[摘要]目的：观察年龄和季节对唇部干燥度和老化的影响。方法：将56名年龄20～50岁的成都地区女性在签署知情同意书后入组，分为高、低年龄组，分别在秋、冬、春、夏四季节观察唇红部皮肤的干燥度、细纹、鳞屑、皲裂、弹性、饱满度及光泽度。结果：两年龄组唇红部干燥度、细纹、鳞屑有显著差别(P<0.05)，高龄组比低龄组严重；弹性和光泽度低龄组显著好于高龄组(P<0.05)；皲裂、饱满度两年龄组无差别(P>0.05)。低龄组唇部皮肤的干燥度、细纹、鳞屑及弹性评分均随着季节而改变(P<0.05)，高龄组唇部皮肤的临床评价，干燥度、鳞屑、皲裂及饱满度评分均随着季节而改变(P<0.05)。两组均在冬季最为严重。结论：本研究提示不同季节、不同年龄的唇部干燥、唇部老化参数会发生改变，图谱法在唇部临床评价中是可行的。

Abstract: Objective To observe age and seasonal effect on the lip physiological condition, such as dryness and aging. Methods 56 healthy female volunteers, aged 20～50, were recruited in Chengdu after signing informed consent form. They were split into two matched age groups: younger group included 27 women 20～35 y.o; older group included 28 women 36-50 y.o. The vermilion border of lip was assessed by clinical evaluation over the sequential four seasons. Evaluation parameters included overall dryness, fine lines, flakiness, chapping, elasticity, plumping and gloss. Results There were significant differences between the two age groups in clinical grading scores of overall dryness, fine lines, flakiness(P<0.05): the scores were higher in the older group. Elasticity and gloss were better in the younger group whereas chapping and plumping showed no significant difference (P>0.05) between the two age groups. In the younger age group, lip skin dryness, fine lines, flakiness and elasticity scores changed with the seasons (P<0.05). In the older age group, lip dryness, flakiness, chapping and plumping scores changed with the seasons (P<0.05). The most severe condition was observed in winter in both groups. Conclusion This study indicated that lip dryness and lip aging parameters would alter with seasons and age. Lip dryness atlas may be a useful way for clinical evaluation of labial skin.
