10 Surprising Causes of Acne (And How to Avoid Them)

Acne is a common skin problem that affects millions of people worldwide.​ It can cause physical discomfort and emotional distress, leaving many desperate to find a solution.​ While most people are aware that factors such as hormones, genetics, and poor hygiene can contribute to acne breakouts, there are some surprising causes that are often overlooked.​ By understanding and avoiding these unexpected triggers, you can take proactive steps towards achieving clear and healthy skin.​

1.​ Excessive Stress: Stress has a major impact on our overall health, and the skin is no exception.​ When we experience stress, our bodies produce more cortisol, which can lead to increased oil production and clogged pores.​ To avoid stress-related breakouts, incorporate stress-reducing activities into your daily routine, such as exercise, meditation, or hobbies that you enjoy.​

2.​ Dirty Pillowcases: Did you know that your pillowcase could be the culprit behind your stubborn acne? As we sleep, oils, dead skin cells, and bacteria accumulate on our pillowcases, which can lead to breakouts.​ Make it a habit to change your pillowcase at least once a week to maintain a clean sleeping environment for your skin.​

3.​ High Glycemic Index Foods: The foods we consume have a direct impact on our skin.​ High glycemic index foods, such as white bread, sugary snacks, and processed foods, can cause a spike in blood sugar levels, leading to inflammation and increased oil production.​ Opt for low glycemic index alternatives, such as whole grains, fruits, and vegetables, to keep your skin clear and radiant.​

4.​ Heavy Makeup: While makeup can enhance our features and boost our confidence, using heavy, pore-clogging products can exacerbate acne breakouts.​ Look for non-comedogenic, oil-free makeup options that won’t clog your pores.​ Remember to cleanse your face thoroughly before going to bed to remove any lingering makeup residue.​

5.​ Excessive Sun Exposure: The warm sun may feel soothing on your skin, but excessive exposure can actually worsen acne.​ Sunburns cause inflammation, which can lead to breakouts.​ Additionally, some acne medications increase skin sensitivity to the sun.​ Protect your skin by wearing a broad-spectrum sunscreen with at least SPF 30 and seek shade during peak sun hours.​


Using Harsh Products: Harsh cleansers, toners, and exfoliators may seem like they’re doing a good job at tackling acne, but they can strip away the skin’s natural oils and disrupt its protective barrier.​ This can actually make acne worse in the long run.​ Opt for gentle, non-irritating products specifically formulated for acne-prone skin.​

7.​ Touching Your Face: Our hands come into contact with numerous surfaces throughout the day, picking up dirt and bacteria along the way.​ When we touch our face frequently, we transfer these impurities onto our skin, which can lead to breakouts.​ Break the habit by avoiding touching your face unnecessarily and regularly sanitizing or washing your hands.​

The Role of Diet in Acne Development

Many people are unaware of the significant impact that diet can have on acne development.​ While it was once believed that diet had no effect on skin health, recent studies have shown a link between certain foods and acne breakouts.​ Researchers have found that diets high in refined carbohydrates and sugar can exacerbate acne by increasing inflammation and oil production.​ Additionally, dairy has been implicated in acne development due to the hormones present in milk.​ To support clear skin, consider incorporating a balanced diet rich in fruits, vegetables, whole grains, and lean proteins, while minimizing the intake of refined carbohydrates and dairy products.​

Environmental Factors and Acne

Beyond what we put into our bodies, environmental factors also play a role in the development of acne.​ Air pollution, for example, can introduce toxins and irritants to the skin, leading to inflammation and breakouts.​ Additionally, excessive humidity can contribute to increased oil production, creating a breeding ground for acne-causing bacteria.​ To mitigate the impact of environmental factors on your skin, cleanse your face thoroughly each day and consider using a topical antioxidant to help defend against pollution.​ Additionally, using a humidifier or keeping your environment well-ventilated can help regulate humidity levels.​

Hormonal Factors and Acne

Hormonal imbalances are a well-known cause of acne, particularly in teenagers and women.​ Fluctuations in hormone levels can lead to increased oil production, clogged pores, and inflammation.​ Beyond puberty, hormonal acne can also be triggered by conditions such as polycystic ovary syndrome (PCOS) or certain medications.​ To manage hormonal acne, it may be necessary to explore medical treatment options, such as birth control pills or medication that targets hormone regulation.​ Consulting with a healthcare professional will help determine the most suitable course of action.​

The Impact of Lifestyle Choices on Acne

Our daily lifestyle choices can greatly influence our skin’s health and the occurrence of acne breakouts.​ Lack of sleep, for example, can disrupt the body’s natural healing processes and lead to increased inflammation.​ Additionally, smoking has been linked to increased acne severity due to its negative effects on circulation and oxygen supply to the skin.​ By prioritizing healthy sleep habits and avoiding smoking, you can support your skin’s natural healing processes and decrease the likelihood of acne breakouts.​
