The purpose of this study was to examine the influence of major variables and their relationship with the males` appearance consciousness that affect the men`s cosmetic consumption. Also, the study also intended to verify the differences of men`s cosmetic consumption between Chinese and Thai males. The samples consisted of 200 males who ranged in age from 18 to 35 years (M=24.64). One hundred participants were Thai and one hundred were Chinese. Based on literature review, six research questions were proposed. For data analysis, descriptive statistics, factor analysis, t-test, and multiple regression were used for this study. As the results, the sociocultural attitudes of consumers towards their appearance are positively relevant to the self-esteem and public self consciousness. Also, appearance consciousness such as appearance evaluation and appearance orientation led more cosmetic consumption. Chinese males revealed higher scores on public self-consciousness, appearance orientation, and sociocultural attitudes toward appearance than Thai males. Based on these results, some implications for global cosmetic markets would be suggested.
