The consumer's right to information is intended to protect their consent, health and safety and allow them to make informed decisions. This study aims to contribute to the eradication of the violation of the consumer’s right to information in Benin. The methodological approach adopted consisted of a review followed by field investigation with the various stakeholders, using interviews conducted from a previously established guide. The data collected has been processed by suitable statistical methods. The results revealed that of the 468 surveyed, there were 277 men and 191 women whose ages varied from 18 to over 50 years. The majority of respondents were aware of the notion of advertising. 59% of respondents bought through advertising. 70.1% said they wanted to be informed about the content of the products they buy and believed that they have the right to information. For the professionals met, the advertisement does not reveal all the informations on the products with the most convincing aim is to make the product flow more quickly. It then becomes urgent that measures be taken to avoid this imbalance between the position of consumers and that of professionals. These measures must lead to sufficient consumer protection provisions.
