In this treatise, a survey was conducted on American female consumers to confirm the possibility of segmenting the American cosmetic industry by classifying lifestyles and analysing differences in consumer behavior, and also to provide global marketing strategy for entry into the American cosmetics industry by Korean companies. The results of the analysis provided three categories of American female consumer lifestyles. The first is the "practical conservative" type(58 people) who are fairly indifferent to or uninterested in external changes. The second is the "pro-active sensitive" type(48 people) who are interested in external changes and want to live a leading life. The last is the "neutral economical" type(54 people) who resemble characteristics that are in between the previous two types. The study has showed there was a difference in consumer motivation, considerations during selection, factors associated with shop choice according to consumer classification. It provides evidence that lifestyles can be a criteria in segmenting the American cosmetics market.
