Concerns about neck wrinkle filler nodule side effects for improving deep horizontal neck wrinkles

My facial skin is quite elastic thanks to diligent wrinkle care, but I have several distinct, deep horizontal wrinkles on my neck that make my age very obvious. It constantly bothers me and makes me feel depressed. Perhaps because I have had a habit of sleeping with a high pillow since childhood, my wrinkles tend to be deep. I am seriously considering the Maypure procedure because I heard that fillers specifically designed for neck wrinkles can smoothly fill in these lines. Since the skin on the neck is very thin and moves frequently—such as when turning the head—I am very worried about potential side effects after the injection, like the skin becoming uneven or developing nodules that feel like granules. Please let me know if it is possible to achieve a natural improvement after the procedure that would allow me to go without wearing turtlenecks.
