Poria Cocos Sclerotium Extract

Poria Cocos Sclerotium Extract comes from the sclerotium (the dense, hardened mass) of Poria Cocos, a fungus that has been used in traditional Chinese medicine and food for over 2000 years. The extract is typically obtained through ethanol extraction and contains bioactive compounds including triterpene acids.In skincare formulations, this ingredient functions as an astringent and is thought to work through multiple pathways related to skin hydration and barrier health. It appears in roughly 0.1% of skincare products, suggesting it remains relatively uncommon in Western formulations.

The extract appears to work primarily by stimulating the production of aquaporin-3 (AQP3) in skin cells through the PI3K/Akt/mTOR signaling pathway. Aquaporins are water-channel proteins that facilitate water transport across cell membranes, which is critical for maintaining hydration and barrier function in the epidermis.Additionally, the triterpene acids present in Poria Cocos—including pachymic acid and poricoic acid B—have been shown in laboratory studies to modulate inflammatory responses by inhibiting certain inflammatory pathways, though their effects in real-world skincare use remai…

Poria Cocos Sclerotium Extract is typically incorporated into serums, toners, creams, and hydrating treatments. Since this ingredient is generally combined with other hydrating and barrier-supporting compounds, use it as directed within your regular skincare routine. It integrates well with other hydrating ingredients but no specific interaction concerns have been documented.

Poria Cocos has a long history of safe use in traditional medicine and food applications. No significant safety concerns have been documented in cosmetic use, though as with any ingredient, patch testing is advisable if you have known sensitivities to fungi or mushroom-derived compounds.
