RM, Jin, Suga, J-Hope, Jimin, V, and Jungkook look flawless all the time. And because of that, it’s quite easy to be envious of their beautiful hair and perfect skin.

But even though they always look amazing, BTS also has some flaws that they struggle with. As for Jungkook, he had a problem with acne and acne scars, especially on his right side.

Some ARMYs who had the chance to meet BTS in person commented that Jungkook’s skin problems become visible when his makeup melts during their performances. This is just a reminder that even superstars have skin issues, too.

Being an idol, Jungkook’s skin may have become more sensitive because of all the thick make-ups that they have to use during tours, appearances, promotions, etc. So what did the golden maknae do to cure his acne? The BTS members reveal his skincare secret during interviews.

When the show's MC asked, “Which member takes the most care of his skin?” the rest of the BTS boys pointed at Jungkook. That’s when Jin revealed that JK always had vinegar on his dressing table.

In a different interview, RM asked Jungkook why did he always bring vinegar with him? J-Hope even complained about the stinky smell in their car. Jungkook then said that he was using vinegar for skincare. He explained that he washed his face with water and added a few drops of vinegar.

It is worth noting that Jungkook was using apple cider vinegar for his skincare and not some ordinary vinegar. ACV is known for preventing acne and pimples, which Jungkook was suffering from.

On the online forum Quora, one fan asked: “Did Jungkook clear his acne by using apple cider vinegar?” ARMYs then discussed the BTS star’s skincare routine.

“Yes, Jungkook has used apple cider vinegar to clear his acne. According to the other BTS members in a radio show, Jungkook carries or used to carry apple cider vinegar in his bag every time they went out,” one wrote. “Yes, he did. It may seem odd, but back when BTS, especially Jungkook, was receiving backlash for not having clear skin, Jungkook used this method,” another one commented.

A fan also shared that BTS uses “pimple patches” to reduce the bumps, pain, and redness of the acne. “They also use ‘pimple patches’ reference Bon Voyage season 3 in Malta where Jhope asks if anyone brought some with them and Jimin had some in his suitcase,” they said.

It should also be pointed out that BTS certainly does skin treatments, facials, and other beauty regimens. So although Jungkook attests to the effectiveness of ACV, he's receiving other treatments as well.
