It is a total false information about Plastic Surgery lasting a certain time. The time a result will last, depends on age, stability on weight, genetics, quality of tissues, nutritional status, physical activity, areas of the body. It is never the same how much time it will last a surgery on a 30 YO in comparison with a 70 YO, or a healthy person in comparison with a diabetic or an after massive weight loss patient, it will never last the same in some one who gain and lose weight constantly or someone who’s stable through exercise and healthy habits of eating. It will not last the same time a surgery in Asians vs Caucasian. Or someone active VS sedentary. Also surgical technics give different lasting results: mini faceliftmini resultsmini time lasting. If you are young, no illnesses, weight stable, do exercise, have healthy habits, don’t smoke, most likely an arm lift will be nice and tight 2-3 years and then the skin will start giving. If your degree of saggy skin is severe it will never go back to that. Nice results will last 7-10 years. Back lift is pretty stable all years. Just consider we are aging every day. Be encouraged!
