In contrast, many people may buy products because of over exaggerated advertising about the goods. For example, a whitening lotion advert shows a dark skinned lady who will have more complex and white skin after using the lotion within 7 days. This advertisement leads many women to believe and buy the whitening products. However, in fact, it would take more than 7 days to get the white skin. For this reason, the consumers will buy more of the products and it will bring higher sales volumes of the lotions.
