Certainly sub-mental liposuction (whether laser or not) would be a reasonable choice if you do not have significant amounts of skin as Dr. Seckel and Dr. Law have pointed out - however those would (at least in my opinion) fall under the "surgical" category (even though it is very minor surgery).
Non-surgical methods are decidely less effective (think those "tightening and firming" creams you see on television). The one treatment to consider that meets the "non-surgical" criteria would be something like Thermage or Cutera's Titan product. Both of those systems deliver energy to the dermis to cause some degree of tightening.
Whether this would be effective for you is debatable, but if you really, absolutely want to avoid any scar it would be something to investigate. Not trying to be too controversial - just trying to give you an answer.
I hope it helps!
