For many years, before Sēlkyn Tallow existed, I sat with families in the hours after birth. As a home-birth midwife, I watched hundreds of newborns arrive into the world with skin that had never touched anything but amniotic fluid and vernix. I watched hundreds of parents reach, almost on instinct, for something to put on that skin. The question underneath all of it was always the same: is this actually safe for my baby?
It's the question that led to Sēlkyn Tallow in the first place. When my own daughter became pregnant and chose a home birth and a non-toxic life for her baby, I wanted to make her something safe enough for a newborn's skin from day one, and rich enough to support hers through postpartum recovery. I wanted something for both; the same jar, no compromise, no double standard between what's "safe for baby" and what mum settles for herself. That's still the standard every Sēlkyn product is made to.
Why newborn skin needs something different
A newborn's skin barrier is still maturing. It's thinner, loses moisture more easily, and is more permeable than adult skin, which means whatever goes onto it is more readily absorbed. This isn't a reason to avoid moisturising newborn skin, as dryness and peeling in the first weeks is completely normal and often benefits from gentle support. However It's a reason to be genuinely careful about what that support is made of. Synthetic fragrance, preservatives and the long ingredient lists common in conventional baby products are exactly what a still-maturing skin barrier doesn't need to process.
Tallow's advantage here is structural, not marketing. Its fatty acid profile is close to the lipids human skin already produces, which is why it tends to be recognised and absorbed rather than sitting on the surface. Combined with the fact that our balms contain nothing but organic tallow and whole botanicals, slow-infused rather than added as isolated essential oils, there's very little in the jar that a newborn's skin has to work to process.
What I'd want every new parent to know
None of this replaces the advice of your own midwife, GP, maternal health nurse or paediatrician, especially if your baby has a diagnosed skin condition, a rash that concerns you, or was born early. Always check with them first. What I can offer is what two decades of attending births taught me about ordinary, healthy newborn skin:
- Less is more in the first weeks. Newborn skin is shedding its outer layer naturally in the first week or two (this is normal, not dryness that needs fixing). A small amount of a simple, whole-ingredient balm on visibly dry areas is usually all that's needed.
- Patch test first, as you would with any new product. Apply a small amount to a small area of skin and wait 24 hours before wider use, particularly if there's any family history of skin sensitivity.
- Simpler is safer. The fewer ingredients, the fewer things there are for a new skin barrier to react to. This is the whole reason our balms stay to a short, whole-ingredient list rather than a long one.
- Delicate areas need extra care. A little goes further than you'd think. Tallow absorbs deeply rather than sitting on top, so a thin layer is usually enough.
The postpartum side of the same jar
The newborn in the room is never the only person whose skin needs support. Postpartum skin is doing its own quiet work, stretched, healing, often depleted from pregnancy and the early weeks of feeding and broken sleep. This is the other half of why Sēlkyn Tallow started as one jar for both of you: the same organic, slow-infused tallow that suits a newborn's sensitive skin is rich enough to support a healing postpartum body, without needing a separate "gentle" version and a separate "grown-up" version competing for space on the same shelf.
Stretch marks, in particular, are something I sat with countless women through, both before and after birth. They're not a flaw to erase, they're a normal part of skin adapting to a body that grew a person, but keeping the skin well-nourished through pregnancy and postpartum can support its elasticity and comfort as it changes. A regular, gentle massage with a rich, simple balm is a practice as old as pregnancy itself, and it's one of the most common things new and expecting mothers ask me about.
Why this is different from what most brands will tell you
A lot of "safe for baby" marketing is exactly that, marketing, applied to a formula that isn't meaningfully different from the adult version sold in the same range. Sēlkyn Tallow was built the other way around: designed first for the most sensitive skin we make anything for, a newborn's, and then trusted as rich enough for every other stage of life from there. That's not a claim I make lightly. It's the actual reason the brand exists.
