Background : The elastic properties of skin may be useful indicators of cutaneous diseases and skin aging. Objective : The purpose of this study is to obtain the normal range of skin elastic properties according to anatomical sites in normal Korean individuals and to show the differences among them. Methods : Eleven different anatomical sites were measured in 41 healthy volunteers (20 males and 21 females) with a measuring device, Dermaflex-A??. Tensile distensibility(TD), elasticity(E), and hysteresis(H) were recorded. Results : TD was decreased in the distal portions (e.g. 2.30±0.35 in the arm vs 1.62±0.30 in the palm in males) and in the sites where the subcutaneous tissue was thin (e.g. 3.08±0.60 in the abdomen vs 1.20±0.44 in the medial malleolus in males). E was also decreased in the distal portions (e.g. 82.3±8.5 in arm vs 51.2±11.1 in the palm in males) and in the sites where the subcutaneous tissue was thin (e.g. 89.3±8.3 in the abdomen vs 58.8±13.8 in the medial melleolus in males). In contrast, H had greater individual variations and it showed no definite tendency according to sites. TD and E were generally greater in males than in females, and there were some significant differences between sexes according to sites. Conclusion : Cutaneous elastic properties varied according to anatomical sites and sexes. This feature must be considered in future studies measuring elastic properties, such as aging experiments.(Korean J Dermatol 1999;37(9) : 1296∼1304)
