A thigh reduction procedure can vary in cost, depending upon the complexity of the procedure and exactly what is involved. A thigh reduction can be as simple as removing a small amount of excess skin from the inner thighs, to removing excess skin from around the entire circumference of the thigh and more.
If you require Liposuction to the thighs to reduce size or change the shape, the cost can range from between $5,000-$15,000, depending upon how many areas will be treated. If your problem is excess, sagging skin, this would be better treated with a Thigh Lift, which ranges between $6,000-$7,000. The best course of action is to have a consultation with a Board Certified Plastic Surgeon, and discuss all possible options based on the results of your physical exam.
