Does the speed at which my skin improves vary by area after receiving Density?

I am looking into getting Density for the first time.

My face has lost elasticity overall.
I am particularly concerned about the corners of my mouth compared to other areas.

Whether it changes to something similar all at once overall
Or I am curious if the timing of the changes varies depending on the area, such as the cheeks or jawline.

Rather than judging immediately after receiving it once
I would also like to know if it is right to take some time to see.
