I would like to inquire about body lifting treatment!

I've been struggling with areas that don't gain elasticity easily, like my arms and abdomen, even though I've recently started working out, so I'm looking into body lifting and seeking professional help.
I'm curious as to how the procedure is performed.

The thing I'm most curious about is how much pain is there and how long does it take during the actual procedure?
I'd like to know what popular body lifting procedures are available for beginners like me without worrying about side effects, and what the post-procedure care is like. Could you please suggest a body lifting procedure that's right for my abdomen?
Please reply!
