Abstract

BACKGROUND
Physiological parameters of the skin measured by non-invasive methods have been considerably developed. It is known that there are some differences in physiologic parameters between different races.
OBJECTIVE
The purpose of this study is to understand the differences between the races.
METHODS
A total of 757 Mongolian participated in this study. All subjects had no major history of skin diseases requiring medical treatment. Several instruments were used such as Sebumeter, Corneometer, Mexameter for measuring sebum excretion rate, values of capacitance, melanin index and erythema index respectively. These were measured on various areas of the skin such as cheek, forehead, palm, outer arm, inner arm, back and buttock.
RESULTS
The sebum excretion rates showed higher in males than in females on the cheek and forehead in Mongolian. However, they showed higher in the females on the palm. There were good correlation between the skin sebum level and the capacitance in males and females. The melanin index and erythema index showed higher in males than in females at all sites. When we compared this with the data published in other countries, many data were similar to Korean rather than a western country's. However, the capacitance data were lower than those of Korean.
CONCLUSION
Although, this study has some limit for direct comparison between each race, our results can be used as basic data for the comparison between Mongolian and other races in the future.
