RESUMEN
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. METHODS: Literature review was used to develop a survey on current concepts relating to skin quality. The survey results were analyzed descriptively and presented to a focus group comprising five dermatologists and four aesthetic physicians. This group then discussed the concept of skin glow, how to define it and what metrics could be used to assess it. RESULTS: Surveyed practitioners (n = 38) ranked skin quality as the fourth most important factor related to a person's overall aesthetic first impression. Almost all (95%) respondents reported routinely assessing skin quality, citing serial photography (83%), and visual inspection (67%) as the main means of achieving this. The focus group defined skin glow as even reflectance from an unaffected papillary and reticular dermal collagen layer, which is created only when skin does not exhibit any characteristics that detract from this even reflectance. Due to its complexity, the focus group proposed a hierarchal framework for assessment, encompassing patient self-rating, practitioner severity rating, and supplemental use of validated measurement devices. CONCLUSIONS: Skin glow can be defined and quantified. More work is warranted to develop a practical skin glow assessment tool suitable for use in the clinic setting.
