I think in the situation with the dove model is unethical because when you are selling stuff that are meant to enhance looks our models at all for that matter it gives off false outcomes and looks that some cannot get. Its worse when your are saying that that's how they naturally look because it is not and that is a total lie. its OK when you fix a photo or spots but only if they are suddle if you change something major that that's when it gets things mess up.
