Unless someone with a particularly large weight base goes for liposuction, the surgical effect will be more obvious.
Under normal circumstances, liposuction surgery will retain subcutaneous fat about 1CM. You should consider whether your subcutaneous fat is particularly thick, otherwise it is no different from not doing it, and you have to endure some postoperative pain, which is not worth the candle.
PS: I also use this to answer your question about that arm.
