ELI5:What is the difference between face cream/hand cream/body cream/foot cream? Are the skin cells in those parts of the body so different from each other that they respond better to certain chemicals or is it all a marketing ploy by the cosmetic industry?

I was recently gifted a cosmetic set that had different creams for different parts of the body and I checked the ingredients to see what made them so different from each other but the ingredients are all chemical names I know nothing about. Would I be harming my skin in anyway(especially long term) if for example I used a face cream as a body cream or vice versa?

A foot cream might be a little more intense since the skin on the bottom of your feet is thicker, and thus more would be needed to penetrate all the layers.

A face cream might make sure that it doesnt leave a shiny residue after it is absorbed so it doesnt look like you have oil all over your face.

However, at their core, there is no difference between any of them expect perhaps scent. As long as your products arent some sort of "intensive care treatment", there should not be any long term affects regardless of what you use where.
