What Is Hydrolyzed Tremella Fuciformis Polysaccharide?
Hydrolyzed Tremella Fuciformis Polysaccharide is a carbohydrate extract derived from Tremella fuciformis, a translucent fungus traditionally used in East Asian skincare and cuisine. The ingredient is broken down (hydrolysed) into smaller molecular chains to improve its ability to penetrate and distribute throughout the skin.
In skincare formulations, it functions as both a humectant and an emollient. As a humectant, it absorbs water from the environment and deeper skin layers, helping to bind moisture to the stratum corneum. This dual action makes it useful in hydrating formulas where water retention is the primary goal.
How It Works
Hydrolyzed Tremella Fuciformis Polysaccharide works through humectant action. Its molecular structure contains multiple hydroxyl groups that attract and bind water molecules, drawing moisture from the dermis toward the epidermis and from the air into the skin. This helps prevent transepidermal water loss and improves overall skin hydration levels.
The ingredient also forms a light emollient film on the skin surface, which reduces moisture evaporation and contributes to a smoother feel without occluding pores or creating heaviness.
Clinical Evidence & References
Evidence on this ingredient remains relatively limited in published clinical literature. Most data comes from cosmetic chemistry and stability studies rather than large-scale human trials. Tremella Fuciformis itself has a long history of use in traditional skincare, which suggests a reasonable safety profile, though this does not constitute clinical proof of efficacy.
Where testing has been undertaken, results suggest the ingredient performs adequately as a hydrating agent and skin conditioning substance. More robust clinical data comparing it to other humectants would strengthen confidence in its specific benefits, but current evidence does not contradict its role as a moisturising support ingredient.
How to Use
Hydrolyzed Tremella Fuciformis Polysaccharide is typically found in serums, essences, toners, and hydrating lotions. It works well as part of a layered routine: apply to damp skin before heavier creams or oils to maximise water absorption. There is no minimum or maximum frequency — it can be used twice daily in products formulated for daily use. Pairing it with occlusives like glycerin or plant oils will enhance its hydrating effect.
