Science
Mechanism of Action
This extract exerts its multi-faceted benefits through a rich composition of polyphenols, triterpenes, beta-glucans, melanin, and superoxide dismutase (SOD). It functions as a powerful antioxidant, neutralizing free radicals and shielding skin cells from oxidative stress and environmental aggressors, thereby mitigating premature aging. Its anti-inflammatory properties reduce redness and irritation by modulating pro-inflammatory cytokines, addressing concerns like acne and rosacea. Furthermore, it strengthens the skin's protective barrier, enhances elasticity, and significantly boosts hydration through humectant polysaccharides. The extract actively supports increased production of collagen, elastin, and hyaluronic acid while inhibiting their degradation, leading to a firmer, more supple complexion. Certain components also demonstrate tyrosinase inhibitory activity, contributing to a reduction in hyperpigmentation, and it may help balance sebaceous gland activity.

Key findings
- 01 In human fibroblasts, treatment led to a 69.5% improvement in cell viability post-hydrogen peroxide exposure and enhanced collagen synthesis by inhibiting matrix metalloproteinase activity.
- 02 Cosmetic formulations containing this extract, with a minimum of 1% (w/w) β-glucans and/or 0.10% (w/w) polyphenolics, significantly improved overall skin appearance, texture, and reduced visible signs of aging, including fine lines, wrinkles, and hyperpigmentation.
- 03 Betulin and trametenolic acid, key constituents of the extract, effectively decreased tyrosinase activity and melanin content in B16 melanoma cells, indicating potent skin-whitening potential.

Dusting Analysis
The research data does not indicate that Inonotus Obliquus Extract is commonly 'dusted' at sub-efficacious concentrations.
The Formula
Formulation
Stability
Optimal stability is achieved within a pH range of 5.0 to 8.0, with an ideal formulation pH between 6.0 and 7.0, ensuring ingredient integrity and performance.
Safety
Safety Profile
Generally considered safe for cosmetic use, with an EWG Skin Deep rating of 'LOW' for common concerns. While individuals with highly sensitive skin may experience mild reactions, studies on its polysaccharide fractions (IOPS) demonstrated non-toxicity at concentrations up to 160 μg/mL in cell models. No specific maximum concentration for the general extract in cosmetic products is established, but high dose animal studies with IOPS chromium complex (1500 mg/kg) indicated low toxicity.
