Poor skin quality can affect the success of a facelift (rhytidectomy) and neck lift to some degree. However, you can still have a facelift and you will look significantly better than if you had not received one. To improve the look of your skin after a facelift, I'd recommend concomitant laser treatments or chemical peeling to resurface and thicken the skin by stimulating the production of new collagen. Also, fat grafting can help the facelift look natural and rejuvenating. As for the neck, if your skin is very thin and you notice sagging after your necklift, you may get some relief with a nonsurgical skin-tightening treatment such as ThermiTight. All of these issues will be addressed and potential solutions discussed when you consult with a facial plastic surgeon. I hope this helps.
