Acne
Acne (Acne Vulgaris) is a chronic skin condition that occurs when pores (hair follicles) become blocked by oil (sebum), dead skin cells, and bacteria. It causes various types of blemishes like pimples, blackheads, whiteheads, nodules, and cysts.
It most commonly appears on the face, back, chest, and shoulders—areas with the most oil (sebaceous) glands.

🔍 Causes of Acne
1. Excess Sebum Production
Hormonal changes (like puberty, menstruation, or pregnancy) increase oil production, making the skin more prone to clogging.
2. Clogged Hair Follicles
Dead skin cells and oil block the pores, trapping bacteria inside.
3. Bacterial Infection
Cutibacterium acnes (formerly Propionibacterium acnes) bacteria multiply in clogged pores, causing inflammation and pus.
4. Hormonal Changes
Androgens (male hormones present in both sexes) increase oil production. Hormonal imbalances in PCOS, stress, or certain medications can trigger or worsen acne.
5. Other Contributing Factors
Genetics (family history)
Diet (high glycemic index foods, dairy in some people)
Stress
Heavy makeup or greasy skincare
Sweating, humidity, or tight clothing

💊 Treatment Options for Acne
Acne treatments depend on severity, type, and skin sensitivity. Treatments can be topical, oral, procedural, or a combination.
🔹 1. Topical Treatments (Applied to Skin)
✅ Best for mild to moderate acne
a. Benzoyl Peroxide
Kills acne-causing bacteria
Reduces inflammation
Commonly used in gels, cleansers, and creams
b. Salicylic Acid
Helps exfoliate and unclog pores
Often used in face washes and toners
c. Topical Retinoids (e.g., Adapalene, Tretinoin)
Promote cell turnover, prevent clogged pores
May initially cause dryness or irritation
d. Topical Antibiotics (e.g., Clindamycin, Erythromycin)
Reduce bacteria and inflammation
Often combined with benzoyl peroxide to prevent resistance
🔹 2. Oral Medications
✅ Best for moderate to severe or hormonal acne
a. Antibiotics (e.g., Doxycycline, Minocycline)
Reduce inflammation and bacterial growth
Used for short-term periods (to prevent resistance)
b. Hormonal Therapy (for women)
Birth control pills: Regulate hormones that trigger excess oil
Spironolactone: Blocks androgens, reduces oil production
c. Isotretinoin (Accutane)
A powerful oral retinoid for severe, scarring, or resistant acne
Shrinks oil glands permanently
Requires careful monitoring (can cause side effects and birth defects)
🔹 3. Professional or In-Clinic Treatments
a. Chemical Peels
Use acids (like salicylic, glycolic, or TCA) to exfoliate and unclog pores
Good for comedonal acne and post-acne marks
b. Laser & Light Therapy
Kills bacteria and reduces oil production
Can help reduce inflammation and scarring
c. Microneedling
Improves skin texture and acne scarring
d. Extraction
Manual removal of blackheads and whiteheads by a dermatologist or trained esthetician
e. Corticosteroid Injections
For large, painful nodules or cysts to reduce swelling quickly
🧴 Skincare for Acne-Prone Skin
Use a gentle cleanser twice daily
Avoid scrubbing or using harsh products
Choose non-comedogenic (won’t clog pores) moisturizers and sunscreens
Avoid touching or popping pimples
Remove makeup before bed
Use oil-free, fragrance-free products
