Tallow and Baby Skin: What We Won't Tell You to Do

If you've spent any time in tallow-skincare circles, you've likely seen it recommended for babies — cradle cap, nappy rash, general dryness. It has a genuine traditional history there. We still want to be careful and honest about this one, more than any other topic we write about.

The reasoning behind the traditional use makes sense on paper: tallow is a single, minimally processed ingredient with no synthetic fragrance, preservatives, or the long ingredient lists that can make it hard to identify what's actually triggering a reaction on a baby's skin. Fewer ingredients can mean fewer things to react to.

But "natural" and "simple" are not the same thing as "proven safe for infant skin." Babies' skin is thinner, more permeable, and still developing its barrier function compared to adult skin — which cuts both ways. It can mean a gentle, minimal-ingredient product is genuinely a sensible choice, but it can also mean a baby's skin absorbs and reacts to things more readily than yours would, including ingredients that are perfectly fine for adults.

Because of that, we're not going to tell you tallow is safe for your baby, and we're not going to tell you it isn't — that's not a call we're qualified to make for your child, and it isn't a decision that should be based on a skincare brand's blog post. None of our current products are formulated, tested, or labelled for infant use. If you're considering it, the right first step is a conversation with your baby's paediatrician or a dermatologist, particularly for newborns, broken or irritated skin (like nappy rash), or if there's any family history of skin allergies. If you do get the go-ahead to try something, a tiny patch test on a small area first, well away from broken skin, is the standard precaution — and that advice should come from a professional, not from us.
