Is glycolic acid safe during pregnancy and breastfeeding?
Pregnancy references disagree on glycolic acid. MotherToBaby (2026) says OTC products containing glycolic acid may be used during pregnancy if needed, and a 2011 review found only a minimal amount is absorbed. InfantRisk (2020) advised avoiding it until more research is done. Everyday low-strength products and professional peels are not the same thing — ask before a peel.
Also listed on labels as: glycolic acid, AHA, alpha hydroxy acid.
Glycolic acid by stage
Trying to conceive
Depends on how it's used while trying to conceiveThere is no specific preconception guidance. Because pregnancy can start before a test shows it, the pregnancy picture applies — everyday OTC products are allowed by MotherToBaby; ask before high-strength peels. [1][3]
Pregnant
Depends on how it's used during pregnancyMotherToBaby says OTC glycolic acid products may be used during pregnancy if needed, and a 2011 review found only a minimal amount is absorbed. InfantRisk advised avoiding it until more research is done. The strength and type of product matter — ask before professional peels. [1][2][3]
Breastfeeding
No concern found while breastfeedingThe amount of topical acne treatments that passes into breast milk is likely to be low. Do not apply it to the nipple or areola, and wash it off before breastfeeding if it is on nearby skin. [1]
Postpartum
No concern found postpartumThe pregnancy caution is about a developing baby. If you are not pregnant, not breastfeeding and not trying to conceive, it no longer applies. [1]
What it is
Glycolic acid is an alpha hydroxy acid (AHA) that exfoliates the top layer of skin. It is in toners, serums, masks and at-home “peel” pads, and at much higher strength in professional chemical peels.
Why we say “depends”
This is one of the ingredients where good sources don’t agree. The most recent MotherToBaby fact sheet (2026) allows OTC products if needed; InfantRisk’s 2020 overview preferred avoiding it until more research exists. We would rather show you the disagreement than pick a side and call it settled. Strength matters: an everyday toner and an in-clinic peel are very different exposures.
Practical tips
- Check the percentage — at-home peel pads can be much stronger than a daily toner.
- Ask your doctor, midwife or dermatologist before a professional peel.
- While breastfeeding, keep it off the nipple and areola.

MotherToBaby says OTC glycolic acid products may be used during pregnancy if needed, but InfantRisk advised avoiding it until more research is done. Low-strength everyday products and professional peels are different — ask your healthcare provider before a peel.
Can I use glycolic acid while breastfeeding?
Very little of a topical acne treatment is expected to pass into breast milk. Keep it off the nipple and areola.
