ABSTRACT
BACKGROUND:
Methods of estimating the erythema and pigmentation reactions, such as MPE (Minimal Perceptible Erythema), ME(Minimal Erythema Dose) and MMD(Minimal Melanogenic Dose), are vulnerable to the variations of subjective visual measurements.OBJECTIVE:
By using objective and quantitative methods, the erythema and pigmentaton responses were investigated.METHODS:
A sunlight, fluorescent lamp(Waldmann UV 800) was used as a UVB light source. Multiple sites of the lower back were irradiated with an increasing dose by a constant amount, With a reflectance spectrophotometer (DermaSpectrometer(R)), erythema and melanin indices at control, MPE, MED, MMD sites were assessed. The dose-response angle of erythema and pigmentation were calculated.RESULTS:
The erythema and pigmetation indices at the control, MPE, MED and MMD sites were 8.7+/-2.0AU/30.5+/-2.6AU, 10.5+/-2.7AU/32.6+/-3.6AU, 13.2+/-3.5AU/32.6+/-3.3AU, and 10.4+/-3.0AU/ 33.5+/-2.7AU, respectively. The calculated dose-response angle accurately measured the response of skin to UVB irradiation.CONCLUSION:
In this study, use of a reflectance spectrophotometer appeared to be a more sensitive and effective method than visual assessment, in addition, dose-response angles may be an objective index for determination of skin responses to UVB irradiation.
