Investigation of symptoms of hand skin changes with aging in Korean women and development of a new standard grading scale for hand aging.

Abstract

Skin aging, particularly facial skin, has been actively studied. However, hand skin research is limited. Aging symptoms of 100 hands of Korean women aged from 20s to 60s were measured by noninvasive and bioengineering methods. Standard grade images were produced. As people got older, skin wrinkles were getting worse and skin tone was uneven with the occurrence of structural flexion. For each symptom, a suitable standard photograph of the skin of the hand was chosen and a new grading scale was made. The new grading scale developed in the present study could be employed in studies to explore aging of hand skin as one of objective indicators.
