There is a particular kind of trust involved in putting something on a baby's skin.
It is not the same as choosing a product for yourself. When you choose for yourself, you carry context — you know your skin's history, you know what it tolerates, you can read a reaction and adjust. When you choose for a baby, you're working with skin that is still developing its barrier function, that communicates discomfort only through distress, and that deserves formulas built with a different level of consideration.
The Halo collection was built around this. Not around what sells in the baby category — which tends toward lavender, chamomile, and the word 'gentle' applied to formulas that contain more than their labels suggest. Around what baby skin actually needs.
Baby skin has a lower pH than adult skin and a thinner stratum corneum, the outermost layer of the skin barrier. This means it is more susceptible to transepidermal water loss — the passive evaporation of moisture through the skin — and more reactive to potential irritants. Fragrance is an irritant. Essential oils are irritants. We use neither.
What we use instead are oils chosen for their barrier-supporting properties, their low comedogenic potential, and their compatibility with sensitive skin. Meadowfoam seed oil appears in both the Halo Oil and Halo Balm because its fatty acid profile is among the most stable and skin-compatible available. Squalane because it mirrors the skin's own lipids. Tocopherol because it supports skin integrity without adding sensitisation risk.
Nothing in the Halo collection exists to smell appealing in the bottle. Everything in it exists to serve your baby's skin.
That is the oath.
