Science
Mechanism of Action
The extract is rich in polysaccharides that form a microscopic, protective film on the skin's surface, bolstering the skin barrier and significantly limiting trans-epidermal water loss (TEWL) for prolonged hydration. Its impressive water-retention capacity, reportedly holding up to 500 times its weight in water, facilitates multi-layer hydration to both the stratum corneum and dermis, offering performance comparable to or superior to hyaluronic acid. Beyond hydration, it effectively neutralizes free radicals, thereby enhancing resistance to oxidative stress and offering protection against UV-induced photoaging and collagen degradation. It exhibits anti-inflammatory properties by modulating immune responses and inhibiting pro-inflammatory cytokines. Furthermore, it promotes wound healing, stimulates ceramide synthesis crucial for barrier repair, and provides anti-glycation action to protect collagen from Advanced Glycation End-products (AGEs). The extract also inhibits melanogenesis by decreasing melanin content and tyrosinase expression, and supports anti-wrinkle effects through increased type I procollagen synthesis and reduced matrix metalloproteinase 1 (MMP-1) expression, partly by upregulating SIRT1 expression to alleviate oxidative stress and apoptosis in skin fibroblasts.

Key findings
- 01 In concentrations ranging from 100-300 µg/mL (in vitro), this extract significantly reduced melanin content and tyrosinase expression in B16F10 cells, demonstrating skin brightening effects.
- 02 At concentrations of 100-300 µg/mL (in vitro), it promoted wound healing in human HaCaT keratinocytes and Detroit 551 fibroblasts, also reducing oxidative stress and apoptosis in skin fibroblasts, with a maximum anti-stress effect observed at 200 µg/mL via SIRT1 upregulation.
- 03 Formulations incorporating Tremella fuciformis extract were shown to reduce Trans-Epidermal Water Loss (TEWL) by 12.4% in human volunteers, thereby enhancing epidermal hydration.
- 04 Further studies indicated decreased melanin content and tyrosinase activity, down-regulation of mRNA expression for melanin formation factors (MITF, TRP-1, TRP-2), increased synthesis of type I procollagen, and reduced mRNA expression of matrix metalloproteinase 1 (MMP-1) in human dermal fibroblasts, collectively supporting skin whitening and anti-wrinkle actions.

The Formula
Formulation
Stability
Emulsions containing this extract exhibit stability when formulated with a pH adjusted between 5.0-5.5. The polysaccharides of Tremella fuciformis generally show stability across a wide pH range (e.g., 3.0, 6.5, and 10) in emulsions. For optimal processing, the active ingredient should be added during the emulsion preparation stage, ensuring complete dissolution to prevent lump formation.
Conflicts
- Sodium gluconate (if added before the extract, may lead to incomplete dissolution and lumps)
Safety
Safety Profile
Extensive data suggests Tremella fuciformis extract is perfectly safe for both ingestion and topical application. Dermatological tests on 20 human volunteers confirmed no erythema or irritation, indicating excellent skin compatibility. Tremella polysaccharide is widely recognized as a safe and non-toxic natural active product.
