Which medication is the first-line treatment for acne in adolescents?

• A. Benzoyl peroxide
• B. Doxycycline
• C. Clindamycin
• D. Tretinoin

Answer: (A)

For adolescents with mild acne, the first step is a safe, effective topical therapy that tackles both bacteria on the skin and clogged pores. Benzoyl peroxide fits this role well: it directly reduces the acne-causing bacteria and helps prevent pore blockage, and it also has anti-inflammatory effects. It’s widely available, inexpensive, and has a favorable safety profile with minimal systemic absorption, making it ideal as a starting treatment in teens. An important advantage is that it lowers the risk of developing antibiotic resistance when used alongside other therapies, so it’s often used as the backbone of regimens that combine with topical antibiotics or retinoids. Doxycycline is an oral antibiotic reserved for more moderate to severe inflammatory acne or cases where systemic treatment is needed, and it carries systemic side effects and resistance concerns. Topical clindamycin is effective but can lead to resistance if used alone, which is why it’s typically paired with benzoyl peroxide rather than used as sole therapy. Tretinoin, a retinoid, is excellent for comedones and uses, but it can be irritating and is usually started in combination with benzoyl peroxide or after establishing tolerability, so it isn’t the sole first-line choice in many adolescent regimens.
