What can I do about my wrinkly and saggy neck, should I get neck lift combined with a facelift?

Hello, I am 54 yo. I have recently gotten slammed with wrinkles. I have been blessed with a real good square jaw so for now I'm not sure I am ready for a facelift as my face isn't dropping too much. But my neck started looking bad once I turned 50. real loose skin and crepey. I haven't taken the best care of my skin but not the worse either. But have admittedly been real bad about keeping a straight posture. Anyway, someone told me that neck lifts are usually performed with a face lift. is That true.
