What it means
A glow-up is a serious upgrade, the moment someone goes from awkward to absolutely radiant. It can be looks, confidence, style or a whole life turning a corner. People post the before and after, the school photo next to the now, and let the difference do all the talking.
Usage examples
"Saw my old classmate at the reunion and honestly the glow-up was unreal, new haircut, new vibe, walked in like a different person."
"Give me a year, a gym membership and a decent skincare routine and I swear the glow-up is going to be ridiculous."
"Have you seen her glow-up since school? Total transformation, walks into the room like she owns it now."
