Which cosmetic surgery would you undergo?

My skin had been ravaged by acne, not just the face but also the back of my body. It is my wish to have money for the dermatologist. There was a time I was able to consult one specialist who said that I have an allergy aside from the skin disease that is infecting my skin. But I was turned off when I was given an estimated cost of the treatment, it costs an arm and a leg.
