1. Introduction to Acne Vulgaris

Acne vulgaris is a long-term skin condition that occurs when hair follicles become clogged with oil and dead skin cells. It’s extremely common, especially during adolescence, but it can affect adults too.

• Affects around 8 in 10 teenagers
• Impacts about half of all adults, particularly women
• Most commonly shows up on the face, back, chest, and shoulders

Why Does It Happen?

There are four main reasons acne appears:

• Overproduction of oil (sebum) by the skin
• Blocked pores from dead skin cells
• Growth of acne-causing bacteria inside clogged pores
• Inflammation caused by the immune response

2. How Acne Forms (Step-by-Step)

Acne doesn’t appear overnight. It follows a chain reaction in your body:

1. Hormonal Changes – Especially androgens like testosterone, which increase oil production
2. Pore Blockage – Dead skin and oil mix together and plug up the hair follicles
3. Formation of a Plug – This is the early stage called a microcomedone
4. Bacterial Overgrowth – Blocked pores create the perfect home for bacteria
5. Inflammation – The immune system reacts, causing redness and swelling

Hormonal changes due to puberty, periods, stress, pregnancy, or conditions like PCOS can trigger this process.

3. Common Types of Acne

Acne Type	Description
Blackheads	Open pores filled with oil and dead cells that darken when exposed to air
Whiteheads	Closed clogged pores that remain under the skin surface
Papules	Small, red, raised bumps without pus
Pustules	Pimples that are red at the base with visible white pus at the top
Nodules	Deep, solid, painful lumps under the skin
Cysts	Large, pus-filled lesions that may scar

4. What Causes Acne?

Main Causes:

• Too much oil production
• Pores clogged by skin debris
• Bacterial buildup (C. acnes)
• Inflammation response

Common Triggers:

• Genetics (runs in families)
• Hormonal shifts (puberty, menstruation, birth control, PCOS)
• Certain foods (sugary, high-carb, dairy-heavy diets)
• Stress (raises cortisol, which boosts oil production)
• Medications like steroids or lithium
• Skincare or makeup that clogs pores

5. Symptoms & Acne Severity

Mild Acne:

• A few pimples, blackheads, or whiteheads
• Usually limited to the face

Moderate Acne:

• More noticeable papules or pustules
• Some redness and inflammation

Severe Acne:

• Deep, painful nodules or cysts
• High chance of permanent scarring
• Can affect self-esteem and mental health

6. Diagnosing Acne

Dermatologists typically make a diagnosis by simply examining the skin. No tests are usually required unless:

• Acne is severe or resistant to treatment
• There are signs of hormonal imbalance (especially in women)

They may check for conditions that look similar to acne, such as:

• Rosacea
• Folliculitis
• Perioral Dermatitis

7. Medical Treatment Options

Topical Treatments:

• Benzoyl Peroxide – Fights bacteria and helps dry out active acne
• Salicylic Acid – Helps clear clogged pores
• Retinoids – Encourage skin turnover and prevent new breakouts

Oral Medications:

• Antibiotics – Like doxycycline to reduce inflammation
• Hormonal Therapy – Birth control or spironolactone for hormonal acne
• Isotretinoin (Accutane) – A powerful drug for cystic or resistant acne

Professional Procedures:

• Chemical Peels – Remove dead skin and unclog pores
• Laser or Light Therapy – Targets bacteria and reduces inflammation
• Steroid Injections – Shrink large, painful cysts

8. Natural Remedies That Help

Evidence-Based Natural Options:

• Tea Tree Oil – Natural antibacterial properties (always dilute!)
• Aloe Vera Gel – Soothing and anti-inflammatory
• Green Tea Extract – Reduces oil and has antioxidant benefits

DIY Recipes:

• Honey + Cinnamon Mask – Both have antibacterial qualities
• Oatmeal Paste – Soothes skin and removes excess oil

Avoid These:

• Toothpaste (irritates and dries the skin)
• Lemon juice (too harsh and can cause burns)

9. Skincare Tips for Prevention

Morning Routine:

1. Gentle cleanser (non-foaming, fragrance-free)
2. Light, oil-free moisturizer
3. Sunscreen (at least SPF 30, non-comedogenic)

Night Routine:

1. Double cleanse if wearing makeup
2. Apply a retinoid (start slowly)
3. Use a calming moisturizer or serum

Lifestyle Habits:

• Wash pillowcases and phone screens regularly
• Avoid picking or squeezing pimples
• Stick to non-pore-clogging makeup and skincare

10. Diet & Lifestyle Connection

Foods That May Trigger Acne:

• Dairy products, especially skim milk
• High-glycemic foods (white bread, soda, sugary snacks)

Foods That May Help Clear Skin:

• Omega-3 fats (from fish, flaxseed, walnuts)
• Zinc-rich foods (pumpkin seeds, legumes)
• Antioxidant-rich vegetables and fruits

11. Scars and How to Treat Them

Types of Scarring:

• Atrophic – Indented scars (boxcar, ice-pick, rolling)
• Hypertrophic – Raised, firm scars

Treatment Options:

• Microneedling – Stimulates collagen and skin repair
• Laser Resurfacing – Smooths out textured skin
• Chemical Peels – Gradually fade marks and discoloration
• Fillers – Temporarily lift indented scars

12. Acne Myths Debunked
