Is there an effective way to treat neck wrinkles that make you look older?

I used to think just taking care of my face would be enough, but one day, looking in the mirror, I became increasingly concerned about the deep horizontal lines on my neck. I don't know if it was the height of my pillow or my usual smartphone posture, but once these wrinkles appeared, they wouldn't go away with just home care. I researched neck wrinkle treatments, applied eye cream liberally, watched YouTube videos, and tried massages regularly, but they weren't enough to keep up with the rate of loss of elasticity. Now, I think I need professional help with neck wrinkle treatments, but I'm wondering which option is less irritating and more natural: filler or laser. The skin on my neck is particularly thin and sensitive, so I'm hesitant to make a decision, worried about long-lasting bruising or scarring. I'm also deeply concerned about whether directly filling the wrinkles with filler or using laser lifting treatments like Ulthera or Thermage to regenerate collagen is the safest option. I'm hoping to find the most effective solution to regain a smooth neck line without the risk of scarring.
