Man in the Mirror is a Michael Jackson song written by Glen Ballard and Siedah Garrett, released on his 1987 album Bad and as a single in 1988. It became one of his most recognisable ballads, known for its message of personal responsibility and change beginning with oneself. Over time, the opening has been reused widely in online edits, especially glow-up and self-improvement videos, because its gentle build mirrors a journey from reflection to action. That lasting association keeps it popular with creators today.
