Question: is bha and aha safe for pregnancy?
Answer: Now, Alpha Hydroxy Acids (AHAs) and Beta Hydroxy Acids (BHAs) are a bit trickier to navigate during pregnancy. Salicylic acid is a BHA, so best to avoid it. Glycolic acid, which is an AHA, is considered safe to use in lower concentrations, but you can always use a product containing lactic acid instead.
