What Is Tuber Aestivum Extract?
Tuber Aestivum Extract is derived from the summer truffle, a fungus that grows underground in symbiosis with tree roots. The extract contains compounds including polysaccharides, proteins, and phenolic substances that have been studied for their potential effects on skin.
In skincare formulations, this ingredient functions primarily as a skin protectant and conditioning agent, helping to support the skin's barrier and overall appearance.
How It Works
Tuber Aestivum Extract appears to work through multiple mechanisms. The polysaccharides present in the extract have hygroscopic properties, meaning they can help skin retain moisture. Additionally, the phenolic compounds contribute antioxidant activity, which may help neutralise free radicals that contribute to skin ageing.
The extract also contains amino acids and proteins that condition the skin surface, contributing to improved texture and appearance.
Clinical Evidence & References
Research on Tuber Aestivum Extract specifically in skincare is limited. Most studies examining truffle extracts have focused on their antimicrobial and antioxidant properties in food science rather than dermatological applications.
The ingredient is included in skincare formulations based on its general composition and traditional use, but robust clinical trials demonstrating efficacy in human skin are lacking. Further research would be needed to establish specific benefits and optimal concentrations for skincare use.
How to Use
Tuber Aestivum Extract is typically incorporated into serums, moisturisers, and face masks. There is no established upper limit for usage frequency; products containing this ingredient can generally be used as directed by the manufacturer. It integrates well into most skincare routines and does not require special application techniques.
