An absence of imperfections: A proposed framework for defining, assessing, and achieving skin glow.

Background: Skin glow is a subcomponent of skin quality. It has become entrenched in the cosmeceuticals and aesthetics lexicons as a synonym for health and youth, but is not well-defined as a scientific metric.

Aims: To examine the concept of skin glow and determine if it is an objective concept that can be defined and quantified.
