Plastic Surgery Rumor

There is no official statement about Oh! My Girl’s Hyo-jung’s plastic surgery. Choi Hyo-jung, who was born on July 28th, 1994, has the most natural look and beautiful appearance as a female idol.

If you can see closer, Oh! My Girl’s Hyo-jung’s nose is rather flat but it is an interesting proof that she has never undergone some type of plastic surgery to change and enhance her outward appearance.

Another fact that Oh! My Girl’s Hyo-jung has never gone under plastic surgery is her chubby cheeks but she has such a nice v-line on her upper face that makes her chin already stand out.

When talking about plastic surgery among K-Pop celebrities, usually it is associated with the monolid issue of their eyes. Usually, before debuting, many of them undergo plastic surgery to change the appearance of their eyelids, from monolid to double-eyelid, thus making their eyes look bigger and wider. However, in the case of Oh! My Girl’s Hyo-jung, we can see that she was born with a double-eyelid and her eyes are, in fact, another one of her charming points.

The photo below is from Oh! My Girl’s Hyo-jung’s pre-debut era and her appearance before debuting with Oh! My Girl.

And this one is Oh! My Girl’s Hyo-jung’s recent look.
