This sounds most consistent with acne vulgaris, but the plan depends on whether lesions are mainly blackheads/whiteheads, red pus-filled pimples, or deep painful lumps.
Initial management for mild acne
Use treatment consistently for 8 to 12 weeks before judging the response.
Morning
- Wash gently with a mild cleanser. Do not scrub.
- Apply benzoyl peroxide 2.5% to 5% thinly to acne-prone areas, not just individual pimples. It reduces acne bacteria and inflammation. It can dry the skin and bleach towels/clothing.
- Non-comedogenic moisturizer and sunscreen SPF 30+.
Night
- Gentle cleanser.
- Apply a pea-sized amount of adapalene 0.1% gel over the whole acne-prone facial area, initially 2 to 3 nights/week, then nightly as tolerated.
- Use moisturizer if dryness or peeling occurs.
Topical retinoids such as adapalene reduce blocked pores and inflammation. Benzoyl peroxide plus a topical retinoid is a standard first approach for mild acne.
Textbook of Family Medicine, p. 925. The current
AAD acne guidance also supports using combinations of topical agents rather than a single treatment alone.
If there are many inflamed red pimples or pustules
A clinician may prescribe
clindamycin 1% with benzoyl peroxide, often alongside adapalene. Do
not use topical clindamycin alone because it encourages antibiotic resistance. The
AAD recommendations specifically advise pairing topical or oral antibiotics with benzoyl peroxide.
If moderate, painful, widespread, or leaving scars
She should see a dermatologist or primary-care clinician. Treatment may require:
- A limited course of an oral antibiotic such as doxycycline, together with benzoyl peroxide and a topical retinoid
- In women with persistent hormonal-pattern acne, consideration of a combined oral contraceptive or spironolactone after an individual assessment
- Isotretinoin only under dermatology supervision for severe nodular acne, scarring acne, or failure of standard treatments. It causes serious birth defects and requires strict pregnancy prevention and monitoring. Textbook of Family Medicine, p. 925.
Important advice
- Do not squeeze or pick lesions, as this increases marks and scarring.
- Choose makeup, sunscreen, and moisturizer labelled non-comedogenic or oil-free.
- Avoid harsh scrubs, alcohol-based toners, and frequent face washing.
- Acne may briefly seem worse in the first few weeks after starting adapalene.
- Do not use adapalene, tretinoin, tazarotene, spironolactone, doxycycline, or isotretinoin in pregnancy. Check pregnancy status and use reliable contraception where relevant before any prescription treatment.
Assess for an underlying hormonal issue
Ask about irregular or absent periods, new facial/body hair growth, scalp hair thinning, rapid weight gain, or darkened skin in body folds. Acne with these features can suggest PCOS or another androgen-excess condition and needs medical assessment. Female patients with resistant acne plus irregular cycles, hirsutism, or obesity should be evaluated for androgen excess, including PCOS. Fitzpatrick’s Dermatology, acne and the adolescent section.
See a clinician promptly if she has deep painful nodules/cysts, facial swelling, fever, rapid scarring, or major distress about her appearance.
Recent evidence: a 2024 systematic review supports several combination options for moderate-to-severe acne, but the appropriate choice still depends on lesion severity and tolerability (PMID: 38564399).
