Using Dish Liquid On Greasy Skin
On paper, it makes sense. If dish liquid can break through the greasiest of pots and pans, then it can tackle your oily T-zone. But your skin is sensitive, and it can't handle the type of stripping chemicals you put on your stainless steel pots. 

It will tear away the natural oils your skin needs to stay healthy, and it will cause your face to get uncomfortably dry — which will only trigger your skin to create more oil!
