Why can’t I find many people who’ve made videos with information about their experience with permalip lip implants?

why does it seem like you can find people with stories and video experience getting lip fillers anywhere but it’s hard to find to many people with videos or info explaining their experience getting a permalip implant? Why does it seem like permalip is less popular even though it’s basically a permanent alternative to filler? This concerns me because I’d like the lip implant simply because it’s like permanent filler but I don’t see all that much information on it which is a bit concerning.
