A clinical tool used to grade changes of the skin with age and solar exposure, which is used as a surrogate marker of histological changes of photoageing.
The scale is based on deterioration in the fine reticular patterning of the epidermal stratum corneum, and ranges from Grade 1–undamaged skin with fine lines evenly spaced in 2-direction network to Grade 6–marked changes with surface flattening, deepened horizontal lines and loss of vertical lines.
In the above image, Grade 1 is in the top left corner and Grade 6 in the bottom right corner.
