name like hyaluronic acid or aloe vera, interest in mushroom-based skincare has been climbing, so you will likely see this extract in more hydrating serums, masks and creams over the next few years.
Current research and consumer reports show it is safe for most users, including vegans and those with sensitive skin. As with any new cosmetic ingredient it is smart to patch test a small area first to confirm your skin feels happy before applying it to larger zones.
