Tremella – the beauty mushroom: what it is and why it is associated with collagen

Tremella fuciformis is a mushroom that looks like white jelly hanging from a tree – and it is this gelatinous, translucent structure that holds the key to its unique properties. In traditional Chinese and Korean medicine, tremella has been used for over 2000 years as a beauty supplement that was said to keep the skin 'like that of the imperial concubine Yang Guifei' – a beauty considered an ideal during the Tang dynasty (8th century AD). Modern science has discovered that behind this legend lie real polysaccharides with strong moisturizing effects, comparable to hyaluronic acid. Is it really 'vegan hyaluronic acid'? How does tremella relate to collagen? And what exactly does its oral supplementation provide? This article answers these questions based on available scientific research.

KEY INFORMATION
• The polysaccharides in tremella have a molecular weight of about 100–400 kDa – lower than traditional hyaluronic acid (1500 kDa) – which allows for deeper penetration into the skin layers.
• A study by Wen et al. (Journal of Cosmetic Science, 2016) showed an increase in skin cell hydration of 22–35% and stimulation of NMF (natural moisturizing factor) in an in vitro model when using tremella extract.
• Tremella contains glucuronic acid and β-(1→3)-glucans – two key polysaccharides with documented water-binding and immunomodulating effects.
• Effective oral dosing: 1000–2000 mg of standardized extract daily for a minimum of 4–8 weeks, preferably in combination with collagen or vitamin C.

What is tremella and where does it grow?

Tremella fuciformis (snow fungus, white fungus, jelly fungus) is a uredinomycota – a parasitic fungus that grows on dead hardwood in the tropical and subtropical forests of East Asia, Latin America, and Africa. Its fruiting body has a characteristic gelatinous, multi-lobed structure that is white or cream-colored, resembling a jelly mushroom or cartilage. In its fresh state, it is almost transparent and shimmering. When dried, it shrinks to a whitish, paper-like flake.

In Chinese cuisine, tremella is an ingredient in traditional desserts, soups, and wellness drinks – especially the popular 'tremella and jujube' drink consumed as a daily beauty supplement. In traditional TCM, it is classified as a yin-tonifying agent: moisturizing, cooling, and strengthening the kidneys and lungs. Review by Ma et al. (International Journal of Biological Macromolecules, 2021) describes tremella as one of the medicinal mushrooms with the longest documented history of cosmetic and medical use.

How do the polysaccharides in tremella moisturize the skin – mechanism of action

The secret of tremella lies in its polysaccharides. The mushroom contains high concentrations of glucuronic acid and mannuronic xylan – long-chain polysaccharides that form a gel-like network binding water. The mechanism is similar to that of hyaluronic acid (HA), but with one key difference: the molecular weight of tremella polysaccharides is about 100–400 kDa, while native HA in the dermis has a weight of 1–1.5 MDa (megadalton).

This lower molecular weight translates to a better ability to penetrate the layers of the epidermis. High molecular weight HA applied to the skin creates a moisturizing film on the surface but does not penetrate deeper. Low molecular weight polysaccharides from tremella can reach the stratum spinosum of the epidermis and the dermis. Wen et al. (Journal of Cosmetic Science, 2016) tested tremella extract on keratinocyte cultures and demonstrated a 30–45% increase in the expression of AQP3 (aquaporin-3 – a water channel in skin cells), which translated to a 22–35% increase in cellular hydration.

Our observations: Tremella as an oral supplement is particularly interesting for those who have dry skin despite external moisturizing with cosmetics. Hydration 'from the inside' through tremella polysaccharides addresses the issue of the skin's inability to retain water, not just the lack of an external moisturizer. In practice, users describe their skin as 'softer from within' after 4–6 weeks of taking 1500 mg of extract daily.

Why is tremella associated with collagen?

The combination of tremella + collagen is one of the most thoughtfully designed stacks in beauty supplementation. The mechanisms of both ingredients are complementary and mutually reinforcing.

Collagen (especially hydrolyzed type I and III collagen) provides amino acids (glycine, proline, hydroxyproline), which are direct substrates for fibroblasts synthesizing new collagen in the dermis. Clinical studies show that oral supplementation with hydrolyzed collagen at 2.5–10 g/d for 8–12 weeks improves skin elasticity and reduces wrinkles. Proksch et al. (Skin Pharmacology and Physiology, 2014) demonstrated in an RCT with 69 women an increase in skin elasticity of 7% and improvement in hydration after 8 weeks of 2.5 g of hydrolyzed collagen daily.

Tremella complements the action of collagen in two ways: first, the polysaccharides in tremella hydrate the extracellular matrix, creating an optimal environment for the synthesis of new collagen (fibroblasts need a properly hydrated ECM to work effectively). Second, tremella may inhibit MMP-1 and MMP-3 – matrix metalloproteinases that break down collagen – which slows the catabolism of collagen already present in the skin. The combination means: collagen provides building blocks + tremella provides the environment and inhibits breakdown = double support for the skin.

Tremella and dry and atopic skin – what does research say?

Dry skin and atopic dermatitis (AD) are two conditions where tremella polysaccharides may have particular applications. In AD, a key pathological mechanism is the disruption of epidermal barrier function – reduced production of ceramides, filaggrin, and NMF (Natural Moisturizing Factor) leads to excessive transepidermal water loss (TEWL).

Tremella polysaccharides, by stimulating AQP3 and NMF, may supplement the deficit of water-binding factors in atopic skin. Badanie Wu et al. (Biomolecules, 2022) evaluated the impact of oral supplementation with tremella polysaccharides on mice with induced AD and showed a significant reduction in TEWL, decreased inflammation, and improved integrity of the epidermal barrier. This is an animal model, but the biological mechanism is credible for translation to human clinics.

For dry skin, without atopy, tremella can be a valuable addition to a moisturizing diet. Instead of relying solely on occlusive creams (petrolatum, shea butter) that block water evaporation from the skin, tremella improves the skin cells' ability to retain water – addressing the cause, not just the symptom of dryness. Oral tremella polysaccharides reach the dermis through circulation and act directly on fibroblasts and keratinocytes, which distinguishes them from moisturizing creams that work only on the surface.

Tremella and Immunity – Immunomodulating Effects of β-Glucans

Tremella is not just a "beauty" supplement – its β-glucans exhibit immunomodulating effects similar to other medicinal mushrooms. β-(1→3)-glucans from tremella activate the Dectin-1 receptor on macrophages and dendritic cells, stimulating the production of pro-inflammatory cytokines and activating the innate response against pathogens.

The polysaccharides of tremella also exhibit anti-proliferative effects against cancer cells in vitro – particularly against breast cancer cells and HeLa cells. Badanie Chen et al. (International Journal of Molecular Sciences, 2017) It has been shown that the polysaccharides of tremella inhibit the proliferation of HeLa cells by inducing apoptosis and halting the cell cycle in the G2/M phase. This is an in vitro study – there are no clinical data – but it demonstrates the broad biological effects of this mushroom beyond cosmetics.

From a practical point of view: tremella used as a beauty supplement automatically provides immunomodulating β-glucans. This means that a daily intake of 1000–2000 mg of tremella extract simultaneously supports the skin and the immune system – two effects in one capsule. The synergy of tremella + reishi (additional immunomodulator + adaptogen) is described by users of wellness protocols focused on skin and immune support during the fall and winter.

Tremella and Skin Aging – Antioxidant Action

Skin aging has two main mechanisms: chronic aging (genetically programmed) and photoaging (caused by UV and oxidative stress). Tremella addresses the latter through its antioxidant properties. The polysaccharides of tremella demonstrate radical scavenging activity in DPPH, ABTS, and superoxide dismutase (SOD) tests. Wen et al. (2016) They showed that tremella extract at a concentration of 200 μg/ml exhibits 68% DPPH radical scavenging activity – comparable to vitamin E under the same conditions.

In the context of photoaging, it is interesting to note the inhibition of MMP by tremella. UVA radiation activates MMP-1 in skin fibroblasts, leading to collagen degradation and wrinkle formation. If the polysaccharides of tremella inhibit MMP-1 both through an antioxidant mechanism (scavenging ROS that activate NF-κB) and through direct enzyme inhibition, their photoprotective action is biologically credible. This is an area that requires further clinical research in humans.

How to choose a good tremella supplement – what to pay attention to?

The tremella supplement market is still relatively niche in Europe, but the availability of products is rapidly increasing. The quality of products varies – it's important to know what to look for when purchasing.

First: forma surowca. The best products use tremella fruiting bodies, not mycelium grown on grain substrates. Mycelium on grains has a lower content of active polysaccharides and a higher starch content from the substrate. The label should state "Tremella fuciformis fruiting body extract" or "extract from snow mushroom fruiting body".

Second: standardization of polysaccharides. Good products indicate the percentage of polysaccharides (minimum 20–30%) or β-glucans. Products without information on standardization may contain low-quality raw materials.

Po trzecie: metoda ekstrakcji. Hot water extract is optimal for tremella because polysaccharides are hydrophilic. Alcohol extracts are unnecessary – the active ingredients of tremella are not lipophilic like, for example, erinacines in lion's mane. "Dual extraction" products for tremella do not provide a significant advantage over the hot water extract alone.

Tremella used externally in cosmetics is a separate category. A tremella serum at 1–3% acts as a surface humectant and is an alternative to hyaluronic acid serum – more biodegradable and "plant-based". It can be used both orally and externally at the same time, combining both moisturizing effects.

Tremella and collagen – how to use them together?

Oral protocol for the tremella + collagen combination: collagen hydrolysate 2.5–5 g daily (morning or evening – timing is not clinically significant) + tremella extract 1000–2000 mg daily with a meal. Both supplements should be taken for a minimum of 8 weeks to assess effects – the first visible changes in skin hydration are often reported after 4–6 weeks.

An important addition is vitamin C (minimum 200 mg/d) as a cofactor for prolyl endopeptidase and prolyl-4-hydroxylase – enzymes necessary for the synthesis of hydroxyproline in collagen. Without vitamin C, collagen synthesis is impaired even with optimal amino acid supply from the hydrolysate. The tremella + collagen + vitamin C set is a complete supplementation protocol to support the skin from within. The effects of oral supplementation are subtler and slower than cosmetic preparations, but deeper – addressing cellular mechanisms, not just the surface.

Tremella as a functional mushroom with a beauty profile complements the effects of reishi described in the article. Reishi – the mushroom of immortality for immunity and stress.

Typical "inside-out beauty" protocol for 8 weeks: tremella 1500 mg in the morning + collagen hydrolysate 5 g at any time + vitamin C 200–500 mg + reishi 500–1000 mg in the evening. This combination addresses skin hydration (tremella + collagen), immunity (reishi + β-glucans from tremella), and collagen synthesis (vitamin C as a cofactor). It is a concentrated but safe protocol for healthy adults. User-reported effects on the skin: softer, better-hydrated skin after 4–6 weeks, reduced visibility of fine lines with proper overall hydration, better elasticity under pressure. Remember that supplements cannot replace the basics: hydration (minimum 1.5–2 liters of water daily), a diet rich in antioxidants, and sun protection are the foundation of healthy skin, on which beauty supplements build additional effects.

Frequently Asked Questions

What is tremella and why is it called the beauty mushroom?

Tremella fuciformis is a gelatinous white mushroom rich in moisturizing polysaccharides, used in Asia as a beauty supplement for over 2000 years. It contains glucuronic acid and β-glucans, which act similarly to hyaluronic acid. In Chinese culture, it is an iconic ingredient in beauty diets – for centuries, the legendary beauty Yang Guifei consumed it at the Tang dynasty court. History attributes her eternal youth to the regular consumption of tremella and lotus leaves in the form of drinks and desserts. Although this is a legend, its biochemical basis – water-binding polysaccharides – is very real.

How does tremella moisturize the skin?

Tremella polysaccharides (100–400 kDa) are smaller than HA (1500 kDa), allowing for deeper penetration into the skin layers. They stimulate the production of aquaporin-3 (water channel in skin cells) by 30–45% and increase cellular hydration by 22–35% according to Wen et al. (2016). Orally, they act "from the inside" on the extracellular matrix.

Why is tremella associated with collagen?

The mechanisms are complementary: collagen provides the amino acids that build the skin matrix, tremella hydrates the extracellular matrix and inhibits enzymes (MMP) that break down collagen. Together, they provide double support – building blocks and an environment for their action. The combination with vitamin C as a cofactor for collagen synthesis creates a complete protocol.

Jakie dawkowanie tremelli jest skuteczne?

Orally: 1000–2000 mg of standardized extract daily for a minimum of 4–8 weeks. Externally: cosmetic products with tremella at a concentration of 1–5% act as surface moisturizers. Combining oral and external routes yields the best results – each route addresses a different layer of the skin.

Does tremella have anti-aging effects?

Laboratory studies confirm the inhibition of MMP-1 and MMP-3 (collagen-degrading enzymes), antioxidant activity (DPPH scavenging 68% at 200 μg/ml), and stimulation of AQP3. There are no large clinical RCTs in humans – most data comes from in vitro studies. The mechanisms are biologically plausible but require confirmation in clinical trials.

Does tremella have antioxidant properties?

Tak – Wen et al. (2016) demonstrated DPPH radical scavenging activity comparable to vitamin E at a concentration of 200 μg/ml. The antioxidant action of tremella complements its moisturizing effects, protecting the skin from photoaging and oxidative damage.
