Is it possible to tighten the tummy without surgery? (Photos)

Hi,I am 27 years old,I lost 40 kg(about 7 years ago) in a short time. Otherwise, I have a very thin and soft skin and strech marks. I'm keeping eye on my nutrition for some while. I've already worked RFtreatment,ultrasonic lipolysis ,lymphatic drainage ,ultrasound and mesotherapy and it did not help.I am from Serbia,and we do not have too much of a choice here. So i need your opinions can tretmans such as Tripollar or some other can help or the scalpel is only option for me?
