Breastfeeding safe skincare: what changes after birth

The list of skincare ingredients to avoid gets shorter after birth, not longer.

Pregnancy and breastfeeding are treated as one long restriction almost everywhere you look. They are two different questions with two different answers.

Here is what changes, alongside postpartum skin care for what your skin is doing at the same time.

Is skincare safe to use while breastfeeding?

Most skincare is appropriate to use while breastfeeding, and the restrictions are narrower than they were in pregnancy.

A 2026 review in the International Journal of Dermatology makes this point directly, that pregnancy and breastfeeding should not be approached as equivalent, because the way a molecule travels differs between them.¹

In pregnancy, anything that reaches your bloodstream shares a blood supply with your baby. After birth, that shared supply is gone.

What replaces it is a longer and much leakier route. A molecule has to get through your skin, into your blood, out of your blood into milk, then survive your baby’s digestion.

Each of those steps removes a large share of what started on your face.

That is why the review concludes that during breastfeeding most topical treatments can be considered where the amount reaching your bloodstream is expected to be minimal and the treated area avoids direct contact with your baby.¹

How does skincare get into breast milk?

A molecule has to clear three separate hurdles to reach your baby through milk, and most skincare ingredients fail at the first one.

The first is your skin. Most products are built to stay in the upper layers of your skin and we cover this in the article does skincare get into your bloodstream.

The second is the milk-producing tissue in your breast, where transfer happens mostly by passive diffusion across a single layer of cells. How much crosses depends on the size of the molecule, how fat-soluble it is, how tightly it sticks to proteins in your blood and whether it carries an electrical charge.²

Once feeding is established, the gaps between those cells close, so a molecule has to pass through them rather than slipping between.²

The third is your baby’s gut. Anything that does reach milk still has to be absorbed from the digestive tract.

Researchers describe the result as the relative infant dose, meaning the share of your own dose your baby receives. A long-standing World Health Organisation threshold treats anything under 10% as generally acceptable.³

Which skincare ingredients become acceptable again after birth?

Topical retinoids are the clearest example, moving from the avoid list in pregnancy to lower risk while breastfeeding.

The reason is the three hurdles above. Topical retinoids are poorly absorbed through skin, and only trace amounts reach breast milk.⁴ The National Library of Medicine’s lactation database rates them low risk.⁴

What can gently start to be reintroduced with caution:

• Topical retinoids. Rated low risk by the National Library of Medicine’s lactation database.⁴
• Hydroquinone. Not contraindicated while feeding, though some experts would rather you didn’t use it long term.⁵
• Salicylic acid and glycolic acid. Both listed as acceptable.⁴
• Azelaic acid. Low risk, and only 4% to 8% of it gets through your skin at all.⁴

Niacinamide during pregnancy, vitamin C and hyaluronic acid were never in question at either stage. They weren’t on the pregnancy avoid list and they’re not on this one.

Which ingredients need more care while breastfeeding, not less?

Anything applied to your breast or chest needs more thought than it did in pregnancy, because your baby’s skin and mouth now make direct contact with it.

The advice on topical retinoids is to keep them off the breasts and anywhere else that touches your baby’s skin.⁴

The lactation database says the same for hydroquinone and for azelaic acid, that the product should not reach your baby’s skin and should not be swallowed by the baby when coming in to contact with the mother's skin.⁵˒⁶

Topical clindamycin, a prescription acne treatment, is considered appropriate during pregnancy. While breastfeeding, the advice is to avoid the chest area because of a possible increase in loose stools in breastfed babies.⁴

Texture matters here too. For anything applied to the breast, water-based creams and gels are preferred over ointments, which can expose a baby to larger amounts of the mineral oils they are built on.⁶

Do you need to wash skincare off before feeding?

Not for a face routine and yes for anything you have applied to the breast or nipple.

A moisturiser or serum on your face does not come into contact with your baby’s mouth during a feed, so there is nothing to remove.

Products applied to the breast are different. The consistent advice across lactation sources is to stop your baby’s skin from touching treated areas and to stop the product being swallowed from your baby coming in to contact with your skin.⁵˒⁶

So keep your actives on your face and neck.

Choose a plain moisturiser if something needs to go on your chest and rinse anything medicated from the breast or nipple area before a feed.

When should you change your skincare routine after birth?

There is no fixed date and the decision rests on whether you are still feeding and how your skin feels rather than on how many weeks have passed.

Two things move at different speeds after birth. Your hormones drop within days AND your skin takes considerably longer to settle.

A sensible order is barrier and hydration first, then pigmentation, then everything else.

For most women, the first thing worth changing is not about the active ingredients at all. It's whether your cleanser and moisturiser still suit how your skin feels now.

If you're still feeding, the ingredient questions above apply. If you've stopped, the pregnancy list no longer applies and you are back to ordinary skincare decisions.

What this means for your routine

Nothing in the nātelle range needs to change when you start breastfeeding, because every formula was already built purposefully for your motherhood journey.

If your skin feels tight and reactive, start with the Barrier Comfort Moisturiser, our moisturiser during pregnancy.

We built it on glycerin, squalane and three ceramides, EOP, NP and AP, rather than a single heavy occlusive, so it supports the barrier instead of only sealing it.

It sits in the Postpartum Kit.
