Acne

Acne is a common skin condition that affects individuals of all ages, particularly during adolescence. Characterized by pimples, blackheads, and cysts, acne can impact not only physical appearance but also emotional well-being. Understanding its causes, types, and treatment options is essential for effective management and prevention.

Acne is a chronic inflammatory skin condition that occurs when hair follicles become clogged with oil and dead skin cells. This blockage leads to the formation of pimples, blackheads, whiteheads, and, in severe cases, cysts or nodules. While often associated with teenagers, acne can affect people at any age.

India

In India, acne is highly prevalent among adolescents and young adults. A study revealed that approximately 72% of Indian school children experience acne, significantly impacting their quality of life.

Worldwide

Globally, acne affects about 9.4% of the population, making it one of the most common skin conditions. The highest prevalence is observed among adolescents aged 16 to 24 years, with rates reaching up to 28.3% in this age group.

Understanding the different types of acne is crucial for effective treatment:

• Whiteheads (Closed Comedones): Small, flesh-colored bumps caused by clogged pores.
• Blackheads (Open Comedones): Dark spots resulting from oxidized clogged pores.
• Papules: Small, red, tender bumps without pus.
• Pustules: Red, inflamed bumps filled with pus.
• Nodules: Large, painful lumps beneath the skin's surface.
• Cysts: Deep, painful, pus-filled lesions that can cause scarring.

Acne is a multifactorial skin condition, meaning that it can be caused by a combination of internal and external factors. Understanding these causes can help in both preventing and managing breakouts effectively. Here's a comprehensive look at what typically triggers acne:

1. Excess Sebum Production

The skin naturally produces oil (sebum) through sebaceous glands to keep it moisturised and protected. However, in people with acne, these glands often produce too much oil, especially during puberty or due to hormonal fluctuations. This excess oil can mix with dead skin cells and block pores, creating the ideal environment for breakouts.

2. Hormonal Changes

One of the most common causes of acne—especially in teenagers and adult women—is hormonal imbalance. During puberty, androgens (male hormones present in both sexes) increase, stimulating sebaceous glands to enlarge and produce more sebum. In adult women, fluctuations around menstruation, pregnancy, or conditions like polycystic ovarian syndrome (PCOS) can also lead to acne.

3. Blocked Hair Follicles (Clogged Pores)

Each hair follicle on the skin is connected to a sebaceous gland. When these follicles get blocked with oil and dead skin cells, it results in a comedone (blackhead or whitehead). These blocked pores can then develop into inflamed acne if infected by bacteria.

4. Bacterial Infection – Cutibacterium acnes

This naturally occurring skin bacterium (formerly called Propionibacterium acnes) becomes problematic when it multiplies rapidly in clogged pores. It triggers inflammation by attracting white blood cells to the site, leading to redness, swelling, pus, and painful lesions like papules or cysts.

5. Genetic Predisposition

If your parents had acne, chances are you may be more prone to it too. Genetics influence how your body produces sebum, how quickly your skin regenerates, and how you respond to inflammation—all of which affect acne risk.

6. Diet and Lifestyle

While diet doesn't directly cause acne, studies suggest that high-glycaemic foods, sugary snacks, and excessive dairy may aggravate breakouts in some individuals. Poor sleep, high stress, and lack of exercise can also throw off hormonal balance, contributing to flare-ups.

7. Certain Medications

Drugs that contain corticosteroids, androgens, lithium, or some antiepileptic medications can lead to acne as a side effect. It’s known as drug-induced acne and may need a change in treatment if severe.

8. Cosmetic and Skincare Products

Using products that are comedogenic (pore-clogging) or too harsh for your skin type can cause acne, particularly on the face and neck. Always check product labels for “non-comedogenic” or “oil-free” formulations.

9. Environmental Factors

Excessive humidity, sweating, or working in oily environments (like kitchens) can lead to a type of acne called acne mechanica. Pollution can also clog pores and irritate the skin, making acne worse.

10. Friction and Pressure on the Skin

Consistent pressure or rubbing from helmets, face masks, tight collars, or even mobile phones can irritate the skin and lead to mechanical acne.

Common symptoms include:

• Whiteheads and blackheads
• Red, tender bumps (papules)
• Pus-filled pimples (pustules)
• Painful lumps under the skin (nodules)
• Scarring and dark spots post-healing
   

Diagnosing acne is typically straightforward and primarily based on a visual examination of the skin. A dermatologist or general physician can often identify acne by looking at the affected areas, such as the face, chest, back, or shoulders.

Steps in Diagnosis

Medical History:

• The doctor will ask about your symptoms, duration of breakouts, family history, and lifestyle habits such as diet, skincare routine, and stress levels.
• In women, information about the menstrual cycle, hormonal imbalances, and use of oral contraceptives may be relevant.

Skin Examination:

• The type of lesions (e.g. blackheads, whiteheads, papules, nodules) and the severity of inflammation are assessed.
• The distribution pattern of acne also provides clues — for instance, acne on the lower jawline in adult women is often hormonally driven.

Grading the Severity:

• Acne can be categorised into mild, moderate, or severe, which helps determine the appropriate treatment approach.
• Tools such as the Global Acne Grading System (GAGS) may be used in clinical settings to score acne severity.

Additional Tests (if needed):

• Hormonal Testing: In cases of persistent or late-onset acne, especially in women, tests may be done to check for polycystic ovarian syndrome (PCOS) or androgen excess.
• Bacterial Culture: If acne does not respond to conventional treatment or shows signs of infection, a swab may be taken to test for resistant bacteria.
• Skin Biopsy (rare): If there's uncertainty about the diagnosis or to rule out similar skin conditions like rosacea, a small skin sample may be analysed.

Effective acne treatment depends on severity:

Topical Treatments:

• Benzoyl Peroxide: Kills bacteria and reduces inflammation.
• Retinoids (e.g., Tretinoin): Promote cell turnover and prevent clogged pores.
• Antibiotics (e.g., Clindamycin): Reduce bacteria and inflammation. (Brand available: Acnestar)
• Salicylic Acid: Helps unclog pores and exfoliate the skin.

Oral Medications:

• Antibiotics (e.g., Doxycycline): For moderate to severe acne.
• Hormonal Therapies: Birth control pills can regulate hormones in women.
• Isotretinoin: A potent drug for severe, cystic acne.

Procedural Treatments:

• Chemical Peels: Remove the top skin layer to reduce lesions.
• Laser and Light Therapies: Target bacteria and reduce oil production.
• Drainage and Extraction: For large cysts.

While conventional medical treatments remain the gold standard, many people seek complementary or natural approaches to help manage acne. Some of these therapies have anecdotal support, while others have emerging scientific backing.

1. Herbal Remedies & Essential Oils:

• Tea Tree Oil: Known for its antibacterial and anti-inflammatory properties. It may reduce mild to moderate acne when diluted and applied topically.
• Neem and Turmeric: Traditional Indian remedies believed to possess antimicrobial properties, sometimes used in face packs or cleansers.
• Aloe Vera: Applied as a gel, aloe vera can soothe inflamed skin and may support healing.
   

2. Nutritional Supplements:

• Zinc: Oral zinc supplements may help reduce inflammation and bacterial growth in some people with acne.
• Vitamin A: Not to be confused with prescription retinoids, low-dose vitamin A may assist skin health. However, high doses can be toxic — use only under medical guidance.
• Omega-3 Fatty Acids: Found in flaxseed, chia, and fish oil, these may help reduce inflammation associated with acne.
   

3. Mind-Body Therapies:

• Stress Reduction Techniques: Yoga, meditation, deep breathing, and journaling can help manage stress, which is known to aggravate acne.
• Acupuncture: Though evidence is limited, some individuals find improvement in skin clarity and hormonal balance through acupuncture sessions.
   

4. Homeopathy & Ayurveda:

• Homeopathic Treatments: These are personalised remedies based on individual symptoms and body constitution, though clinical evidence is limited.
• Ayurvedic Treatments: Treatments may include Triphala, Manjistha, or dietary regulation aimed at balancing 'Pitta' dosha.

Alternative therapies should not replace medical treatments in moderate to severe acne. Always consult a healthcare provider before starting any natural or herbal remedies.
