Tremella Fuciformis is a translucent mushroom, sometimes called 'snow fungus,' that's been used in traditional Asian skincare for centuries. In modern skincare, its extract is valued for its natural polysaccharides, which help the skin retain moisture and maintain a plump, hydrated appearance.
Benefits
- Hydration and moisture retention
- May improve skin elasticity and firmness
- Antioxidant properties to protect against environmental stressors
Science: Limited peer-reviewed data available for this ingredient. Traditional use and preliminary in vitro studies suggest hydrating and antioxidant potential, but robust clinical trials in human subjects are sparse.

Glyceryl Glucoside is a humectant derived from natural sources that helps skin retain moisture by supporting aquaporin-3, a protein channel that regulates water movement in skin cells. It works to strengthen the skin barrier and improve hydration levels.
Benefits
- Enhances skin hydration and moisture retention
- Supports skin barrier function
- May help regulate skin cell proliferation and migration
Science: Recent research (2024) demonstrates that Glyceryl Glucoside effectively increases aquaporin-3 expression in keratinocytes and enhances cell migration while reducing hyperproliferation in inflammatory skin models, suggesting potential benefits for barrier-compromised skin conditions.
