Gloeostereum incarnatum is an edible and medicinal mushroom belongs to Family Cyphellaceae of Polyporales, Basidiomycota. The purpose of this study was to investigate the free radical scavenging, anti-inflammatory, and melanin synthesis inhibitory activities of fruiting bodies of Gloeostereum incarnatum. In the free radical scavenging activities, the mushroom extracts showed good 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging and chelating activity on the ferrous ions compared with the positive control, BHT. The mushroom extract suppressed nitric oxide (NO) production in LPS-induced RAW 264.7 macrophage cells in dose dependant manners. Significant reduction of paw edema of rats were observed at 2~6 h after administration with 50 mg/kg of the methanol and hot-water extracts, which were comparable with treatment of 5 mg/kg of indomethacin, the positive control. The melanin synthesis of Melanoma B16/F10 cells treated with $100{\mu}g/mL$ of the methanol and hot water extracts decreased melanin concentration to 50% and 45% compared with the control, arbutin. Therefore, the experimental results showed that methanol and hot-water extracts of Gloeostereum incarnatum fruiting bodies might be used for good sources of anti-inflammatory, free radical scavenging, and skin whitening agents for human health.

In the questionnaire about how often the subjects who used skin lotion experienced skin irritation, $100{\%}$ of the subjects replied there was no skin irritation. 8. the subjects who used Korean herbal cosmetics showed significant result in the questionnaire about how much moisture they feel when using cream. 9. The subjects who used neutral & dry cosmetics showed more significant result than the placebo group in the questionnaire about if the cosmetics spread well when using emulsion. 10. The subjects who used oily & combinational cosmetics showed more significant result than the placebo group in the questionnaire about how much moisture they feel when using cosmetics. 11. In the questionnaire about how they feel when using cream $13{\%}$ of all the subjects replied "very good", $49{\%}$ "good", and $2{\%}$ "so so". 12. In the questionnaire about how often the subjects who used cream lotion experienced skin irritation, $96{\%}$ of the subjects replied there was no skin irritation. 13. In the measurement of coreometer, the subjects who used oily & combinational cosmetics showed significant result(measurement area : indang). Especially in the area of sungjang there is significant difference between the subjects group and placebo group. 14. In the measurement of skin-ph-meter, there was no significant change in all group. 15. in the measurement of melanin-erythema index meter, the subjects who used cosmetics which doesn't contain Korean herbs showed significant change and made significant difference in comparison to the subjects who used Korean herbal cosmetics.
