Migration is extremely rare when done correctly by a qualified professional. It's one of those things that gets blown up on the internet through exaggerated stories, but in reality it's not something most people experience. The technique matters so much here, which is why working with someone experienced is crucial. If someone has had migration issues, it's usually because the injector didn't place the product correctly or didn't use the right technique for their face shape. The product itself doesn't just wander around on its own, it stays where it's placed when injected properly.
