Should I manage my weight before getting Shrink?

Recently, as my weight has been changing little by little, my facial contours also feel different than before.

I am hesitating about the order because even if I get a lift in my current state, my face shape might change again later if my weight fluctuates.

If weight changes are expected, would it be better to stabilize my lifestyle first before deciding on the procedure? I am wondering how to distinguish between skin sagging and weight changes.
