60 & neck skin laxity & platysmal bands after deep plane facelift 6 months ago - is there a solution? (Photos)

I am 60 years old and had a deep plane facelift in March. When I am on video calls, I notice that I still have skin laxity and visible platysmal bands when I am talking or swallowing. If I am not moving, then my neck looks fine except of the horizontal lines that I intend to get treated with filler. Is there a solution for this or is this just normal result?
