Why Koreans Sweat Without the Bad Smell?

12 March, 2025

Most Koreans have a rare gene variant (ABCC11) that reduces body odor by limiting apocrine sweat gland activity.

Unlike many other populations, Koreans have fewer apocrine sweat glands, which are responsible for body odor.

Koreans primarily sweat through eccrine glands, which produce odorless, watery sweat that helps cool the body.

A traditional Korean diet, rich in vegetables and fermented foods, lacks strong-smelling spices that contribute to body odor.

Frequent showers, skincare routines, and meticulous personal hygiene help keep sweat fresh and odor-free.

Because body odor is rare in Korea, deodorant use is far less common compared to Western countries.

Research has proven that up to 99% of Koreans carry the ABCC11 gene mutation, making body odor naturally rare.
