As already mentioned, the use of oral hyaluronic acid preparations is not recommended during pregnancy and breastfeeding. This recommendation applies because the effect of hyaluronic acid on the newborn has not yet been sufficiently researched.
However, the external application of a hyaluronic acid serum is usually safe and harmless. This applies to both pregnancy and breastfeeding. However, the serum should not be applied to the breast during breastfeeding.
