Rules for Consumer Endorsements

Substantiation Required

An advertisement employing endorsements by one or more consumers about the performance of an advertised product or service will be interpreted as representing that the product or service is effective for the purpose depicted in the advertisement. Therefore, the advertiser must possess and rely upon adequate substantiation, including, when appropriate, competent and reliable scientific evidence, to support such claims made through endorsements in the same manner the advertiser would be required to do if it had made the representation directly, i.e., without using endorsements. Consumer endorsements themselves are not competent and reliable scientific evidence.

Actual Consumers

Advertisements presenting endorsements by what are represented, directly or by implication, to be “actual consumers” should utilize actual consumers in both the audio and video, or clearly and conspicuously disclose that the persons in such advertisements are not actual consumers of the advertised product.


  • A brochure for a baldness treatment consists entirely of testimonials from satisfied customers who say that after using the product, they had amazing hair growth and their hair is as thick and strong as it was when they were teenagers. The advertiser must have competent and reliable scientific evidence that its product is effective in producing new hair growth.
  • An advertisement disseminated by a company that sells heat pumps presents endorsements from three individuals who state that after installing the company’s heat pump in their homes, their monthly utility bills went down by $100, $125, and $150, respectively. The ad will likely be interpreted as conveying that such savings are representative of what consumers who buy the company’s heat pump can generally expect. The advertiser does not have substantiation for that representation because, in fact, less than 20% of purchasers will save $100 or more. A disclosure such as, “Results not typical” or, “These testimonials are based on the experiences of a few people and you are not likely to have similar results” is insufficient to prevent this ad from being deceptive because consumers will still interpret the ad as conveying that the specified savings are representative of what consumers can generally expect.
  • An advertisement for a cholesterol-lowering product features an individual who claims that his serum cholesterol went down by 120 points and does not mention having made any lifestyle changes. A well-conducted clinical study shows that the product reduces the cholesterol levels of individuals with elevated cholesterol by an average of 15% and the advertisement clearly and conspicuously discloses this fact. Despite the presence of this disclosure, the advertisement would be deceptive if the advertiser does not have adequate substantiation that the product can produce the specific results claimed by the endorser (i.e., a 120-point drop in serum cholesterol without any lifestyle changes).
  • An advertisement presents the results of a poll of consumers who have used the advertiser’s cake mixes as well as their own recipes. The results purport to show that the majority believed that their families could not tell the difference between the advertised mix and their own cakes baked from scratch. Many of the consumers are actually pictured in the advertisement along with relevant, quoted portions of their statements endorsing the product. This use of the results of a poll or survey of consumers represents that this is the typical result that ordinary consumers can expect from the advertiser’s cake mix.
  • An advertisement purports to portray a “hidden camera” situation in a crowded cafeteria at breakfast time. A spokesperson for the advertiser asks a series of actual patrons of the cafeteria for their spontaneous, honest opinions of the advertiser’s recently introduced breakfast cereal. Even though the words “hidden camera” are not displayed on the screen, and even though none of the actual patrons is specifically identified during the advertisement, the net impression conveyed to consumers may well be that these are actual customers, and not actors. If actors have been employed, this fact should be clearly and conspicuously disclosed.
  • An advertisement for a recently released motion picture shows three individuals coming out of a theater, each of whom gives a positive statement about the movie. These individuals are actual consumers expressing their personal views about the movie. The advertiser does not need to have substantiation that their views are representative of the opinions that most consumers will have about the movie. Because the consumers’ statements would be understood to be the subjective opinions of only three people, this advertisement is not likely to convey a typicality message. If the motion picture studio had approached these individuals outside the theater and offered them free tickets if they would talk about the movie on camera afterwards, that arrangement should be clearly and conspicuously disclosed.
