Why not use foundation under eyes?

Could you elaborate on why some might question the use of foundation under the eyes? Is there a concern about potential irritation or dryness? Or is it more about the potential for creasing or caking that might detract from a flawless complexion? Additionally, are there alternative products specifically designed for the delicate under-eye area that may be more suitable? Understanding the reasoning behind this inquiry would help provide a more nuanced response.
