Clearasil?

Personally I think that all acne ads are kind of funny in the way that they are all the same.  They all guarantee fast results, but in reality most do not work that way.  They all try to compete to get the best results and especially with this ad it is trying to tell teenagers that this "new formula" makes your pimples go away in four hours.  Easily teenagers fall for this because most of the time they don't know if it will work until they try it.  

In this ad there is a lot of vagueness going on because they don't explain how or show any before and after shots.  For all we know they could have just gotten a picture off the internet and just touched up his face making it look like he has no pimples.  Therefore proving that this product works really well, making you have clear skin.  

Throughout this ad the advertising techniques used are weasel words, plain folks, simple solutions, and repetition.

The phrase that represents weasel words is "as little as."  This says that it will take four hours to make your pimple reduce in size but it could take longer.  I see it as the minimum time for reduced pimple size.  

Plain folks is here because, although it doesn't name a price, it is not very expensive and anyone can buy it.

Simple solutions is used; "visibly reduces...as little as four hours."  It is saying, buy this and your pimple will soon be gone.  

Repetition is used quite a bit only to advertise the number of hours it takes for your pimple to be smaller in size.  They use the number four, three times and a clock just to emphasize it even more.  

The needs used in this ad are the need for attention and the need to satisfy curiosity.  

The need for attention is really obvious because this a product that helps "make you look better."  When someone has pimples they obviously don't want to show them off but if they were to use this then they wouldn't have to hide there pimples and be the "center" of attention.

The need to satisfy curiosity is here because teenagers don't know if the product will work well unless if they try it out for themselves, and see if it really works in four hours.
