Acne Vulgaris: Causes, Symptoms & Treatment Guide

Overview

Acne vulgaris is a common chronic inflammatory skin condition affecting the pilosebaceous units, primarily on the face, chest, back, and shoulders. It is most prevalent among adolescents but can persist into adulthood. The condition ranges from mild comedones to severe nodulocystic lesions, causing physical discomfort and psychological distress. In India, acne affects nearly 85% of teenagers and young adults, with genetic predisposition, hormonal changes, and lifestyle factors playing significant roles.

Causes

Acne vulgaris results from four key pathogenic factors: (1) increased sebum production under androgen stimulation, (2) follicular hyperkeratinization leading to plugging, (3) colonization by Cutibacterium acnes bacteria, and (4) inflammation. Triggers include hormonal fluctuations during puberty, menstruation, pregnancy; stress; certain medications (corticosteroids, lithium); high-glycemic diets; dairy intake; and cosmetic products that clog pores. In Indian context, excessive heat and humidity, use of heavy oils, and poor hygiene can exacerbate acne.

Symptoms

Symptoms vary by severity: Non-inflammatory lesions include open comedones (blackheads) and closed comedones (whiteheads). Inflammatory lesions include papules (red, tender bumps), pustules (pus-filled lesions), nodules (large, painful lumps), and cysts (deep, pus-filled lesions). Post-inflammatory hyperpigmentation (dark spots) and scarring are common in Indian skin types. Patients may experience pain, tenderness, and psychological effects like low self-esteem.

Diagnosis

Diagnosis is primarily clinical, based on history and physical examination. Dermatologists grade acne severity: mild (few comedones, occasional papules), moderate (multiple papules/pustules, few nodules), severe (numerous nodules/cysts, scarring). No laboratory tests are routinely needed, but hormonal evaluation (serum testosterone, DHEAS) may be done in females with hirsutism or irregular menses to rule out polycystic ovary syndrome (PCOS). Skin swab cultures are reserved for suspected secondary infection.

Treatment Options

Topical Therapies

First-line for mild-to-moderate acne: benzoyl peroxide (2.5-10%), retinoids (tretinoin 0.025-0.1%, adapalene 0.1-0.3%), antibiotics (clindamycin 1%, erythromycin 2%), and salicylic acid. Combination products (e.g., adapalene+benzoyl peroxide) improve efficacy.

Systemic Therapies

For moderate-to-severe acne: oral antibiotics (doxycycline 100mg twice daily, minocycline, azithromycin), hormonal therapy (oral contraceptives, spironolactone for females), and isotretinoin (0.5-1 mg/kg/day for 16-24 weeks) for severe nodulocystic acne. All require prescription and monitoring.

Procedures

Comedone extraction, chemical peels (glycolic, salicylic), laser therapy, photodynamic therapy, and intralesional corticosteroid injections for large cysts.

Prevention

Preventive measures include: gentle cleansing twice daily with mild cleanser; avoiding harsh scrubbing; using non-comedogenic skincare products; maintaining a low-glycemic diet rich in fruits, vegetables, and omega-3 fatty acids; managing stress; avoiding picking or squeezing lesions; changing pillowcases regularly; and limiting dairy intake if sensitive. Sun protection is crucial to prevent post-inflammatory hyperpigmentation.

Ayurvedic Perspective & Remedies

In Ayurveda, acne (Yauvan Pidaka) is linked to vitiation of Pitta and Kapha doshas. Remedies include: Neem (antibacterial, anti-inflammatory) as paste or face wash; Turmeric (curcumin) for inflammation; Aloe vera gel for soothing; Triphala for internal detox; Manjistha blood purifier; and Guggulu for hormonal balance. Dietary advice: avoid spicy, oily, and fermented foods; drink warm water; include bitter vegetables (karela, methi). Panchakarma therapies like Virechana (purgation) may be recommended. Always consult an Ayurvedic practitioner before use.
