Abstract

BACKGROUND
Research into the Baumann skin type (BST) has recently expanded, with growing interest in the development of an efficient and effective skin type classification system for better understanding of this skin condition.
OBJECTIVE
We aimed to identify male-specific skin type characteristics with investigation into the distribution of BST by age and region in the Korean male population and to determine the intrinsic and extrinsic factors related to skin type.
METHODS
A questionnaire was administered to collect information about age, region, working behavior, drinking behavior, smoking behavior, usual habit of sun protection, medical history, and the BST which consisted of four parameters; oily (O) or dry (D), sensitive (S) or resistant (R), pigmented (P) or non-pigmented (N), and wrinkled (W) or tight (T).
RESULTS
We surveyed 1,000 Korean males aged between 20 and 60 years who were divided equally by age and region. Of the total respondents, OSNW type accounted for the largest percentage and ORPW type the lowest. In terms of Baumann parameters, O type was 53.5%, S type was 56.1%, N type was 84.4% and W type was 57.5%. Several behavioral factors were found to have various relationships with the skin type.
CONCLUSION
The predominant skin type in the Korean male respondents was OSNW type, and the distribution of skin types with regards to age and region was reported to be distinct. Therefore, skin care should be customized based on detailed skin types considering the various environmental factors.

  Fig. 1 Nationwide distribution of the Baumann skin type of the 1,000 Korean males included in this study. The proportion of each skin type was described in a clockwise order. The OSNW type was the most common skin type in this study. O: oily, D: dry, S: sensitive, R: resistant, N: non-pigmented, P: pigmented, T: tight, W: wrinkled, ND: not done.

• 

  Fig. 2 Distribution of the Baumann skin type by region. There was a difference in not only the order of Baumann skin types by region, but also the diversity of reported types in each region. (A) Seoul, (B) Gyeonggi-do/Incheon, (C) Chungcheong-do, (D) Gyeongsangbuk-do, (E) Gyeongsangnam-do, (F) Jeolla-do, (G) Gangwon-do, and (H) Jeju-do. O: oily, D: dry, S: sensitive, R: resistant, N: non-pigmented, P: pigmented, T: tight, W: wrinkled.

• 

  Fig. 3 Distribution of the Baumann skin type by age. There was no obvious regular pattern in the rankings of skin type for each age group. (A) Twenties, (B) thirties, (C) forties, and (D) fifties. O: oily, D: dry, S: sensitive, R: resistant, N: non-pigmented, P: pigmented, T: tight, W: wrinkled.

• 

  Fig. 4 Distribution of the Baumann parameters. The proportion of individuals with oily, sensitive, non-pigmented, and wrinkled types were higher than that of individuals with dry, resistant, pigmented, and tight types, respectively.

  Fig. 5 Schematic diagrams illustrating the relationship between each intrinsic/extrinsic factor and the Baumann parameters. The crude analysis revealed that the parameters had different relationships with each environmental and behavioral factor (*p<0.05, **p<0.01).
