Not all celebrities are born good-looking, but these 10 Korean male stars have worked hard to shed their awkward looks and blossomed into the handsome heartthrobs that they are today.
According to Allkpop.com, idols like B1A4's Sandeul and B2ST's Doojoon hid behind their glasses when they were teenagers.
It is hard to image by looking at their younger photos that these geeky teens could be highly-sought after celebrities when they are older.
Some of them also carried extra weight like Big Bang's T.O.P, 2AM's Changmin, and even EXO-M's Xiumin in the past, sporting chubby cheeks and round tummies in their school photos.
With all the dancing they do for their performances these days, these boy band members can keep the weight off easily.
Some of these male stars might have been born with good features, but not all of have a natural fashion sense.
The glamorous looks that we see today were achieved after years of experimentation with hilarious fashion faux pas.
