Television skin commercials

TV commercials are extremely educational but not for the reasons you think.  Camera and lighting are the name of the game.  You know the  double  identical lady where one is skinny and one is plumb?  I don't for a minute think those are two pictures of the lady taken at a different times.  I've seen this happen too many times to know its camera trickery.  My other favorites are different ladies who get the 'magical' youth creme applied to half their face.  After the applications, do you notice the ever so gradual change in lighting?  As the untreated side gets darker, the wrinkles appear just that, more wrinkled.  Then switch to the lighter side of the face.  The 'treated' side.  My my.  What an improvement.  Just a little more light lessens the appearance of the aging wrinkles.  Commercials (some are funny) but more often that not, they're extremely educational.  Pay attention.  Don't waste you money...................................marge
