DETECTION METHOD AND DETECTION DEVICE FOR INDIVIDUAL MINIMAL ERYTHEMA DOSE

摘要

Disclosed are a detection method and a detection device (1) for an individual minimal erythema dose. The detection method comprises the steps of: detecting the chromaticity of the skin color of an individual (S10); obtaining a preset minimal erythema dose and a preset erythema generation value according to the chromaticity of the skin color (S20); obtaining a dose value of an ultraviolet source (S30); detecting the degree of ruddiness of a skin block (2) of the individual for the first time, and obtaining a first ruddiness value (S40); covering the skin block (2) with an ultraviolet-absorbing compound having a sun protection factor (S50); detecting the degree of ruddiness of the skin block (2) of the individual for the second time after the skin block (2) receives irradiation from the ultraviolet source, and obtaining a second ruddiness value (S60); obtaining a time value if the difference between the second ruddiness value and the first ruddiness value is greater than or equal to the preset erythema generation value, the time value being the time interval between the first detection and the second detection (S70); and obtaining the individual minimal erythema dose according to the dose value, the sun protection factor and the time value (S80). The detection method and the detection device can obtain the actual ultraviolet dose that the individual's skin can withstand by correcting the individual minimal erythema dose.
