A dermatology-backed guide to skincare ingredients during pregnancy: what's safe to use, what to avoid, and what to discuss with your doctor.

Most everyday skincare ingredients are fine to keep using during pregnancy. A handful, including topical retinoids, high-dose salicylic acid, and certain chemical sunscreen filters, carry enough concern that most clinicians recommend pausing them. This article groups common ingredients into three categories, but always confirm your specific routine with your doctor, midwife, or OB-GYN.

What makes a skincare ingredient unsafe during pregnancy?

Medical disclaimer: This article is educational only, not medical advice. Safety profiles can shift by trimester and individual context. Discuss your full routine with your healthcare provider.

The concern is systemic absorption: an ingredient applied to skin can, in some cases, reach the bloodstream and cross the placenta. The risk depends on the molecule's size, concentration, the area of skin covered, and whether it's rinsed off or left on.

For most cosmetic actives applied in small amounts to a limited area, systemic exposure is very low. The ingredients flagged as high-risk are those where animal or human data shows teratogenic potential, or where the mechanism of action raises concern even without direct evidence. Dose, formulation, and trimester all matter when a clinician weighs the evidence.

Which ingredients are considered safe during pregnancy?

Several well-studied ingredients carry a strong safety record across all trimesters, based on clinical reviews.

Azelaic acid (typically 15-20%) is a first-line recommendation for acne and melasma during pregnancy. Systemic absorption is around 4% after a single application, and animal studies show no teratogenic potential at therapeutic doses 1.

Niacinamide has no documented pregnancy risk. It is water-soluble, well-tolerated, and does not penetrate deeply enough to raise concerns.

Hyaluronic acid is a large molecule with negligible systemic absorption. It is considered safe at any stage of pregnancy.

Vitamin C (L-ascorbic acid) is water-soluble, rapidly metabolized, and has no documented fetal risk.

Benzoyl peroxide up to 5% is listed as an acceptable option for mild acne in pregnancy by most dermatology guidelines, though some practitioners prefer to limit it to brief rinse-off formulations 1.

Glycolic and lactic acids (AHAs at typical leave-on concentrations) are generally considered safe. Professional peels at higher concentrations warrant more caution 2.

Which ingredients should you avoid during pregnancy?

Ingredient Category Why to avoid
Isotretinoin (oral) Avoid Well-established teratogen; causes birth defects in 20-35% of exposed pregnancies 1
Topical retinoids (tretinoin, adapalene, tazarotene) Avoid as precaution Systemic retinoids are known teratogens; topical data is reassuring but precautionary avoidance is standard 3
Salicylic acid peels / high-dose BHA Avoid High-concentration peels carry risk of significant systemic absorption 2
Hydroquinone Avoid High systemic absorption (35-45%) reported; avoid during pregnancy 1
Oxybenzone (chemical sunscreen) Avoid Detected in cord blood; some clinicians recommend switching to mineral filters during pregnancy
Formaldehyde-releasing preservatives Avoid Classified as potential carcinogens; low risk but no benefit to retaining them

Oral isotretinoin carries a 20-35% risk of major birth defects with first-trimester exposure and is strictly contraindicated throughout pregnancy 1. Topical retinoids are in a different category. A large Nordic cohort study following 3.8 million births found that 3.3% of infants exposed to topical retinoids in the first trimester had a major congenital malformation, compared with 3.0% in unexposed infants, a difference that was not statistically significant 3. Even with this reassuring data, standard clinical guidance remains to avoid topical retinoids as a precaution.

Salicylic acid: the ingredient most people ask about

Low-concentration salicylic acid, up to 2% in a rinse-off cleanser or toner, is generally considered acceptable during pregnancy. At that concentration and application pattern, systemic exposure is low enough that most dermatologists consider it a reasonable option for mild acne 1 4.

The concern kicks in at higher concentrations used for longer contact times. Salicylic acid peels (20-30%) applied to large skin areas are flagged in clinical reviews of cosmetic procedures during pregnancy, because systemic absorption scales significantly with concentration and leave-on time 2.

The practical guidance: a 0.5-2% salicylic acid cleanser washed off after 30 seconds is a very different risk profile from a 20% peel left on for several minutes. If your routine includes both, the former is likely fine to continue; the latter warrants a conversation with your provider.

Which ingredients fall in the discuss-with-your-doctor zone?

Some ingredients have limited pregnancy-specific data but a plausible safety mechanism, or the evidence is mixed enough that the answer depends on your individual situation.

Topical retinoids (discussed above): emerging evidence is reassuring, but precautionary avoidance is still the standard recommendation 3.

Benzoyl peroxide above 5%: generally considered safe, but high concentrations over large areas fall in the discuss category.

Kojic acid: limited human pregnancy data exists. Some practitioners are comfortable with it; others prefer azelaic acid as the established alternative for hyperpigmentation.

Certain essential oils (camphor, rosemary at high doses): minimal safety data and some concern about uterine stimulation. Amounts in skincare products are typically low, but worth mentioning to your provider if they feature prominently in your routine.

Sunscreen with mineral filters (zinc oxide, titanium dioxide) is widely recommended as the safest choice during pregnancy. These filters sit on the skin surface and have minimal systemic absorption. If you're currently using an oxybenzone-based sunscreen, switching to a mineral option is a straightforward swap most providers would support without hesitation.

FAQ

Is salicylic acid safe during pregnancy?

Low concentrations, up to 2% in a rinse-off product, are generally considered acceptable. High-concentration salicylic acid peels should be avoided. Confirm the products you're using with your healthcare provider.

Can I keep using my vitamin C serum while pregnant?

Yes. L-ascorbic acid is water-soluble, well-tolerated, and has no documented fetal risk. It is one of the safest actives to continue using throughout pregnancy.

What sunscreen should I use during pregnancy?

Mineral sunscreens containing zinc oxide or titanium dioxide are the widely recommended choice. They sit on the skin surface with minimal systemic absorption, and they provide broad-spectrum protection. Look for SPF 30 or higher and reapply every 2 hours outdoors.

Are retinoid face creams safe if I was using them before I knew I was pregnant?

Based on a 2026 Nordic study of 3.8 million births, inadvertent first-trimester topical retinoid exposure did not show a statistically significant increase in major congenital malformations 3. If this describes your situation, speak with your OB-GYN or midwife, who can review your exposure and provide reassurance based on your specific circumstances.

Do I need to change my whole routine when pregnant?

Not necessarily. Many everyday ingredients, including hyaluronic acid, niacinamide, azelaic acid, vitamin C, and mineral sunscreen, are compatible with pregnancy. The main swaps most practitioners recommend are stopping topical retinoids, replacing high-dose salicylic acid products, and switching to a mineral sunscreen if you're using a chemical filter.
