Thirty female volunteers with age between 20 and 45 years old were kindly invited to use the cosmetic product on the inner side of their crank arm for a testing period of 8 weeks continuously. Values of Ml, L* and ITA° of the skin were measured and the results display significant difference(P < 0. 05) before and after the 8 weeks testing period. Duncan multiple comparisons showed that the whitening efficacy of cosmetic product formulated with the extract from Tricholoma matsutake Sing is significantly greater than that of the formulation matrix and equivalent with that of ascorbyl ethyl ether. Via the data collection and statistical analysis, this method can directly reflect the whitening effect of active additives in cosmetics, and it is suitable for the evaluation of the whitening efficacy of cosmetics with additives.展开更多
