Construction method of ultraviolet-induced skin blackening model

The invention discloses a construction method of an ultraviolet-induced skin blackening model. The construction method comprises the following steps: irradiating a marked area of the skin of a healthy to-be-tested object by utilizing a blackening principle of a blackening lamp, irradiating once every 48 hours within two weeks, inducing skin pigmentation at the marked position, and then testing the MI value, L * value and ITA degree of the skin of the tested object. The method has the beneficial effects that the cost of test equipment is greatly reduced, the problem of sunburn in the process of determining the minimum erythema amount is solved, the method is not required to be supervised by dermatologists, and the effect of inducing skin blackening by ultraviolet rays can be achieved. 本发明公开了一种紫外线诱导皮肤黑化模型的构建方法；包括如下步骤：利用美黑灯美黑的原理，照射健康待测对象皮肤的标记区域，2周内每48h照射一次，诱导标记处皮肤色素沉着，继而测试受试对象皮肤MI值、L*值和ITA°。本发明的有益效果如下：极大的降低了测试设备成本，解决了在确定最小红斑量的过程中出现晒伤的问题，不需要在皮肤科医生监督下进行，同时又可以达到紫外线诱导皮肤黑化效果。
