I am curious about the procedures, effects, and side effects that can improve deep horizontal neck wrinkles.

I am looking into procedures like lasers or fillers because my neck wrinkles are deepening with age. Since the skin on the neck is thinner and more sensitive than facial skin, I am concerned about potential side effects such as prolonged bruising or uneven skin texture after the procedure. I would like to know if you have seen any improvement after receiving neck wrinkle treatments. Also, which procedure is most suitable for deep horizontal wrinkles, and how many sessions are typically required to see noticeable changes?
