Science
Mechanism of Action
Phellinus Linteus Extract functions by robustly neutralizing oxidative stress through free radical scavenging and preventing lipid peroxidation, thereby fighting skin aging. It actively reduces inflammation by inhibiting pro-inflammatory cytokines and suppressing key signaling pathways such as NF-κB and MAPK. Additionally, it promotes cellular renewal by stimulating new cell formation, supports skin barrier function with inherent ceramides, and may diminish hyperpigmentation by reducing melanin synthesis, similar to arbutin. It also demonstrates immunomodulatory activity via its polysaccharide-protein complexes.

Stability
Phellinus Linteus Extract comprises components soluble in both water, such as polysaccharides, and organic solvents like ethyl acetate. While the Phellinus linteus mycelia exhibit optimal growth in liquid cultures within a pH range of 5.0-7.0 (with some strains preferring pH 5.5 and others 7.0), specific stability data regarding the extract's optimal pH range in cosmetic formulations are currently unavailable.
Safety
Safety Profile
As of September 14, 2010, the Cosmetic Ingredient Review (CIR) identified Phellinus Linteus Extract as having 'No Reported Uses' in the FDA's Voluntary Cosmetics Reporting Program, thus requiring no further action for topical cosmetic use. Oral intake studies have demonstrated safety for consumption at 1000 mg/day, with no adverse reactions observed at doses up to 2000 mg/day. However, a case report noted that P. linteus use resulted in the worsening of an autoimmune skin condition called pemphigus. The SCCS has not assessed this ingredient.
