Topical hyaluronic acid in creams and serums is generally regarded by health professionals as acceptable during pregnancy, mainly because it is a large molecule that is not expected to be absorbed into the bloodstream. Much of this comes from expert opinion rather than dedicated studies.
Injectable and oral forms
Safety of injected and oral hyaluronic acid has not been studied in pregnancy, so doctors generally advise avoiding them.

Hyaluronic acid products are often combined with other actives. Retinoids in particular are commonly avoided in pregnancy, so read labels and ask your midwife, doctor or pharmacist.
When in doubt
This is general information, not medical advice. Check with your healthcare provider about any skincare product you are unsure of.
