Some people are born with thinner lips than other people, but WE ALL develop thinning of the lips as we age. The upper lip continues to lengthen and the red lip becomes lower and less noticeable. Both lips also lose volume over time which causing the annoying “lipstick lines” causing lipstick to run.
There are a number of very effective options for lip rejuvination. See my Lip Augmentation page for more information.
