What are these extra skin bags under my lips and how can I get rid of it? (Photos)

Hello, my lips have extra bags of skin beneath them. I tried googling to see if I could find someone experiencing the same issue, but came up with nothing, so I have provided pictures to explain the issue I am seeing with a visual aid. With my face resting I have extra tissue below my bottom lip, but it’s not extremely noticeable. However, these two extra (bag of fat I guess?) become extremely noticeable when I smile. I am wondering why my bottom lip has these bags under them and what I can do to correct this issue. Thanks in advance!
