This research is to verify the relationships between factors that influence consuming behavior practice through a model structure by setting perception of DIY cosmetics, environmental awareness, and good life-style as causing factors. A survey is conducted among women of nineteen or older, who are major consumers of cosmetics. The research specifies the relations that all factors are led to consuming behavior practice by analyzing complexly, not by explaining fragmentary factors.
?A survey is conducted among seven hundred and thirty DIY cosmetic users residing in Daegu or Gyeongbuk, and AMOS 22.0 program is used for the analysis

To make an experimentally approach on the study, to analyze the traits of surveyees, and to verify the structural relationships between perception of DIY cosmetics, environmental awareness, good life-style and consuming behavior practice, following questionnaires are previously set-up.
1) Are perception of DIY cosmetics, environmental awareness, and good life-style going to be directly influential to consuming behavior practice?
2) Are perception of DIY cosmetics and environmental awareness going to be directly influential to good life-style?
3) Is perception of DIY cosmetics going to be directly influential to environmental awareness?
4) Is perception of DIY cosmetics going to be indirectly influential to consuming behavior practice through environmental awareness?
5) Is perception of DIY cosmetics going to be indirectly influential to good life-style through environmental awareness?
6) Is perception of DIY cosmetics going to be indirectly influential to consuming behavior practice through good life-style?
7) Is environmental awareness going to be indirectly influential to consuming behavior practice through good life-style?

The Findings are as follows;
First, after setting up a hypothesis that perception of DIY cosmetics, environmental awareness and good life-style directly influence consuming behavior practice, a verification of the hypothesis is performed, and the survey proves that the hypothesis is true. According to the survey, consuming behavior index is high when DIY cosmetics, environmental awareness and good life-style are high; environmental awareness(.36) is relatively more influential than perception of DIY cosmetics(.18) and good life-style(.27). The result suggests that the society should aim for environmental awareness which is highly conscious of the need to protect the environment and good life-style, which emphasize on saving resources and protection of environment.
Second, in a careful verification of another hypothesis that perception of DIY cosmetics and environmental awareness directly influence good life-style, perception of DIY cosmetics and environmental awareness influence good life-style, and perception of DIY cosmetics(.13) has more leverage than environmental awareness(.75). This implies that environmental awareness should be encouraged in order to implement good life-style.
Third, another hypothesis that perception of DIY cosmetics directly influences environmental awareness comes out to be true under the statistical verification. According to the survey, higher environmental awareness index is followed by higher perception of DIY cosmetics index, which means perception of DIY cosmetics leads to environmental awareness.
Fourth, developing a hypothesis that perception of DIY cosmetics indirectly has an effect on consuming behavior practice and conducting a statistical test on the hypothesis with existing data, the conclusion satisfies the hypothesis. This suggests that positive perception of DIY cosmetics positively affects environmental awareness so that perception of DIY cosmetics can promote consuming behavior practice.
Fifth, another research is conducted assuming perception of DIY cosmetics affects indirectly to good life-style, and the assumption is found to be true. This means that acknowledging DIY cosmetics as more attractive and contributing to the environment has an impact on both environmental interest and recognition of its significance, and this affects good life-style which supports saving natural resources and protection of the environment.
Sixth, the fact that perception of DIY cosmetics indirectly influences consuming behavior practice is concluded through a statistical verification with existing data on the assumption that Perception of DIY Cosmetics is effective in consuming behavior practice indirectly.
Finally, the assumption that environmental awareness has indirect effect on consuming behavior practice is tested and proved to be true, which means the higher environmental awareness a consumer has, the consuming behavior practice will be.

Results above suggest that perception of DIY cosmetics, environmental awareness and good life-style are important for consuming behavior practice.
In consequences, the way that promotes consuming behavior practice of DIY cosmetics consumers is to promote perception of the product, environmental awareness and awareness of reuse as well as public environmental awareness, individual environmental awareness and ethical consumerism.
