advertising: Information or manipulation?

I can't exactly say if advertising is informational or manipulative because it is dependent on many different variables. For example: what kind of advertising is it? the way a particular piece of advertisement is portrayed is based on its content and the way it is written. An "informational" advertisement would of course contain information on the particular subject that is being advertised and opinions, biased or not, are excluded completely. Manipulative advertisement would include biased opinions and deceiving factors. This can also be labeled as "false advertisement".
Example of Informational advertisement:
Smoking cigarettes can cause lung cancer.
now this is proven by fact and can't exactly be argued against. Also by saying "can" it is open and no restrictive, meaning to say it is not the ONLY cause of lung cancer and also it is not the only thing that smoking can do to you.

Example of Manipulative advertisement:
If you buy this lotion, you will look 10 years younger, guaranteed!
now this is something that people can easily give in to and is completely manipulative. It is very unlikely that a bottle of lotion can make a 20 year old look like they're 10 again.
Even if it did somewhat work, the advertisement said 10 years guaranteed, so "somewhat" isn't good enough.
