Skin booster for lips. Would this treatment help fill out lip lines

I am happy with the shape and size of my lips now but after having dissolved them they still have some wrinkles in them even after refilling. I don’t want to refill again as I’m happy with the size, so my injector suggested an “injectable hyaluronic acid lip balm”. She said the hyaluronic acid used is thinner and not cross linked so it adds hydration but not volume. I’ve never heard of this treatment before. Would this treatment help fill out lip lines? Or not make much difference?
