Hyaluronic acid
Hyaluronic acid is a naturally occurring substance in your body that is safe to use topically during pregnancy. It provides excellent hydration, plumps the skin, and helps combat pregnancy-related dryness without any known risks to your baby.
Why hyaluronic acid is treated as low risk
Despite the name, hyaluronic acid is not an exfoliating acid. It is a humectant — a large molecule that holds water against the skin. Your body already produces it, and the molecule is generally too large to pass meaningfully through the skin barrier, which is why topical use in pregnancy is widely regarded as low risk.
Where it helps in pregnancy
- Dryness and tightness, which many people notice for the first time in pregnancy.
- Supporting a compromised barrier when you have stopped using stronger actives.
- Layering under a moisturiser without adding irritation, which matters when skin is more reactive than usual.
What to check on the product
Hyaluronic acid is rarely sold alone. The question worth asking is what it is formulated with: a serum that pairs it with retinol or high-strength salicylic acid is not pregnancy-friendly because of the other ingredient, not the hyaluronic acid. Read the full list rather than the front of the bottle.
Injectable dermal fillers are a separate matter. Those are usually postponed until after pregnancy and breastfeeding, simply because they have not been studied in pregnancy rather than because of known harm.
How to apply it
Apply to damp skin and seal it with a moisturiser. On its own in a dry room, a humectant can draw water out of the skin rather than into it, which is the usual reason people find it makes their skin feel tighter.
Frequently asked questions
Is hyaluronic acid safe during pregnancy?
Topical hyaluronic acid is widely regarded as low risk in pregnancy. It is a humectant rather than an exfoliating acid, the body already produces it, and the molecule is generally too large to pass meaningfully through the skin barrier.
Are hyaluronic acid fillers safe in pregnancy?
Injectable fillers are usually postponed until after pregnancy and breastfeeding. That is because they have not been studied in pregnancy rather than because of known harm.
What should I check before using a hyaluronic acid serum while pregnant?
Check the rest of the ingredient list. Hyaluronic acid is often combined with retinol or high-strength salicylic acid, and it is those ingredients, not the hyaluronic acid, that make a product unsuitable.
How do I use hyaluronic acid without my skin feeling tighter?
Apply it to damp skin and seal it with a moisturiser. Used alone in dry air, a humectant can pull water out of the skin instead of holding it in.
