What I'm seeing
The photo shows moderate-to-moderately-severe inflammatory acne on the cheek — multiple erythematous papules and pustules with surrounding redness, plus what looks like a hydrocolloid patch/spot cream already applied to a couple of lesions. This pattern (more inflammatory than comedonal, worse than a typical pre-pregnancy breakout) is classic for pregnancy-related acne, which flares because of rising maternal androgen levels — patients with a prior acne history are especially prone to this - Fitzpatrick's Dermatology, p. 1441.
Because several lesions look deep/pustular rather than just blackheads, I'd loop in your OB-GYN or a dermatologist before adding anything prescription-strength — but here is a safe, evidence-based routine you can start now.
Why certain ingredients are off-limits
Pregnant/lactating women are excluded from most drug trials, so safety data comes mainly from animal and observational studies. The general rule: topical agents are preferred over oral drugs because systemic absorption is much lower - Fitzpatrick's Dermatology, p. 1441. Per that textbook's safety table and the 2023-2024 clinical reviews below, here's the breakdown:
Safe / preferred
- Azelaic acid (Category B) - antimicrobial, comedolytic, mildly anti-inflammatory; considered one of the safest actives in pregnancy
- Topical clindamycin or erythromycin (Category B)
- Benzoyl peroxide (Category C, but low systemic absorption) - generally accepted in limited amounts, ideally with your OB's sign-off
- Topical sulfacetamide, azelaic acid combinations
- Glycolic acid / mild AHAs - gentle exfoliation, fine in pregnancy
- Niacinamide - anti-inflammatory, safe
Avoid
- Oral isotretinoin (Category X) - and topical tazarotene (Category X)
- Tretinoin/other retinoids and retinol - "consider avoiding" per Fitzpatrick's; teratogenic concern with oral retinoids
- Oral tetracyclines/doxycycline (Category D) - affect fetal bone/teeth
- Spironolactone - anti-androgen, contraindicated (feminizes male fetus)
- Salicylic acid in high concentrations or leave-on/oral form (occasional low-strength face wash use is usually tolerated, but many clinicians still prefer avoiding it)
- Hormonal/OCP-based acne treatment - not applicable in pregnancy anyway
(Table 78-5, Safety Ratings of Acne Medications in Pregnancy - Fitzpatrick's Dermatology, p. 1441)
Suggested daily routine
Morning
- Gentle, sulfate-free cleanser - e.g. CeraVe Hydrating Facial Cleanser or La Roche-Posay Toleriane Hydrating Gentle Cleanser (avoid harsh foaming/salicylic scrubs on inflamed skin)
- Azelaic acid 10-15% - e.g. The Ordinary Azelaic Acid Suspension 10%, or a prescription 15-20% (Finacea/Azelex) if your derm prescribes it - apply thin layer to acne-prone areas
- Lightweight, non-comedogenic moisturizer - e.g. CeraVe PM or Neutrogena Hydro Boost Gel
- Mineral sunscreen SPF 30+ (zinc oxide/titanium dioxide) - e.g. La Roche-Posay Anthelios Mineral or EltaMD UV Clear - pregnancy hormones make skin more prone to pigmentation, and inflamed acne marks darker without SPF
Evening
- Same gentle cleanser (double cleanse if wearing makeup/sunscreen)
- Benzoyl peroxide 2.5-5% spot treatment on active pustules only (thin layer, not whole face) - discuss frequency with your OB first, e.g. PanOxyl 4% Foaming Wash used as a 1-2 minute contact spot wash, or a low-strength cream
- On non-BP nights, alternate with azelaic acid again or a niacinamide serum (e.g. The Ordinary Niacinamide 10% + Zinc) to calm redness
- Moisturizer to finish
1-2x/week
- Gentle glycolic acid product (e.g. Biopelle or a similar mild AHA) for light exfoliation - skip if skin is already very irritated
Things that will help alongside the routine
- Don't pick/pop lesions - with skin this inflamed, picking risks scarring and post-inflammatory hyperpigmentation, which is already more likely in pregnancy due to hormonal pigment changes.
- Switch to non-comedogenic, oil-free makeup and pillowcase changes 2x/week.
- Avoid harsh physical scrubs - they worsen inflammatory acne.
When to escalate beyond OTC
Given the number of pustules and erythema in the photo, if this doesn't improve in 4-6 weeks or lesions become painful/cystic, ask your OB to refer you to dermatology. Pregnancy-compatible prescription options they may consider include topical clindamycin/erythromycin, or in more severe cases oral cephalexin, amoxicillin, or azithromycin (all Category B) - never tetracyclines/doxycycline - Fitzpatrick's Dermatology, p. 1441; also corroborated by recent reviews:
Management of Acne in Pregnancy (2024) and
Treatment of Acne Vulgaris During Pregnancy and Lactation (2023), both of which reinforce azelaic acid, topical/oral erythromycin, and topical clindamycin as first-line, with retinoids and oral tetracyclines/isotretinoin contraindicated.
One practical note: if you're currently using any acne spot patches (the pale circles visible in your photo), hydrocolloid patches themselves are totally pregnancy-safe - just check the underlying gel/serum ingredient if it's a medicated patch.
