I've always had distinct horizontal lines on my neck, but as I get older, they've gotten deeper and can't even be covered up with makeup, so it's driving me crazy. Since I can't hide my neck and it's subtly stressful every time I look at it, I'm planning to get a proper procedure done this time. I'm scared it might turn bumpy, so I can't just go anywhere; I'm choosing really carefully. I've heard that this area depends heavily on the therapist's skill, so are there any "neck filler hotspots" that can create a natural, smooth finish without leaving visible lines?

I'm putting in a lot of effort searching online because I want to go to a place with true veteran expertise. If anyone who has had the procedure knows of a "neck filler hotspot" that does a really delicate job with the design, please share the information.
