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.
