Acne is a common skin condition that can affect individuals of all ages, with varying degrees of severity. While it is often associated with puberty, it can persist or develop well into adulthood. Understanding the potential causes of acne can help clarify why breakouts occur and how to address them. Both individuals and dermatology professionals can work together to support healthier, clearer skin.

Dermatology Perspectives on Acne Causes
The field of dermatology may emphasize the multifactorial nature of acne, but it is not just one cause but a combination of factors. From hormonal fluctuations to environmental triggers, there are various things that can lead to breakouts. Dermatologists also recognize that certain medications and underlying health conditions can play a role in acne development. Medications such as corticosteroids and lithium are known to potentially cause or worsen acne in some individuals.
Hormonal Changes
Hormonal changes are among the contributors to acne. Surges in hormone levels, particularly during puberty, pregnancy, or menstrual cycles, can lead to increased oil production in the skin. This excess oil, known as sebum, can clog pores and create an environment where acne-causing bacteria thrive.
Androgens, a type of hormone, are commonly linked to this process. When androgen levels rise, the sebaceous glands in the skin become overactive, producing more sebum than necessary. This excess oil combines with dead skin cells within the pores, contributing to the formation of blackheads, whiteheads, and inflamed pimples. These hormonal shifts are not limited to adolescents. Many adults experience hormonal acne due to hormonal birth control, menopause, or underlying endocrine conditions.
Genetics
Genetics can influence an individual’s susceptibility to acne. A predisposition to acne often runs in families. Studies indicate that genetics affect factors like sebum production, skin inflammation responses, and the likelihood of pores becoming blocked. While genetic predisposition alone does not guarantee the development of acne, it can increase sensitivity to other contributing factors, such as hormonal changes or external triggers.
Diet
Dietary choices may also influence the development of acne. Though dermatology research is ongoing in this area, certain foods have been linked to an increased risk of breakouts. High-glycemic index foods, such as sugary snacks, white bread, and pasta, may lead to elevated blood sugar levels. These spikes in blood sugar can trigger excessive insulin production, which in turn may contribute to increased sebum production and inflammation.
Dairy products have also been studied for their potential role in acne. Some researchers suggest that hormones present in milk and other dairy products could interact with the body’s own hormone levels, potentially contributing to acne. While dietary adjustments alone may not eliminate acne, they can provide supportive benefits.
Environmental and Lifestyle Factors
Environmental and lifestyle factors can exacerbate acne. Exposure to pollutants and humid conditions may contribute to clogged pores and irritation of the skin. Likewise, makeup and skincare products can block pores, increasing the likelihood of breakouts. Regular use of harsh or abrasive skincare products can also negatively affect the skin’s barrier function, making it more vulnerable to irritation and breakouts.
Stress is another significant lifestyle factor. Though stress does not directly cause acne, it can exacerbate existing conditions. When stressed, the body produces cortisol, a hormone that can stimulate sebaceous glands to release more sebum. This process often leads to inflammatory acne flare-ups.
Take the Next Step for Clearer Skin
Acne can be influenced by factors from hormonal changes to lifestyle and environmental triggers. While this condition can be persistent and complex, identifying potential causes is a good first step toward effective management. For those looking to better understand how to address acne, consulting with a dermatologist can provide personalized insight and recommendations.
