Prescription and OTC Acne Treatments: Topical, Oral, and Procedural Options

Acne treatment is tailored to severity, lesion type, and patient factors. A stepwise approach balances efficacy, side effects, and adherence.

Topical (First-Line for Mild–Moderate)

• Benzoyl peroxide (BP): Bactericidal vs C. acnes, anti-inflammatory; OTC 2.5–10%.
• Salicylic acid: Keratolytic, comedolytic; OTC 0.5–2%.
• Topical retinoids: Adapalene (OTC 0.1%), tretinoin, tazarotene (Rx)—normalize follicular keratinization, anti-inflammatory.
• Topical antibiotics: Clindamycin, erythromycin—always combine with BP to prevent resistance.
• Azelaic acid: Antimicrobial, anti-inflammatory, depigmenting; good for post-inflammatory hyperpigmentation (PIH).
• Dapsone gel: Anti-inflammatory, for inflammatory acne.

Oral (Moderate–Severe or Scarring)

• Oral antibiotics: Doxycycline, minocycline, sarecycline—limit to 3–4 months; combine with topical retinoid/BP.
• Hormonal therapy (females): Combined OCPs (estrogen/progestin), spironolactone (anti-androgen).
• Isotretinoin: Only drug targeting all pathogenic factors; for severe/nodular/scarring acne; requires iPLEDGE monitoring.

Procedural (Adjunctive)

• Chemical peels (glycolic, salicylic)
• Laser/light therapy (PDT, blue/red light)
• Intralesional corticosteroids (nodules/cysts)
• Comedone extraction
• Microneedling (for scarring)

Keys to Success

• Consistency: Most topicals take 8–12 weeks for visible improvement.
• Realistic expectations: Clearance, not perfection.
• Moisturize and sunscreen: Retinoids and BP cause dryness/photosensitivity.
• Follow-up: Adjust regimen based on response/tolerance.

Acne is a chronic condition, not a cosmetic flaw. Evidence-based, individualized treatment prevents scarring and improves quality of life.
