Is Hyaluronic Acid Safe During Pregnancy? Everything You Need to Know
Can you use hyaluronic acid during pregnancy? See what science says about the safety of this ingredient and its different forms for moms-to-be. Facts, no fear.
What is hyaluronic acid and how does it work?
Hyaluronic acid (INCI: Sodium Hyaluronate, Hyaluronic Acid) is a natural polysaccharide found in human skin, joints and connective tissue. Its main property is its ability to bind water — a single molecule can hold up to a thousand times its own weight in water. In cosmetics, it's used primarily as a moisturizing and smoothing agent.
In skincare products, hyaluronic acid comes in several forms: low molecular weight (penetrates deeper into the skin), high molecular weight (works on the surface as an occlusive film) and the cross-linked form, used exclusively in aesthetic medicine procedures — not in skincare cosmetics. You'll find a detailed breakdown of the differences between these forms in our ingredient encyclopedia.
Does hyaluronic acid penetrate the skin and enter the body?
This is the key question when we talk about the safety of cosmetic ingredients during pregnancy. Under the current EU Regulation 1223/2009 on cosmetic products, every ingredient placed on the market must meet a safety standard — and assessing transdermal absorption is part of that evaluation.
High molecular weight hyaluronic acid (molar mass above 1 million Da) does not penetrate the skin barrier — the molecules are simply too large. Low molecular weight forms (below 50 kDa) can penetrate more deeply, but studies have not shown systemic absorption following topical application at cosmetic concentrations. The SCCS (Scientific Committee on Consumer Safety) has issued no warnings regarding the use of hyaluronic acid in cosmetics by pregnant women.
Hyaluronic acid in pregnancy — what do the experts say?
Dermatologists and gynecologists agree that hyaluronic acid is one of the safest skincare ingredients during pregnancy. It has no teratogenic effects, doesn't disrupt hormonal balance and doesn't accumulate in the body. This matters especially because a pregnant woman's skin often becomes dry, sensitive and prone to irritation.
- Safe: Sodium Hyaluronate and Hyaluronic Acid in both leave-on and rinse-off products.
- Safe: Hydrolyzed Hyaluronic Acid (hydrolysis fragments).
- Only under medical supervision: Aesthetic medicine procedures using cross-linked HA — these are not cosmetics and should be avoided during pregnancy.

What to look for when choosing a hyaluronic acid serum during pregnancy
Hyaluronic acid itself is safe, but a cosmetic product is always about the full formula, not a single ingredient. During pregnancy, it's worth avoiding products that also contain:
- Retinol and other retinoids (vitamin A and its derivatives),
- Salicylic acid at concentrations above 2% in leave-on products,
- Formaldehyde-releasing preservatives (e.g. DMDM Hydantoin),
- High concentrations of essential oils.
It's worth reading the label or checking the formula with our Check Your Cosmetic's Ingredients tool — PurScore.pl automatically flags ingredients that may be problematic during pregnancy.
Hyaluronic acid and breastfeeding
The same principle applies during lactation. When applied topically, hyaluronic acid does not pass into breast milk in clinically relevant amounts. Neither the American Academy of Dermatology nor most European dermatological societies include it on their lists of ingredients to avoid while breastfeeding.
How to use hyaluronic acid during pregnancy — practical tips
- Apply the serum to slightly damp skin after cleansing — hyaluronic acid binds the water that's on the skin rather than drawing it from deeper layers.
- Seal in the hydration with a moisturizer or oil — occlusion prevents evaporation.
- Use products that don't list ethyl alcohol as one of the first ingredients — it dries out the skin and can aggravate irritation.

FAQ
Yes. Hyaluronic acid (Sodium Hyaluronate, Hyaluronic Acid) in topically applied cosmetics is considered safe during pregnancy. It shows no systemic absorption at cosmetic concentrations and has no teratogenic effects.
Low molecular weight forms penetrate the skin more deeply, but studies have not shown systemic absorption following topical application. The SCCS has issued no warnings for any of the forms used in cosmetics.
Yes. When applied topically, hyaluronic acid does not pass into breast milk in clinically relevant amounts and is considered safe during lactation.
Cosmetic hyaluronic acid is a linear substance applied topically to the skin. Aesthetic medicine uses the cross-linked form, which is injected into the skin — this form must be strictly avoided during pregnancy.
