Creative marketing or deceptive advertising?

Dr. Ad employs a variety of advertising methods to grow his practice. Two years ago, he ran an ad that said prolonged use of his $ 1,000/tube facial cream would negate a need for a facelift. Now he is facing a complaint by a patient who bought 20 tubes and saw no improvement over the course of a year. Dr. Ad claims that his marketing was harmless and no different than most other ads. Is he in trouble?
