Is removing fatty deposits under the eyes—which cause embarrassment and make a person look older—with a simple surgical procedure considered forbidden cosmetic surgery?

It is permissible to remove fatty cysts around the eyes if they affect vision or eye movement, or cause a noticeable disfigurement that is out of the ordinary. This falls under the category of permissible medical treatment or lawful beautification. However, if they do not significantly affect vision or appearance, it is not permissible to remove them.
