anatomical changes of the face which effect the lower face and lips here are some examples:
The teeth retrude, which shows in the area around our jaw lines.
Our layers of fat move and change leading to nasolabial folds – the lines from the corner of your nose to the sides of your mouth
We lose fat, and/it moves to lower
Our bones age and deteriorate too, which then impacts how all the other tissues – muscles, fat and skin can sit on top.
