Accroding to the whole business declining, the plastic surgery revenue dropped almost 50%. Especially on Hyaluronic Acid and Botox projects. Lots of people whose salary shrinkes but still pay attention to their appearance chose group purchasing in order to cut down the price. Famous plastic surgery specialist Dr. Chuang Chia-Rong comments on above phenomenon that group purchasing consumers still need to pay attention to the surgery quality. For example, clinics might dilute Botox with something else to make it cheaper but less effective. On the other hand, major cosmetic surgeries as bone reduction and breast augmentation had not been effected on prices because they had different consumer groups and focuses. However, in order to reward the consumers, many clinics still strengthen their service quality instead.
