Science
Mechanism of Action
This extract functions primarily through its rich polysaccharide content, acting as a powerful humectant that draws and retains moisture within the skin, potentially surpassing hyaluronic acid's capacity. It creates a breathable, gel-like film on the skin's surface, effectively sealing in hydration and reducing trans-epidermal water loss (TEWL) to bolster the skin's natural barrier. Furthermore, it stimulates collagen production to improve elasticity and diminish fine lines, while its potent antioxidant properties neutralize free radicals and mitigate oxidative stress. The extract also possesses anti-inflammatory capabilities, soothing irritation by modulating immune responses and inhibiting pro-inflammatory cytokines, and may even contribute to evening skin tone by inhibiting melanogenesis.

Key findings
- 01 At concentrations of 0.01-0.02% (100-200 µg/ml), it demonstrated excellent antioxidative and cell-protective functions against hydrogen peroxide-induced skin fibroblast injury, supporting its role in combating oxidative stress.
- 02 A concentration of 0.05% (500 ppm) inhibited TNF-α expression, thereby suppressing inflammatory reactions and offering relief from UV-induced skin irritation.
- 03 In cosmetic formulations, it reduced Trans-Epidermal Water Loss (TEWL) by 12.4%, promoting adequate epidermal hydration and enhancing the skin barrier.

The Formula
Formulation
Stability
Optimal stability for commercial Tremella fuciformis polysaccharides (TPS) emulsions is observed at pH 6. For general cosmetic formulations, pH is frequently adjusted to 5.0–5.5 to ensure product stability.
Conflicts
- The addition of sodium gluconate before Tremella Fuciformis Sporocarp Extract during emulsion preparation may result in incomplete dissolution and the formation of undesirable lumps.
Safety
Safety Profile
Dermatological tests of formulations containing this extract showed no reported erythema, swelling, or irritation in human volunteers. EWG Skin Deep rates it as a 'low' concern across several categories (cancer, allergies, developmental toxicity). SkinSAFE classifies it as 'Irritant Free', 'Dye Free', 'Fragrance Free', 'Paraben Free', 'Lanolin Free', and 'Coconut Free', deeming it safe for various sensitive applications including 'Baby SAFE' and 'Eyelid SAFE'. The European Commission's CosIng database lists its functions without specific SCCS opinions on safety.
