Teenagers have a self conscious mind set when they reach a certain age. if even one person tells them a part of them is bad, they are instantly in a state of panic. The idea of an ad telling them how to get rid of acne is making them feel like it's something to be ashamed of, when it's really not. It's natural. It's a great strategy, though. Looking to an audience who easily succumb to it. But it doesn't help them feel better about their bodies or who they are. It's a win-lose situation, in my opinion. By gaining money, you are helping teenagers, and even some adults, feel like they have the wrong body and need to be different in order to be beautiful.
Ads for acne cures have a huge affect on teen body image. For teens that have acne, this makes them feel like they have to get rid of it, and when they can't it makes them insecure and upset with themselves. Ads make it seem like nobody else has it and that it's not natural. This just adds the to the stress of being 'perfect'. Usually, people in the comercials already have clear skin. So not only do teens want to get rid of their acne, they also expect to look like the people in the ads. This takes a toll on teens self esteem.
You have control over the decisions you make over the course of a day. You do not have control over catastrophes, environmental conditions, and most of the time major life changes.
