Liposuction vs. Look Fat Injection vs. Fat Decomposition Injection

I'm currently on a diet, but I'm having trouble losing the weight on my upper arms and inner thighs.
 
It seems like if I try harder, I'll lose it, but I think if I lose more weight here,
 
I'll lose my chest fat as well... For
 
the upper arms and inner thighs,
 I'm considering
 
liposuction vs. look fat injection vs. lipolysis injection
 as the last option. 1. Fat. Advantages of suction
 : Definitely removes fat
 Disadvantages: Fear of general anesthesia, high price
 2.
 Advantages of Look Fat injection: You can go to work right away, less is removed compared to liposuction, but it can be adjusted
 Disadvantages: Is this really effective? I want to. It's hard to find proper reviews
 3. Pros of fat-dissolving injections (celebrities receive them)
 : Light and casual
 Disadvantages: Hmm, does this also work?
 Please recommend any of those 3 that have been effective.
