Description
Made for a body that’s changing.
Arc is our pregnancy and postpartum body care collection — deep, comforting care for skin that’s stretching, tightening or feeling dry.
Your skin is doing something remarkable. This is made to keep it comfortable while it does.
Suitable For
- Who it's for: Pregnancy and postpartum.
- Where to use: Belly, hips, thighs and anywhere skin feels dry or tight.
- Best for: Daily moisturising, massage and supporting skin as it stretches.
Caring for a baby too? Halo is our everyday care collection for delicate baby skin and the whole family.
Pregnancy asks extraordinary things of the body.
Arc was created to care for skin through it — a small number of thoughtfully chosen botanical ingredients that nourish, soften and comfort stretching skin. Rather than adding more ingredients, we focused on choosing the right ones: simple, fragrance-free formulas for pregnancy and the months after.
Built around the ingredients doing the work.
Sweet almond, jojoba and squalane are the foundation of the formula. No water, no fillers.
The Ritual
- Cleanse. Warm water, gentle hands. Pat dry.
- Apply the Oil. A few drops, worked into skin with slow, upward strokes.
- Seal with the Balm. A thin layer, warmed between fingertips first.
Every ingredient in Arc is chosen for its traditional use in supporting skin through pregnancy and postpartum.
What to Expect
With consistent use, skin feels soft, supple and comfortably moisturised. Dry areas feel deeply nourished, tightness feels less noticeable, and skin feels supported through every stage of pregnancy and postpartum.
Lightweight nourishment for stretching skin.
A silky botanical oil created for everyday massage throughout pregnancy and postpartum.
Designed to give hands enough glide for massage while absorbing comfortably into the skin afterwards.
- Feel: Silky. Lightweight. Fast-absorbing.
- Finish: Leaves skin feeling soft, supple and never greasy.
How to use
Massage gently into the belly, hips, thighs and anywhere skin feels tight or dry. Use daily throughout pregnancy and for as long as your skin benefits from the extra nourishment.
Rich moisture. Lasting comfort.
A concentrated botanical balm for areas that need deeper nourishment as skin stretches.
- Feel: Rich. Buttery. Melting.
- Finish: Melts into the skin with a smooth finish that feels nourishing without feeling heavy.
How to use
Warm a small amount between your fingertips before massaging into the belly, hips, thighs or anywhere skin feels particularly dry or tight. Use daily throughout pregnancy and postpartum.
Why Shea Butter?
We lead the balm with shea butter because of its naturally rich fatty acid profile, balancing it with lighter botanical oils to create lasting nourishment without heaviness.
Why Tallow?
Alongside shea, we use responsibly sourced, grass-fed tallow for its naturally skin-compatible lipid profile, adding to the balm's rich, lasting comfort without feeling heavy.
A complete ritual for every stage.
Begin with Arc Belly Oil for lightweight daily nourishment and massage, then layer Arc Belly Balm over areas needing deeper moisture — a simple ritual that grows with you, from the first signs of stretching through the months after birth.

How are the Oil and the Balm different?
Arc Belly Oil is lightweight and fast-absorbing, making it ideal for daily massage. Arc Belly Balm is richer, providing longer-lasting moisture where skin feels particularly dry or tight. Use them individually or layer them together.
Can I use them together?
Yes. Massage Arc Belly Oil into clean skin first, then apply Arc Belly Balm wherever skin needs extra nourishment.
Can I use Arc every day?
Yes. Both the oil and balm are designed for everyday use throughout pregnancy and postpartum.
When can I start using Arc?
Arc is created for changing skin throughout pregnancy and after birth. As with any new skincare product, we recommend patch testing first and speaking with your healthcare professional before introducing new products during pregnancy or while breastfeeding.
Can I continue using Arc after pregnancy?
Absolutely. Arc was designed to support skin through pregnancy and postpartum, and many people continue using it wherever skin feels dry, tight or in need of lasting nourishment.
Does Arc contain nuts?
Yes. Arc contains Sweet Almond Oil, which is derived from a tree nut. If you have a nut allergy, we recommend avoiding Arc or speaking with your healthcare professional before use.
How is Arc different from your other collections?
Arc is created specifically for the changing skin of pregnancy and postpartum. Halo is everyday care for healthy skin at every age. Ember is designed for skin that is dry, sensitive or easily irritated.
Why is Arc fragrance-free?
Fragrance and essential oils are among the most common causes of skin irritation. We leave them out so Arc can focus on simple, thoughtful care when skin is more reactive than usual.
Use within 9 months after opening.
Store below 30°C. Protect from direct sunlight.
Keep the lid tightly closed after each use.
For external use only.
Avoid contact with eyes.
If irritation occurs, discontinue use.
As we use natural ingredients, slight variation in colour and texture between batches is normal.
