Have you ever wondered why South Koreans seem almost immune to the worries of body odor? While people around the world battle with deodorants and antiperspirants, South Koreans enjoy a unique freedom from this common concern. What’s their secret?
Dive into the intriguing blend of genetics and culture that keeps body odor at bay for South Koreans, and discover how this fascinating phenomenon sets them apart.
Scientific Studies and Findings about Korean secret
Bristol University Study
Research by the University of Bristol highlighted the influence of the ABCC11 gene on body odor. In a study involving 6,495 participants, it was discovered that the ABCC11 gene variant significantly reduced the activity of apocrine glands. This finding was particularly evident among East Asians, including South Koreans, who were found to have a high prevalence of the gene variant.
The Science of Sweat and Bacteria
Understanding why the ABCC11 gene affects body odor involves exploring the interaction between sweat and bacteria. When we sweat, it’s not just water being released; our sweat contains salts, proteins, and other compounds. Body odor arises when bacteria on our skin break down these compounds, releasing smelly substances in the process.
The ABCC11 Gene and Its Role
Understanding the ABCC11 Gene
One key factor contributing to the lesser body odor in South Koreans is the presence of the ABCC11 gene. This gene determines the type of sweat our bodies produce, affecting body odor. Human sweat glands are divided into two main types: eccrine and apocrine. Eccrine glands produce a watery, odorless sweat, while apocrine glands secrete a thicker, more odorous substance.
Variants of the ABCC11 Gene
The ABCC11 gene exists in different variants, significantly impacting the activity of apocrine glands. A specific variant, predominantly found in East Asians, reduces the production of smelly sweat by limiting the activity of these glands. Studies show that around 80-95% of Koreans carry this variant, contributing to their reduced body odor.
The Role of Sweat Glands and Bacterial Activity
Types of Sweat Glands
The apocrine glands, primarily located in areas like the armpits and groin, produce sweat that contains more proteins and lipids. These compounds provide a rich environment for bacteria, leading to a stronger odor. However, individuals with the ABCC11 gene variant have less active apocrine glands, resulting in less of the sweat that causes body odor.
Bacterial Activity
The interaction between sweat and bacteria is crucial in understanding body odor. Bacteria metabolize the compounds in sweat, producing malodorous byproducts. Since the ABCC11 gene variant limits the secretion of protein-rich sweat, there is less material for bacteria to break down, thereby reducing body odor.
Population Data and Gene Distribution
East Asians and the ABCC11 Gene
Several studies have underscored the strong correlation between the ABCC11 gene variant and East Asian populations. Research published in the Journal of Investigative Dermatology shows that around 80-95% of Koreans possess the ABCC11 gene variant. This is in stark contrast to European and African populations, where the prevalence of this gene variant is much lower, at approximately 2-3%.
Global Distribution of the ABCC11 Gene
The distribution of the ABCC11 gene variant provides insight into differences in body odor among various populations. In East Asia, the high prevalence of this gene variant results in reduced body odor. Conversely, in regions like Europe and Africa, where the gene variant is rare, body odor tends to be more pronounced.
Cultural Practices Enhancing Genetic Advantages
Hygiene Habits
In South Korea, maintaining personal cleanliness is deeply ingrained in the culture. Regular bathing, meticulous grooming, and the use of hygiene products are routine activities that help reduce body odor. These practices, combined with the genetic advantage provided by the ABCC11 gene variant, create a powerful combination that minimizes body odor.
Dietary Influences
Diet also plays a role in body odor. South Koreans’ diets are typically rich in vegetables, rice, and fish, which are less likely to produce strong body odor compared to diets high in red meat and dairy products. This dietary preference further complements the genetic factors, contributing to the overall reduction in body odor.

Personal Accounts and Anecdotal Evidence
Expat Experiences
Numerous personal accounts from expatriates and tourists support the scientific findings regarding body odor in South Koreans. Many foreigners living in South Korea have noted the minimal use of deodorants and the lack of body odor compared to their home countries. Expats often report their surprise at the scarcity of deodorant products in stores, aligning with the genetic data suggesting a lower need for deodorant in these populations.
Cultural Perceptions
Cultural perceptions also play a role in managing body odor. In South Korea, there is a cultural aversion to strong body odor, reinforcing the importance of personal hygiene. This societal norm ensures that even those with mild body odor take measures to maintain freshness, contributing to the overall perception of reduced body odor in these populations.
Conclusion: Embracing the Genetic Gift
The reduced body odor among South Koreans is a fascinating blend of genetics and cultural practices. The ABCC11 gene variant plays a pivotal role in limiting the production of odorous sweat, while rigorous hygiene practices and dietary habits further enhance this genetic advantage. This unique combination offers valuable insights into human diversity and the intricate relationship between our genes and daily lives. Embracing this genetic gift allows for a greater appreciation of the biological and cultural factors that shape our experiences.
FAQs
Why do South Koreans have less body odor?
The primary reason is the high prevalence of the ABCC11 gene variant, which reduces the activity of apocrine sweat glands responsible for producing odorous sweat. Cultural practices focusing on cleanliness and diet also contribute.
Is the ABCC11 gene variant common in other populations?
The ABCC11 gene variant is most common in East Asian populations, including South Koreans. It is rare in European and African populations.
Can personal hygiene practices overcome genetic predispositions to body odor?
Yes, good personal hygiene practices can help manage body odor regardless of genetic predispositions. Regular bathing, the use of deodorants, and a balanced diet can significantly reduce body odor.
Does diet affect body odor?
Yes, diet plays a role in body odor. Foods rich in red meat and dairy can increase body odor, while diets high in vegetables and fish, common in South Korea, can help reduce it.
Are there other genetic factors influencing body odor?
While the ABCC11 gene is a significant factor, other genetic markers and environmental factors also play a role in body odor. Ongoing research aims to identify these additional factors.
Do South Koreans need to use deodorant?
Due to the high prevalence of the ABCC11 gene variant, many South Koreans have minimal body odor and often do not need to use deodorant. However, cultural norms and personal preferences may still lead some to use these products.
