Curious if there is a best way or a difference to which product you use first when lip filler layering?

Hello, I have heard that if you are going to layer filler, many injectors use a more defining filler first (Restylane Defyne) to add height & definition, and a softer filler at a second visit to add volume and hydration (ie: Restylane kysse or versa). If you have the versa or kysse injected first, can you add height & definition at the second visit with Defyne, or is it best to not layer it in this order? Curious if there is a best way or a difference to which product you use first. Thank you.
