double chin concerns

I am very concerned because my double chin is too prominent whether viewed from the side or the front. In particular, when I take photos, the double chin makes me look heavier than I actually am. I also have a fairly severe receding chin; is there a way to get rid of the double chin and create a sharp jawline? I’ve heard that some doctors don't recommend lifting procedures, saying that getting them at a young age can render them ineffective later on. What are your thoughts on getting lifting procedures in my early 30s? I would appreciate it if you could recommend a double chin removal procedure specifically designed to eliminate fat under the chin. Are treatments like InMode or Thermage applied to the entire face, or can they be used specifically on the double chin?
