The aim of this study was to elucidate whether the thickness of the upper eyelid skin is affected by aging. The upper eyelid skins of 61 Korean women were subject to the study. Fusiform pieces of the skin, 3-mm wide, were obtained at the midpupillary line, 7 mm above the eyelashes, during blepharoplasty. The specimens were stained with hematoxylin and eosin. Thickness of the skin was measured by a micrometer under a microscope. It was substantially the same in all of the age groups. The thickness varied from 818 +/- 85 microm in subjects 60 years or older to 884 +/- 112 microm in subjects between 21-and 30-years old; the mean was 860 +/- 305 microm. Thickness of the epidermis varied from 46 +/- 6 microm in subjects between 41- and 50-years old to 52 +/- 10 microm in subjects between 31- and 40-years old; the mean was 49 +/- 9 microm. There were no significant differences among the age groups (P = 0.440). Thickness of the dermis varied from 771 +/- 78 microm in subjects older than 61 years to 834 +/- 112 microm in subjects between 21-and 30-years old; the mean was 811 +/- 117 microm. There were no significant differences between the age groups (P = 0.553). It is noticeable that upper eyelid skin thickness is not affected remarkably by aging.
本研究的目的是阐明上睑皮肤厚度是否受衰老影响。对61名韩国女性的上睑皮肤进行了研究。在眼睑成形术期间，于瞳孔中线、睫毛上方7毫米处获取宽3毫米的梭形皮肤片。标本用苏木精和伊红染色。在显微镜下用测微计测量皮肤厚度。在所有年龄组中，厚度基本相同。厚度范围从60岁及以上受试者的818±85微米到21至30岁受试者的884±112微米；平均值为860±305微米。表皮厚度范围从41至50岁受试者的46±6微米到31至40岁受试者的52±10微米；平均值为49±9微米。各年龄组之间无显著差异（P = 0.440）。真皮厚度范围从61岁以上受试者的771±78微米到21至30岁受试者的834±112微米；平均值为811±117微米。各年龄组之间无显著差异（P = 0.553）。值得注意的是，上睑皮肤厚度并未受到衰老的显著影响。
