Lipstick is a song by Orange Caramel, the three-member sub-unit of South Korean girl group After School, released in 2012 as the title track of their first full album. The group built a reputation for bright, quirky concepts that stood out from darker K-pop trends of the time, and Lipstick became one of their signature tracks. It later found a second life online, where fans shared the chorus in makeup videos, dance covers and throwback edits. Its cheerful melody and distinctive styling keep it recognisable to K-pop fans more than a decade later.
