Salicylic Acid 0.5%
Low risk
Salicylic acid is a beta-hydroxy acid (BHA) used for acne, exfoliation and preservation. Common over-the-counter acne strengths are 0.5-2%, including 0.5%, 1% and 2%; the FDA lists this acne-treatment range. Pregnancy guidance distinguishes these topical products from oral salicylates and strong peels. MotherToBaby reports that ACOG allows over-the-counter topical salicylic acid during pregnancy when needed. Only a small amount of topical acne treatment usually reaches the bloodstream through intact skin; exposure can increase with damaged skin, frequent use or treatment of large areas. Direct salicylic-acid-specific pregnancy data remain limited. MamaSkin's Low Risk rating is a dose-and-use precaution, not evidence that ordinary low-strength skincare causes fetal harm or a recommendation to avoid every BHA product. Use as directed on limited areas of intact skin. Discuss strengths above 2%, chemical peels, wart/corn removers, large-area treatment or use under occlusion with your clinician before use during pregnancy. The American Academy of Dermatology specifically advises discussing and limiting higher-strength salicylic acid above 2%. Percentage alone does not establish safety: formulation, area, frequency and skin condition also matter. General cosmetic-use limits are not pregnancy-specific safety thresholds.

Questions about this assessment
Why does Paula's Choice 0.5% BHA Liquid Exfoliant have a Low risk rating?
The recorded formula includes 1 ingredient entry with a risk flag: Salicylic Acid 0.5% (Low risk). These are ingredient-level flags; they do not replace the stored product assessment or account for every formulation detail. The product score is a stored assessment, not a clinical safety guarantee.
Has every ingredient in Paula's Choice 0.5% BHA Liquid Exfoliant been assessed?
8 of 8 ingredient entries on this page have a recorded score, evidence summary and source text. That describes documentation coverage, not proof that the finished formula has been clinically tested during pregnancy.
Does this assessment apply to my Paula's Choice 0.5% BHA Liquid Exfoliant?
Only if the ingredient list on your packaging matches the recorded formula shown here. Formulas can differ by market and change over time. Compare the full list, not just the product name; report a mismatch if it differs.
Does this pregnancy assessment also establish breastfeeding suitability?
No. This page presents a pregnancy-focused product assessment. Do not infer a breastfeeding conclusion from its score or label; breastfeeding requires a separate assessment of the formula and how it is used.
