Acne Treatment: What Actually Works

Acne is the most common skin condition in the United States, affecting up to 50 million Americans annually. It can occur at any age, though it's most prevalent in teenagers and young adults.

Understanding Acne Types

Non-inflammatory (comedonal):

• Whiteheads (closed comedones): pores clogged with oil and dead skin
• Blackheads (open comedones): same as whiteheads but open to air, causing oxidation

Inflammatory:

• Papules: small, raised red bumps
• Pustules: papules with visible pus
• Nodules: large, solid, painful lumps deep in the skin
• Cysts: painful, pus-filled lumps that can cause scarring

Evidence-Based Treatments

Over-the-Counter (OTC)

Benzoyl Peroxide (2.5–10%)

Kills acne-causing bacteria (C. acnes) and reduces inflammation. Available in washes, gels, and spot treatments. Start with lower concentrations to minimize irritation.

Salicylic Acid (0.5–2%)

Helps unclog pores by dissolving the bonds between dead skin cells. Best for blackheads and whiteheads.

Adapalene 0.1% (Differin)

A retinoid now available OTC. Prevents new comedones from forming and reduces inflammation. Apply at night; use sunscreen during the day.

Prescription

Topical retinoids (tretinoin, tazarotene): Most effective for comedonal acne; require prescription

Topical antibiotics (clindamycin, erythromycin): Reduce bacteria; always combined with benzoyl peroxide to prevent resistance

Oral antibiotics (doxycycline, minocycline): For moderate-to-severe inflammatory acne; short-term use

Oral isotretinoin (Accutane): For severe, scarring, or treatment-resistant acne; requires close medical supervision

What Doesn't Work

• Toothpaste (irritates skin)
• Popping pimples (spreads bacteria, causes scarring)
• Harsh scrubbing (worsens inflammation)
• Eliminating all dairy or chocolate (evidence is weak and highly individual)

See a board-certified dermatologist if OTC treatments haven't worked after 2–3 months.
