In fact, Taylor et al27 found acne hyperpigmented macules present in 65.3 percent of African-American, 52.7 percent of Hispanic, and 47.4 percent of Asian patients with acne. Keloid formation (Figure 7) and hypertrophic scarring are other sequelae of acne more commonly seen in the skin of color populations.
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%).
Germany's teenagers and young people have the highest rates of acne in the world, according to a major study, with the UK in eighth place.
Women are more likely to have adult acne than men. It's thought that many cases of adult acne are caused by the changes in hormone levels that many women have at certain times. These times include: periods – some women have a flare-up of acne just before their period.
Temperature and Humidity
The study showed that hot weather was risk factors for acne. However, Dreno et al. found there was no significant difference in prevalence of people with or without acne living in temperate or cold regions.
Notably, our analysis identified a strong association between acne prevalence and specific lifestyle factors, including high intake of fast foods, reduced sleep duration, and low physical activity levels.
Updated 9/10/19. After moving to a new state or country, many can experience some changes in their skin and its appearance. This might include rashes, dryness, sensitivity, bumps, increased breakouts or oil production.
To determine whether women were prone to acne, we further stratified the prevalence of acne by gender. The prevalence was higher in women, at a rate of 6.06% (95% CI, 5.99%–6.12%), than in men, at a rate of 3.34 (95% CI, 3.29%–3.39%). Male to female ratio of prevalence is around 1 : 1.81.
Acne is a common issue for many people, especially for teenagers and young adults in their 20s. 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.
One of the primary reasons why some individuals never experience pimples is due to their genetic makeup. Certain people inherit genes that make them less prone to excessive oil production or the formation of clogged pores, which are common factors contributing to pimples.
Acne conglobata (AC) is a rare but severe form of nodulocystic acne. It usually presents with tender, disfiguring, double or triple interconnecting comedones, cysts, inflammatory nodules, and deep burrowing abscesses on the face, shoulders, back, chest, upper arms, buttocks, and thighs.

Conclusions. The self-declared prevalence of acne is relatively high in European adolescents even if there are variations across countries. Heredity is the main identified risk factor for developing acne whereas age is negatively associated with the prevalence of this condition.
It is perhaps underappreciated that acne is more common in people with darker Fitzpatrick skin types (FSTs) than in those with lighter skin. For example, in one large (N = 2,895) study, acne was observed in 37% of African American women and 32% of Hispanic women, compared with 24% of Caucasian women.
Oily Skin Type
Dull or shiny, thick complexion. Blackheads, pimples, or other blemishes.
Acne vulgaris is one of the top three most commonly encountered dermatological problems worldwide in both primary and secondary care. Acne diagnosis and treatment date back to ancient Greek and Egyptian times.
Most people have acne on and off for several years before their symptoms start to improve as they get older. Acne often disappears when a person is in their mid-20s. In some cases, acne can continue into adult life. About 3% of adults have acne over the age of 35.
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.
Rates of nodulocystic acne were significantly lower in African-American subjects. However, Hispanics and Asians are thought to have similar prevalence rates of nodulocystic acne as Caucasians, although supporting evidence is lacking.
But there definitely is a tendency for acne to run in families. If either (or both) of your parents are acne-prone, that may be one reason you are as well. 1 Some studies have shown a person's likelihood of developing acne if her mother had acne at any point in her life is especially high.
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%).
“If you have acne, don't worry, I've got good news - people with acne live longer. People who suffer from acne age slower than those with clear skin, so if you suffer from acne - good for you,” says Sungjemlila Longkumer, an Indian skinfluencer, on an Instagram Reel.
Joel Schlessinger explains, “During summer months, the temperatures rise and so does the humidity. This triggers sebaceous glands to produce more oil which mixes with sweat, dirt and dead skin cells, which congests and blocks pores. This leads to a shiny complexion and more breakouts, blackheads and whiteheads.”
