Glycolic Acid


Safe substance and/or breastfeeding is the best option.

Natural organic acid which is a part of alpha-hydroxy acids group or fruit acids (citric, lactic, malic and mandelic) with keratolytic and moisturizing properties on the skin.
Topically used for acne, psoriasis and pigmentation disorders.

At latest update relevant published data were not found on excretion into breast milk.

The small dose used and poor passage to plasma of most topical dermatological preparations make unlikely an excretion into breast milk in significant amounts.

It is very irritating. Do not apply it on the breast to prevent ingestion by the infant; otherwise, do it just after a meal and clean the nipple thoroughly with water before the next feed.


We do not have alternatives for Glycolic Acid since it is relatively safe.

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.

Thank you for helping to protect and promote breastfeeding.

José María Paricio, founder of e-lactancia.
