Double Chin Exercises

Can these stretches/exercises potentially cause sagging skin or wrinkles from stretching and holding your face in an expression? If not, can you explain why? I ask this because I already suffer from the aforementioned and I am really hoping this is not the case because I do not wish to opt for corrective surgery.

Some of the exercises require unnatural poses e.g. pulling your lower lip on your upper one for the double chin stretch. Your help and honesty will be greatly appreciated. Thank you so much in advance!

By the way: I am Caucasian if that is any help in answering my question (because of our skin aging).
