Treatment tiers
Min response time
Acne is the commonest skin condition globally and affects up to 85% of teenagers. It can persist or even start in adulthood, especially in women. Although it’s not dangerous, scarring and psychological impact make timely treatment important.
Treatment is tiered to severity. Mild acne responds to topical retinoids and benzoyl peroxide. Moderate acne adds topical antibiotics or short oral antibiotic courses. Severe or scarring acne — and acne that hasn’t responded after a fair trial — is treated with isotretinoin (Roaccutane), which is highly effective but needs careful monitoring.
Adapalene, tretinoin. Unclog pores and reduce inflammation. First-line for almost all acne. Apply nightly.
Doxycycline, lymecycline. Used for moderate acne for up to 3 months — never alone, always with a topical retinoid.
Oral vitamin A derivative. Often curative in severe acne. Strict monitoring; teratogenic — pregnancy must be excluded.
Allow at least 12 weeks. Most treatments cause an initial flare or dryness before improvement.
Consider it for severe or scarring acne, or moderate acne unresponsive to 3–6 months of standard treatment. It needs specialist supervision.
Diet plays a small role. High-glycaemic foods and dairy are weakly linked. Lifestyle alone rarely fixes acne.
