CP2 you may be describing lipomas. The gold standard treatment for these is excision. Other treatment modalities include intralesional steroid injections or injectable lipolysis. There now these non invasive ultrasound devices which can be tried.
Fortunately there are many non-surgical alternatives to going under the knife in order to tighten lax skin. Infrared devices such as the Sciton's SkinTyte, Cutera's Titan and the monopolar radiofrequency device Thermage can be used. Your dermatologist should be able to explain to you what to expect and the differences between these procedures and the surgical alternative. The CO2 laser being a hot laser also delivers some thermal injury responsible for some tightening.
