Plastic surgery is not for the "rich and famous” exclusively. The procedures and techniques improved greatly and also became more affordable.
In the last five years there was a 304% increase in the number of cosmetic procedures. According to the American Society of Plastic Surgeons, the average household income for a cosmetic surgery patient is between $25,000- $50,000.
Affordability increased because several financial plans provide low interest payment plans to prospective patients, or they can use their credit cards (and earn airline mileage) as an acceptable form of payment for their procedures.
