Abstract

BACKGROUND/PURPOSE: The assessment of the sensitivity of human skin to ultraviolet (UV) radiation is important in the area of phototherapy, photodermatoses, photo-aging, photo-carcinogenesis, and photo-protection. Some reports have shown that quantitatively measured skin color is a good indicator for predicting UV sensitivity to human skin in Caucasians. In this study, our aim was to define the correlation between skin color and the skin phototype assessed by the Fitzpatrick method in Asian brown skin.

METHODS

A total of 180 medical students with similar life styles were included in this study. Their skin phototype was classified according to the system introduced by Fitzpatrick. Then, using a Minolta Spectrophotometer CM-2002, their skin color was determined on the buttocks and forehead. The buttock color was taken as the constitutive skin color, and the forehead color as the facultative skin color. Using these measured values, we compared the skin color with the skin phototype to find their correlation. Also, we investigated whether the difference between the constitutive and facultative skin colors of each individual had a relationship with his or her skin phototype.

RESULTS

The constitutive skin color became darker with increasing skin phototype, and this change was statistically significant. As for the facultative skin color, it also became darker with increasing skin phototype, but was less well correlated with the skin phototype than the constitutive skin color. However, the difference between the constitutive and facultative skin colors did not show consistent results in predicting the skin phototype.

CONCLUSION

In this study, we found that the constitutive skin color can be a good indicator of the skin phototype. However, the difference between the constitutive and facultative skin colors of each individual does not give any meaningful information for the assessment of his or her skin phototype in Asian skin.

摘要

背景/目的：在光疗、光皮肤病、光老化、光致癌作用及光防护领域，评估人体皮肤对紫外线（UV）辐射的敏感性至关重要。一些报告表明，定量测量的肤色是预测白种人皮肤对紫外线敏感性的良好指标。在本研究中，我们的目的是确定亚洲棕色皮肤中肤色与通过菲茨帕特里克方法评估的皮肤光类型之间的相关性。

方法

本研究共纳入180名生活方式相似的医学生。根据菲茨帕特里克介绍的系统对他们的皮肤光类型进行分类。然后，使用美能达分光光度计CM - 2002在他们的臀部和前额测定肤色。将臀部颜色作为固有肤色，前额颜色作为应变肤色。利用这些测量值，我们将肤色与皮肤光类型进行比较以找出它们的相关性。此外，我们还研究了每个个体的固有肤色与应变肤色之间的差异是否与其皮肤光类型有关。
