Twin sisters undergo shocking transformations on Korean plastic surgery show

A pair of twin sisters suffering from severe underbites underwent drastic surgery to improve their looks.

According to a Chinese report on Sina.cn, the surgery was sponsored by Korean reality television show 'Let Me In'.

The episode featuring the twins followed their transformation from the point that they get selected to the final unveiling of their post-surgery looks.

On top of their underbites, the twins also underwent surgery to bring forward their hairline, make their eyes bigger and their faces more oval shaped.

The surgeons took great pains to make sure the twins look almost exactly the same even after surgery.

The twins told South Korean audiences that they feel more "cheerful" and "confident" after undergoing surgery.

While some say plastic surgery in this case corrected a real 'need' rather than a frivolous 'want', the reality show has previously come under fire for promoting unnecessary procedures to improve minor faults of otherwise normal looking contestants.

In addition, some worry that the programme makes people believe that cosmetic surgery is somehow simple in the course of transformation, as the show often features risky procedures such as jawline surgery, Korea Herald reported.

Jawline surgery, a procedure that shaves a square jawline to create an oval face, has become increasingly popular after some celebrities openly admitted to having it. And somewhat simpler surgeries, such as double-eyelid and nose jobs, have become so common that teenage girls drop by plastic surgeons for procedures during school breaks.

The programme vowed that it will focus on making over one's life instead of just changing their looks, but opponents claim that it drives demand for cosmetic surgery in Korea by glorifying the dramatic transformation of contestants who undergo multiple surgeries.

Some point out the show downplays contestants' problems to a matter of looks, ignoring overall society or other factors.

"Some contestants experience family separation, poverty and violence, which are mostly from social structural problems, but the show somehow blames those problems on their looks," wrote culture critic Kim.

Nothing really "cosmetic" about double-jaw surgery A radical solution to congenital facial deformities or for people unable to chew properly due to excessive over or underbite, the double-jaw surgery involves realigning the upper and lower jaws."This surgery alters your look far more dramatically than, say, Botox or a nose job because it changes your entire facial bone structure," Choi Jin-Young, a professor in dentistry at Seoul National University, told AFP.
