How on earth should I manage deep neck wrinkles?

Perhaps because I’ve had a habit of sleeping with a high pillow since childhood, I have two thick, deep horizontal wrinkles on my neck even though I am in my late twenties. My facial skin is still taut, but my neck makes me look ten years older, so I end up covering it with a scarf whenever I wear low-cut clothes. Even though I generously apply expensive commercial neck cream and massage it with a roller every day, the wrinkles show no signs of fading, probably because they are already so deeply etched. I heard that dermatologists offer fillers or lifting lasers specifically for the neck, but since the skin on my neck is so thin, I worry it would be extremely painful. I am also hesitant to try it because I am afraid of side effects like uneven skin texture. If anyone has actually undergone neck wrinkle treatments and seen results, I would be very grateful if you could honestly share the pros and cons.
