Can I use salicylic acid while pregnant?

Q: Can I use salicylic acid while pregnant?

Yes, in the concentrations found in ordinary over-the-counter cleansers and serums, which is around 2 percent or less. ACOG has indicated that over-the-counter topical salicylic acid can be used in pregnancy if needed. The caution you have read about applies to high-strength professional peels and to oral salicylates such as aspirin, which are a different exposure.

This question gets a confusing answer online because three different exposures share one name.

A cleanser or serum at 2 percent or less. This is what almost everyone means when they ask. Guidance from ACOG has indicated that over-the-counter topical products containing salicylic acid can be used during pregnancy if needed, and MotherToBaby’s guidance on topical acne treatments lands in the same place. The amount absorbed through skin from a small area at low strength is far below what a low-dose aspirin tablet delivers.

A professional peel at 20 to 30 percent. A genuinely different exposure, over a much larger area, at ten times the strength. This is where the caution is proportionate, and it is worth raising with whoever would be performing it.

Aspirin and other oral salicylates. A systemic dose taken by mouth. High-dose aspirin in pregnancy, particularly in the third trimester, is avoided for real reasons. Low-dose aspirin is sometimes actively prescribed in pregnancy for specific reasons, which is a decision for your clinician and not for a face wash.

Advice written about the third case gets repeated as though it covered the first. That is the whole confusion.
