Understanding the Causes of Acne: Why Do We Get Pimples?

Acne affects millions of Americans, making it one of the most common skin conditions patients face. At Atomic Dermatology and Med Spa, we understand that dealing with persistent acne can be both physically and emotionally challenging. Finding the right acne treatment can feel overwhelming, whether you’re a teenager experiencing your first breakout or an adult with recurring blemishes. Understanding what causes acne is the first step toward effective management. While over-the-counter acne medication might work for some, others require professional guidance to identify the best acne treatment for their skin concerns.

What Exactly is Acne?causes of acne

Acne is more than just an occasional pimple. It’s a complex skin condition characterized by inflammation of the hair follicles and oil glands. When we examine acne under a microscope, we see that it develops when hair follicles become plugged with oil and dead skin cells, creating the perfect environment for bacteria to thrive.

Different types of acne present in various ways:

  • Blackheads: Open plugged pores that appear darker due to oxygen exposure
  • Whiteheads: Closed plugged pores that maintain a white or flesh-colored appearance
  • Papules: Small, tender red bumps
  • Pustules: Papules with pus at their tips
  • Nodules: Large, solid, painful lumps beneath the skin
  • Cysts: Painful, pus-filled lumps beneath the skin that can cause scarring

The Main Causes of Acne

To effectively address acne, it’s essential to understand the fundamental biological processes behind it. Here are four key factors that contribute to acne formation:

1. Excess Oil (Sebum) Production

Our skin naturally produces an oily substance called sebum that helps keep skin hydrated and protected. However, certain factors can trigger the overproduction of sebum, especially during hormonal fluctuations. This excess oil becomes a primary contributor to acne development, making oil control a crucial part of any acne treatment strategy.

2. Clogged Hair Follicles

Dead skin cells typically rise to the surface and shed naturally. However, when excess sebum is present, these cells can stick together and become trapped inside the follicle. This creates the perfect environment for acne to develop. Professional exfoliation treatments and appropriate acne medication can help address this underlying cause.

3. Bacterial Overgrowth

Propionibacterium acnes (P. acnes) bacteria live on everyone’s skin. However, when follicles become clogged with oil and dead skin cells, these bacteria multiply rapidly, causing the inflammation and infection associated with pimples, leading to skin damage and scarring. The best acne treatment plans often include antibacterial components to address this factor.

4. Inflammation

The body’s immune response to bacterial overgrowth results in inflammation—the redness, swelling, and pain that characterize acne lesions. Reducing inflammation is key to treating existing breakouts and preventing new ones.

Common Triggers and Contributing Factorsmedical grade products for acne

While understanding the biological processes behind acne is important, identifying your triggers can be even more valuable for managing breakouts. At Atomic Dermatology, we help patients identify these factors during comprehensive skin evaluations:

1. Hormonal Changes

Hormonal fluctuations remain one of the most common acne triggers. These can occur during puberty, menstrual cycles, pregnancy, perimenopause, and menopause, or with specific conditions like polycystic ovary syndrome (PCOS). Hormonal changes stimulate the sebaceous glands, increasing oil production and creating conditions favorable for acne development. Our customized acne treatment approaches often address these underlying hormonal influences.

2. Diet and Lifestyle

Emerging research continues to strengthen the connection between diet and acne. High-glycemic foods that spike blood sugar and dairy products may trigger or worsen breakouts in some individuals. Chronic stress, insufficient sleep, inadequate hydration, and lack of regular exercise can all contribute to skin concerns. Our holistic approach to acne medication and treatment includes lifestyle recommendations alongside clinical interventions.

3. Genetics

Family history plays a significant role in determining your likelihood of developing acne. If your parents struggled with acne, you may have inherited similar skin characteristics. While you can’t change your genetics, understanding this predisposition helps develop more effective preventative strategies.

4. Skincare Products and Cosmetics

Some skincare products and cosmetics contain ingredients that can clog pores (comedogenic) or irritate sensitive skin. With the many choices in modern skincare, it can be hard to navigate which products and ingredients are best for you. At Atomic Dermatology and Med Spa, we help patients identify problematic products and recommend non-comedogenic alternatives that won’t interfere with their acne treatment plan.

5. Environmental Factors

Living in Pasco and the Tri-Cities area means dealing with specific environmental challenges that can affect skin health. These include seasonal changes, hot temperatures, exposure to dust and pollutants, and hard water, all of which can contribute to skin irritation and acne flare-ups. The best acne treatment plans account for these local environmental considerations.

6. Specific Medications

Certain medications can trigger or worsen acne as a side effect, including corticosteroids, lithium, some hormonal contraceptives, testosterone supplements, and antidepressants. Never discontinue prescribed medication without consulting your healthcare provider, but inform our dermatologists about all your medications so we can develop an appropriate acne treatment strategy.

For example, if you’re experiencing persistent or recurring acne despite over-the-counter treatments or have moderate to severe acne with painful cysts, nodules, or scarring.
