Acne is extremely common in Australia, affecting around 85% of Australians aged 12-24, with nearly 94% of 16-18 year olds experiencing it, making it almost universal in teenagers and a significant issue for many adults, impacting self-esteem and quality of life, notes RACGP and this Pharmaceutical Society of Australia article. It's the most common skin disease, persisting into adulthood and affecting up to half of people in their 30s, with various treatment options available.
Did you know that acne is one of the most common skin diseases in Australia? If you have acne, you're not alone. It's the most common skin disease – affecting 85% of Australians aged 15-24 years old*. And it doesn't matter whether you're male or female as both sexes get 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%).
Background In westernized societies, acne vulgaris is a nearly universal skin disease afflicting 79% to 95% of the adolescent population. In men and women older than 25 years, 40% to 54% have some degree of facial acne, and clinical facial acne persists into middle age in 12% of women and 3% of men.
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. Though it is often thought of as a teenage problem, acne can occur in people of any age, though it grows less common as time goes on.
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.
You can't completely prevent acne, especially during hormone changes, but you can reduce your risk of developing acne by: Washing your face daily with warm water and a facial cleanser. Using an oil-free moisturizer. Wearing “noncomedogenic” makeup products and removing makeup at the end of each day.
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.
In a study involving almost 3,000 adult women from Los Angeles, USA; London, UK; Akita, Japan; and Rome Italy, rates of acne differed by ethnicity with 37 percent of Black individuals with acne, 32 percent of Hispanic, 39 percent of Asian, 24 percent of White individuals, and 23 percent of continental Indian women.
High-glycemic foods such as white bread, sugary snacks, and processed foods cause insulin spikes. These spikes increase oil production in the skin, leading to clogged pores and more acne. A 2023 study found that 70% of people consuming high-glycemic diets experienced worse acne than those on low-glycemic plans.
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.
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.
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.
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.

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.
Acne vulgaris is a common skin condition among Japanese individuals, including adolescent and young adult women, with 64.8 percent of adolescents reporting acne in a recent epidemiological study by Kubota et al.
The findings reveal a notable increase in the global age-standardised prevalence rate of acne vulgaris from 1990 to 2021, rising from 8563 to 9791 per 100,000 population. In Australasia the number has remained relatively steady from 1990 to 2021, rising from 9225 to 9792 per 100,000.
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.
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.
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.
TOP FOODS THAT CAUSE PIMPLE AND BREAKOUTS
Acne Reduction
Inflammation associated with acne can cause redness, swelling, and soreness in pimples and pustules (pus-filled pimples). Applying honey to the affected area can help reduce the bacteria that make acne worse. It can also calm inflammation, reducing any redness and puffiness surrounding pimples.
Your body can gradually break down pus and reabsorb its components. That's why small accumulations of pus (like in a pimple) often don't need treatment.
