ABSTRACT
BACKGROUND:
Redness is the most common symptom among many facial dermatoses. With the rapid development of optical instruments, spectral imaging, and image processing technology, there appear varieties of skin color analysis methods and instruments. The aim of this study is to reveal the differences and correlations in measuring the facial redness between CSKIN® and VISIA® , as well as the relevance between the instrument parameters and clinical evaluation. MATERIALS &METHODS:
Forty-three Chinese patients were enrolled. Images were taken and analyzed by VISIA® from Canfield and CSKIN® from Yanyun Technology, and the facial erythema was graded by the dermatologists.RESULTS:
Feature counts within the red areas measured by VISIA® were found to have significantly positive correlations with red pixels and percent which were measured by CSKIN® on both sides of the face (r = .45 ~ .566, P < .01). The parameters analyzed by CSKIN® and VISIA® feature counts were correlated with visual scores graded by the dermatologists, VISIA® presented with a weak correlation (r = .213, P < .05), while CSKIN® had a moderate correlation with the visual scores (r = .472 ~ .492, P < .001).CONCLUSION:
CSKIN® may be another alternative option when encountering with measurement and follow-up of facial erythema.Key words
