PABA or paraaminobenzoic acid is a substance that should be avoided in photoprotective products for pregnant women and women who are breastfeeding, as well as in children. It is a common component in sun blockers, an acid that although sometimes called vitamin Bx, is not a true vitamin.
Despite being a substance with different beneficial properties for skin and hair, research on it is still ongoing, and it seems that many studies on PABA are old and would need revision and updating. There is even controversy over whether it is beneficial or harmful to treat certain skin diseases.
However, in different documents that I have been able to access about this substance, its use is not recommended in pregnancy or during breastfeeding, nor for the first months of the baby's life.
PABA should be avoided to prevent possible allergic skin reactions. Overdose of this substance (which is present in very low doses in certain foods, especially meats and cereals) could cause hypoglycemia, hives, intestinal problems and even liver toxicity, especially in infants.
In different nutritional complexes that are marketed under that name, "PABA", it is noted as contraindicated for pregnant women and infants, or it is warned that you have to consult the doctor before taking the product.
Therefore, it is advisable not to use protectors that contain this substance that is so questioned and that could be harmful in high doses.
