As in every arena of human endeavour, the field of cosmetic surgery worldwide is pockmarked with unprincipled practitioners who will "take on" any patient who comes seeking a new look. But, cosmetic surgery is not an option to be flippantly considered either by a surgeon or by a patient. It may be only skin-deep, but its implications are not.
      That is where you, as the prospective candidate, come in. If you remain a passive participant in the process, you may well end up with your mirror mocking you more than before!
So, before you permit any surgeon to adjust your physical profile, you must first adjust your psychological profile.
      To start with, explore your motivations for having the surgery. There are right reasons and wrong reasons for altering your looks with surgery.
