Differences in skin moisturization. Studies on moisturization are inconclusive as the data are contradictory. Some authors report higher moisturization values in Asian subjects while some others report no differences between Asian and Caucasian subjects.
Eccrine, apocrine and apoeccrine sweat glands. Several papers suggest that there are differences in the number of sweat glands between different racial groups. There are few studies on sebum composition and the effect of race. One study examining Caucasians and Japanese found that like Caucasians, Japanese subjects have a greater predominance of straight chain fatty acids in their sebum wax esters than branched chain fatty acids, but the Japanese had a greater quantity of C16 isobranched chain fatty acids. Japanese men also appear to have a greater sebaceous gland activity compared with Caucasians. Nevertheless sebum levels decline with age.
