A Glow Up is a mental, physical, and an emotional transformation for the better. Glow Ups can be both natural or planned. As well as being gradual and permanent, or fast and temporary.

When someone hits puberty or changes from looking like a little kid to look more adult like.
Over summer Timmy had a glow up.
To go from the bottom to the top to the point of disbelief. An incredible transformation.
Wow she really did glow up. From ugly duckling to gorgeous swan!!
