Sodium PCA, answered

Yes. Sodium PCA is considered safe to use during pregnancy and breastfeeding. As with anything, if you are unsure it is worth a quick word with your doctor or midwife.
Who should avoid Sodium PCA?
No specific group is flagged to avoid Sodium PCA. It is well tolerated by most skin. Still, introduce anything new one product at a time.
What concentration of Sodium PCA actually works?
Its concentration is rarely printed on the label, so use the ingredient list as your clue: near the top third it is likely doing real work, near the bottom it is more of a sprinkle.
