Background: Skin is considered a reflection of a person's appearance, so it is normal if many people try to take care of their skin, especially facial skin, and retard the aging process. Dermoscopy is a quick, non-invasive technique that allows physicians to observe the skin. Different ethnic groups may show different signs of aging on the face. Medan is a multiethnic city and thus might show facial skin aging differently. This study aimed to evaluate facial skin aging through the Dermoscopic Photoaging Scale (DPAS) and assess the relationship between DPAS, Glogau and Fitzpatrick scales among various ethnic groups in Medan, Indonesia.
Subjects and Methods: This cross-sectional study enrolled 155 subjects from 10 ethnicities in Medan. The examination of facial aging is based on DPAS using 11 criteria, the Glogau scale, and the Fitzpatrick skin type.
Results: Malay and Karonese got the highest DPAS score. There was a significant difference between DPAS, Glogau, and Fitzpatrick in age (p = <0.001,<0.001 and 0.032), and Fitzpatrick scores in ethnicity (p <0.001). There was a strong and significant correlation between DPAS and Glogau scores (p < 0.001, r = 0.748), while DPAS and Fitzpatrick's scores showed a moderate and significant correlation (p < 0.001, r = 0.288).
Conclusion: The highest DPAS scores were found in the Malay and Karonese ethnic groups. There were significant differences between DPAS, Glogau, and Fitzpatrick in age and Fitzpatrick scores in ethnicity. There was a strong and significant correlation between DPAS scores and the Glogau scale and a moderate and significant correlation between DPAS and Fitzpatrick scores in various ethnic groups.
