Moon Sun Young is a 29 (US age 28) year old South Korean woman, who went through an unbelievable transformation.
When Sun Young was a middle schooler, people called her "Lady", when she was in high school, people called her "Auntie", now at 29, people are calling her "Grandma". I'm sure most cases are just innocent mistakes, but that still sucks.
Sun Young lived a very rough and tiring life, without any family or much money, which is part of the reason for her old appearance (we're assuming there are biological reasons as well). She was also never able to get any dentistry done, hence her rotting teeth.
With the nickname of "Grandma in her 20's", cable program "Let Beauty" decided to give her a complete makeover and a new life. The total procedures including dentistry, were estimated to be around $100,000 USD.
Sun Young now looks fabulous, and her actual age. Although she received plastic surgery, in this case, I totally condone it. Just thinking about the amount of stress and bullying she went through her entire life - she totally deserves this!
