Pregnancy-safe skincare checker by trimester.

The clear no-go list (entire pregnancy)

Strong consensus across ACOG (American), UK Teratology Information Service, and Australian NDPSC:

• All topical retinoids — tretinoin (Retin-A), adapalene (Differin OTC), tazarotene. The teratogenic risk evidence is strongest for oral retinoids, but topical retinoids carry enough systemic absorption that all major guidelines list them as contraindicated.
• Oral retinoids — isotretinoin (Accutane), acitretin. Absolute contraindication. Severe teratogenic risk.
• Hydroquinone — used for hyperpigmentation. 35-45% systemic absorption when applied topically. Off-limits during pregnancy and breastfeeding per most guidelines.
• Salicylic acid above 2%, including high-strength chemical peels and body washes with concentrated BHA. Low-strength facial cleansers (under 2%) are generally considered acceptable but skip in the first trimester to be conservative.
• Oral tetracyclines (doxycycline, minocycline) — commonly prescribed for rosacea and acne. Off-limits for the duration of pregnancy and breastfeeding due to fetal/infant bone development risk.
• Hydrocortisone above 1% long-term or on large body areas. Brief use on small areas is acceptable.
• Topical minoxidil (for hair loss). Off-limits.

The yes-go list (pregnancy-safe alternatives)

• Azelaic acid 10-20% — the workhorse pregnancy active. Anti-acne, anti-rosacea, anti-PIH, anti-melasma. Naturally produced by skin yeast, minimal systemic absorption. See our AzA finder.
• Niacinamide 5% — anti-inflammatory, brightening, oil control. Safe throughout pregnancy and breastfeeding.
• Glycolic acid 5-10% — at low concentrations, acceptable per ACOG guidance. Higher percentages (15%+ professional peels) skip.
• Lactic acid 5-10% — same low-concentration rule as glycolic.
• Hyaluronic acid — completely safe. Hydration baseline.
• Vitamin C (L-ascorbic acid, MAP, SAP) — safe throughout. Useful for melasma + general brightness when retinoids are off-limits.
• Ceramides, peptides — safe, hydrating, barrier-supportive.
• Sunscreens — mineral (zinc oxide, titanium dioxide) recommended. Chemical filters are generally considered safe but several pregnant patients prefer mineral.
• Benzoyl peroxide 2.5-5% — generally considered acceptable in spot treatment for acne. Some practitioners advise pausing in the first trimester out of conservatism.
• Tranexamic acid topical — emerging evidence supports safety, particularly useful for pregnancy-onset melasma.

The conditional / trimester-specific list

Some actives are acceptable in some trimesters but not others, or in some doses but not others. This is where most online lists oversimplify.

First trimester (weeks 1-12)

The highest sensitivity period — fetal organ formation. Most conservative approach: pause anything ambiguous. Salicylic acid even at 2% in cleansers, low-strength AHAs, and benzoyl peroxide all get paused by some practitioners in this trimester. Default to: cleanser, moisturizer, sunscreen, and azelaic acid if needed for acne or pigmentation.

Second trimester (weeks 13-27)

Lower sensitivity window. Most of the "yes-go" list expands. Mild AHA peels (under 30%) are sometimes considered acceptable. Most pregnancy-onset melasma protocols start here, using azelaic acid + niacinamide + tranexamic acid + sunscreen.

Third trimester (weeks 28-40)

Similar to second. The main consideration: anything that would be problematic for the newborn if absorbed pre-delivery should be tapered before delivery. Most topical skincare is fine throughout, but heavy systemic actives (oral antibiotics including tetracyclines) should be wound down per the OB\'s instructions.

Breastfeeding considerations

Most pregnancy-safe topicals remain safe during breastfeeding. The main additions to the no-go list during nursing:

• Retinoids — still off-limits during breastfeeding due to systemic absorption
• Hydroquinone — still off-limits
• Tetracyclines — off-limits during nursing of infants under 8
• High-strength salicylic acid — pause during nursing
• Topical steroids — avoid application to chest/breast area before nursing sessions

Common pregnancy skin concerns and what to use

Pregnancy melasma ("chloasma" or "mask of pregnancy")

The pattern of brown patches on the cheeks, forehead, and upper lip during pregnancy. Triggered by estrogen + progesterone + sun exposure. Treatment during pregnancy: azelaic acid + tranexamic acid + niacinamide + daily mineral SPF 30+ with iron oxides. Most cases improve postpartum, but daily SPF + iron-oxide-tinted protection is critical because visible light is a major trigger.

Pregnancy acne

Common in the first and second trimesters. Treatment: azelaic acid 10-20% + low-strength glycolic in cleanser + non-comedogenic moisturizer + mineral SPF. Skip benzoyl peroxide in the first trimester if conservative; otherwise spot treatment is acceptable. Severe cases that warrant oral treatment in non-pregnant patients require OB + dermatology coordination — sometimes oral erythromycin is used cautiously.

Stretch marks (striae gravidarum)

Honest answer: no topical reliably prevents or treats stretch marks. The genetic component is dominant. Daily moisturization may marginally help skin elasticity. Tretinoin works on existing stretch marks (post-pregnancy only). Cocoa butter is a popular hope, with no real evidence of efficacy.

Itchy belly / pregnancy itching

Common from skin stretching. Treatment: heavy ceramide moisturizers, oatmeal-based balms. If itching is severe, generalized, or worst on palms/soles, see your OB — it could be intrahepatic cholestasis of pregnancy, which needs medical management.
