Abstract

BACKGROUND
Pores are the openings of the pilosebaceous unit or the apocrine gland. Increase in pore size or in the number of dilated pores may be a cosmetic problem. To date, epidemiological studies on the numbers of dilated pores have been rarely reported.
OBJECTIVE
To analyze the distribution of pores and the factors affecting pores.
METHODS
We compared the number of dilated facial pores on the face according to site, age group, and sex. The relations of pore counts to wrinkle severity and to the amount of hydration were also analyzed. Dermavision(TM), a device that can take cross-polarization, parallel polarization, and ultraviolet light images, was used. Parameters were measured at three points: the forehead, cheek, and nose.
RESULTS
The results revealed that dilated pores were more common on the nose and forehead. The pore counts were increased with age, and the increment was significant between participants in their 30s and 40s. Moreover, dilated pore counts were affected by wrinkle severity. The amount of hydration did not affect the counts of dilated pores.
CONCLUSION
In this study, the number of dilated pores differed depending on the location. Moreover, it was confirmed that pore counts were higher in older persons. The pore counts showed a correlation with wrinkle severity.
