What Causes Acne? Hormones, Diet, Stress & Medications Explained

Introduction

Acne is one of the most common skin conditions affecting teenagers, adults, and even older individuals. Many people believe acne is only caused by oily skin or poor hygiene, but the reality is far more complex. Hormones, diet, stress, medications, genetics, and lifestyle factors all play a crucial role in acne development.

Understanding what causes acne is the first step toward effective treatment and long-term prevention. In this detailed guide by Ivermectinkart, we explain the real causes of acne, how different factors trigger breakouts, and what you can do to manage acne safely and effectively.

What Is Acne?

Acne is a chronic inflammatory skin condition that occurs when hair follicles become clogged with oil (sebum), dead skin cells, and bacteria. This blockage leads to different types of acne lesions, including:

• Whiteheads

• Blackheads

• Papules

• Pustules

• Nodules

• Cysts

Acne most commonly appears on the face, chest, back, shoulders, and upper arms.

Primary Causes of Acne

1. Hormonal Imbalance and Acne

Hormones are one of the biggest causes of acne, especially during:

• Puberty

• Menstrual cycles

• Pregnancy

• Polycystic Ovary Syndrome (PCOS)

• Menopause

Androgens (male hormones present in both men and women) increase during these stages, stimulating excess oil production. This excess oil clogs pores and promotes acne-causing bacteria.

Hormonal acne typically appears on the:

• Jawline

• Chin

• Lower cheeks

2. Diet and Acne Connection

Diet plays a significant role in acne development. Research shows that certain foods may worsen acne by increasing inflammation and insulin levels.

Foods that may trigger acne include:

• Sugary foods

• White bread and refined carbs

• Fast food and fried foods

• Dairy products (especially skim milk)

• Processed snacks

Acne-friendly foods include:

• Fruits and vegetables

• Whole grains

• Omega-3 fatty acids

• Zinc-rich foods

A poor diet can increase oil production and inflammation, worsening acne symptoms.

3. Stress and Acne Breakouts

Stress does not directly cause acne, but it can significantly worsen existing acne. When you’re stressed, your body releases cortisol, a stress hormone that increases oil production in the skin.

Stress-related acne is common during:

• Exams

• Work pressure

• Emotional trauma

• Sleep deprivation

Managing stress through meditation, exercise, and proper sleep can improve acne over time.

4. Medications That Cause Acne

Certain medications can trigger or worsen acne as a side effect. These include:

• Corticosteroids

• Hormonal contraceptives

• Testosterone therapy

• Lithium

• Certain anti-epileptic drugs

Medication-induced acne often appears suddenly and may not respond to typical acne treatments.

5. Excess Oil (Sebum) Production

Sebaceous glands naturally produce oil to protect the skin. However, excessive oil production can clog pores and trap bacteria, leading to acne.

Oily skin is influenced by:

• Genetics

• Hormones

• Climate

• Skincare products

6. Clogged Pores and Dead Skin Cells

When dead skin cells do not shed properly, they mix with oil and block hair follicles. This creates an ideal environment for acne-causing bacteria to grow.

Using harsh scrubs can actually worsen this condition by irritating the skin.

7. Bacteria and Inflammation

A specific bacteria present on the skin multiplies inside clogged pores, triggering inflammation. This results in red, swollen, and painful acne lesions.

Inflammatory acne is harder to treat and may lead to scarring if not managed properly.

8. Genetics and Family History

If your parents had acne, you are more likely to develop it. Genetics influence:

• Oil production

• Skin cell turnover

• Inflammatory response

9. Lifestyle and Environmental Factors

Other contributors to acne include:

• Poor sleep

• Smoking

• Pollution

• Touching the face frequently

• Dirty pillowcases or makeup brushes
