Chin area liposuction for 15 year old? (Photo)

I have always had a bit of a double chin,it seems to run in the family. I've tried losing weight and doing facial exercises but to no avail. I'm considering liposuction for when I'm a bit older and can support the decision myself. The main reason I would like to get rid of it is because I am tired of trying to hide it in photos and not wanting to be in public in general. I am very emotionally mature and would like to start to consider now. Is this a possibility for me?
