Is surgery the only answer to getting rid of a double chin?

hello.
I used to have almost no double chin, but as I've gotten older, I've started to notice that I have a double chin even when I look down. Whenever I take pictures or my husband tells me to look at my double chin, I get even more self-conscious and annoyed.^^;;

It looks different from different angles, but my jawline definitely feels less elastic than it used to. They say sagging skin due to gravity is inevitable as you age, but... I'm wondering if getting rid of a double chin is really that difficult.

Has anyone tried any treatment to get rid of their double chin? While home remedies are great, if you want quick results, I'd like to know if treatment is the only option. If so, which treatments are most effective, and if so, what types of treatments are helpful for eliminating a double chin, that would be incredibly helpful!
