The research is proposed to study the effects of the huge amount investment by body-shaping advertising on the body images of teenagers. The research has found there are significant relationships between advertising investment and information awareness， the information awareness and degree of agreement of the advertising appeals， the agreement of advertising appeals and the degree of frustration and anxiety of being criticized by peer groups and willingness to do the body-shaping.
This research also found that the exposure to critical discourses of body-shaping industry is not high. Meanwhile, the exposure has not exerted significant influence on the willingness to do the body-shaping. Part of the reason is probably because of the overwhelming social pressure constructed by the media advertisement. However, further research needs to be conducted to explore what is more effective strategy to deconstruct the advertising effect.
