What Is Acne?

Acne, medically referred to as acne vulgaris, is a chronic inflammatory skin disorder that affects the pilosebaceous unit, which includes hair follicles and sebaceous (oil-producing) glands.

Acne most commonly appears on:

The face

Chest

Upper back

Shoulders

These areas contain a high concentration of oil glands, making them more prone to breakouts.

Acne can present as:

Blackheads

Whiteheads

Pimples

Painful cysts

Nodules

Acne scars and dark marks

Although acne is most common during adolescence, adult acne is increasingly prevalent, especially among women between the ages of 25 and 45.

How Acne Develops: Understanding the Root Causes -

Acne forms due to the interaction of four core biological processes:

1. Excess Sebum Production

Sebaceous glands produce oil (sebum) to protect the skin. During puberty and hormonal fluctuations, androgens stimulate these glands to produce excess oil, which can clog pores.

2. Abnormal Skin Cell Shedding

Normally, dead skin cells shed from the pore lining. In acne-prone skin, these cells stick together and accumulate, blocking pores.

3. Bacterial Overgrowth

Cutibacterium acnes (formerly Propionibacterium acnes) thrives in clogged pores, feeding on sebum and triggering inflammation.

4. Inflammation

The immune system responds to bacterial growth by releasing inflammatory chemicals, leading to redness, swelling, and pain.

When these processes occur together, acne lesions form.

Different Types of Acne (Know Your Acne Type) -

Understanding the type of acne you have is essential for choosing the right treatment.

Non-Inflammatory Acne

Blackheads (Open Comedones)

These occur when pores are clogged but remain open. The dark color is caused by oxidation, not dirt.

Whiteheads (Closed Comedones)

These form when pores are clogged and closed under the skin.

Inflammatory Acne

Papules

Small red, tender bumps without visible pus.

Pustules

Red pimples filled with pus.

Nodules

Large, deep, painful lumps beneath the skin surface.

Cysts

Severe, pus-filled lesions that often result in scarring.

Acne-Like Conditions (Often Misdiagnosed)

Fungal acne (Malassezia folliculitis)

Rosacea

Perioral dermatitis

Folliculitis

These conditions require different treatments, so proper diagnosis is critical.

What Causes Acne? Major Triggers Explained

Acne is a multifactorial condition, meaning several factors contribute simultaneously.

Hormonal Changes

Hormones play a central role in acne development. Common hormonal triggers include:

Puberty

Menstrual cycles

Pregnancy

Polycystic ovary syndrome (PCOS)

Menopause

Hormonal acne often appears along the jawline, chin, and lower cheeks.

Genetics -

If acne runs in your family, you are more likely to experience it. Genetics influence oil production, inflammation, and skin cell turnover.

Stress -

Stress increases cortisol levels, which can stimulate oil production and worsen inflammation.

Skincare and Cosmetics -

Using comedogenic or heavy products can clog pores. Over-cleansing and harsh scrubs damage the skin barrier, worsening acne.

Environmental Factors

Pollution, humidity, sweating, and occlusive clothing or helmets can contribute to breakouts.

Medications -

Certain medications such as corticosteroids, lithium, testosterone, and some birth control types may trigger acne.

Acne Myths vs Facts

Myth: Acne is caused by dirty skin

Fact: Acne is not caused by poor hygiene. Over-washing can worsen acne.

Myth: Sun exposure clears acne

Fact: Sun temporarily dries oil but increases inflammation, pigmentation, and aging.

Myth: Popping pimples helps them heal

Fact: Picking increases infection risk and causes scars.

Myth: Only teenagers get acne

Fact: Adult acne is extremely common.

Acne by Age and Gender

Teenage Acne

Triggered by puberty hormones, commonly affects the forehead, nose, and chin.

Adult Acne

Often persistent or late-onset, especially in women, frequently hormonal in nature.

Male Acne

Men tend to have more severe acne due to higher androgen levels, often affecting the chest and back.

Diet and Acne: What Research Shows

Diet does not cause acne directly, but it can influence severity in some individuals.

Foods That May Worsen Acne -

High-glycemic foods (white bread, sugary snacks)

Sugary beverages

Processed foods

Skim milk and some dairy products

High-glycemic foods raise insulin and insulin-like growth factor-1 (IGF-1), which increases oil production.

Foods That May Improve Acne

Omega-3 fatty acids (fatty fish, walnuts)

Zinc-rich foods (pumpkin seeds, lentils)

Fruits and vegetables rich in antioxidants

Low-glycemic whole foods

Personalized Nutrition Approach

Dietary triggers vary. A 4–6 week elimination trial can help identify personal acne triggers.

---

Lifestyle Factors That Affect Acne

Sleep

Poor sleep increases inflammatory markers and hormonal imbalance.

Exercise

Regular exercise improves insulin sensitivity and reduces stress, but sweat should be washed off promptly.

Stress Management

Mindfulness, yoga, meditation, and regular physical activity can reduce stress-related breakouts.
