Cultures with traditional, non-Westernized lifestyles, such as the Kitavan Islanders (Papua New Guinea) and Aché hunter-gatherers (Paraguay), historically show virtually no acne, suggesting environmental factors (like diet) play a larger role than genetics, though modernizing populations see increased rates. Generally, European and Australian populations tend to have lower prevalence in modern studies compared to Latin America, East Asia, Africa, and the Middle East, but traditional diets are key to minimal acne.
The highest prevalence of acne was observed in Latin America (23.9%), East Asia2 (20.2%), Africa (18.5%) and the Middle East (16.1%), while the lowest prevalence was observed in Europe (9.7%) and Australia (10.8%).
Herein we report the absence of acne in 2 nonwesternized populations: the Kitavan people living on the Trobriand Islands near Papua New Guinea and the Aché hunter-gatherers of Paraguay. Additionally, we evaluate how elements in nonwesternized environments may influence the development of acne.
“At the national level in 2021, India, China, Nigeria, Indonesia and the USA had the highest number of prevalent cases of acne vulgaris among adolescents and young adults,” the authors wrote. India reported the highest number of cases with 30.7 million cases, followed by China where 26.3 million cases were reported.
Asian skin produces more oil due to the warmer climates of the regions. As a result, Asians are more vulnerable than others to acne outbreaks. In most cases, the breakouts are keloids, hardened bumps. Unfortunately, without treatment, this can lead to acne scarring.
Asian skin, which can range from very light to dark, contains more collagen than other ethnic skin types. This collagen helps stave off wrinkling that can occur earlier in people of other ethnicities – so many Asians look young well into their 50s.
Asians in general have more melanin and more numerous melanocytes in the skin compared to Caucasian skin. Even fair-skinned Asians have more melanocytes than most Caucasians.
Thus previous studies showed a heritability estimate ranging from 50-90% for acne. In other words, approximately 50-90% of acne was due to genetic variation in the affected individuals. A large UK study involving 400 twin pairs showed that 81% of acne was due to genetic factors.
How acne develops. Acne develops when sebum — an oily substance that lubricates your hair and skin — and dead skin cells plug hair follicles. Bacteria can trigger inflammation and infection resulting in more severe acne.
The bacteria that cause acne live on everyone's skin, yet one in five people is lucky enough to develop only an occasional pimple over a lifetime.
Among isolated populations in Papau New Guinea and Paraguay, no active acne was observed. The researchers thought that, while there was likely to be a genetic contribution, it was highly probably that the natural non-Westernised diets in these populations were an important protective factor.
Acne is well-known since ancient times and is avowed to affect people even before humans could write. 7,8 Since it has a long history, hence is now known as one of the world's most common skin disorder.
Acne fulminans is the rarest but also the most severe form of acne. Unlike other forms of acne which are chronic, acne fulminans is an acute form of the disease. Acne fulminans appears abruptly, mainly in boys during adolescence.
In 2011, Perkins et al27 compared the frequency of acne in “Caucasian, Asian, Continental Indian, and African American” women (N=2,895), and reported acne was observed in 37 percent of African American women (FST V-VI), 32 percent of Hispanic women (FST II-V) and 30 percent of Asian descent (FST II-VI) compared with 24 ...
Acne, one of the most common skin disorders, peaks in adolescence and early adulthood, affecting around 85% of people between the ages of 12 and 24.
Attack the different causes of acne.
Benzoyl peroxide decreases P. acnes bacteria. Retinoids, such as adapalene gel, unclog pores and reduce oiliness. Salicylic acid eases inflammation and unclogs pores.
Some have mild symptoms, while others can have very severe issues. Acne effects around 90% of adolescents with the prime age across all genders being the teenage years of 14-19 years old.
Spoiler alert—no! Using toothpaste to treat acne can cause dryness and irritation. We're here to share what we know — but don't take it as medical advice. Talk to your medical provider if you have questions.
A regular skincare routine that includes cleansing, exfoliating, and moisturizing can help prevent new breakouts and reduce the risk of scarring. Use gentle exfoliants to remove dead skin cells and promote cell turnover, which can help improve the appearance of existing scars over time.
While we often think that acne is linked to poor health or skincare habits, oftentimes it can be linked to medical conditions elsewhere in the body. The location and severity of acne can be an indication of the cause of acne.
Abstract. Traditionally, Asians have been thought to age more gracefully than Caucasians. The resistance to aging in the Asian patient was credited to the thicker dermis of Asian skin that contains greater collagen and the darker pigment that protects against photoaging.
Most beautiful Asian women!
Collagen Density and Skin Structure
Some ethnicities naturally have higher collagen density in their skin, which can delay the appearance of wrinkles and sagging. - Ethnicities with higher collagen density: Studies show that East Asian and African ethnicities tend to have denser and more resilient collagen structures.
Japan, China and other countries located in Asia have a rich diet of vitamins (specifically A and C, which benefit skin elasticity) and minerals including antioxidants from fruits and green tea. The Asian diet is very low in saturated and total fat.
