Description

The moment just before the cold hits. Sharp, mineral, completely awake.

Early morning in Torekov. A robe down the wooden steps, bare feet on wet planks, and the second before you jump into water still cold from the night. Cold Plunge is built around that moment: bright citrus, a cool rush of sea salt and a clean mineral finish that stays close to the skin.

 

Top: Grapefruit, Bergamot, Rosemary
Heart: Sea Salt Accord
Base: Mineral Musk

 

Why it matters
Most fragrances don't tell you what's in them. The word "parfum" on a label can cover dozens of undisclosed ingredients, some linked to hormone disruption. Your hormones shape more than you think, at every stage of life, and what you put on your skin every day shouldn't interfere with them. Every ingredient in Cold Plunge is named on the label, and the formula is Tested for Hormone Safety.

 

Developed in Paris, bottled in Sweden.
Unisex perfume oil · Roll-on

How to wear

Roll onto pulse points: wrists, neck, behind the ears. Oil sits closer to the skin than an alcohol spray, so reapply once more after a while if you want more presence.

What hides in the word “parfum”?

Fragrance law doesn't require a brand to disclose what's inside, most hide behind the word “Parfum.” We list every ingredient on the label anyway.

On an ingredient list, “parfum” isn't one ingredient. It's a catch-all. Behind it there may be ten substances or three thousand, and because the formula counts as a trade secret, the person who reads the label learns about as much as the one who doesn't.

A typical label

Alcohol denat., Parfum, Aqua.

One word. Anywhere from a few to thousands of substances.

Questions you might have.

What are Under Your Skin Fragrance Oils?
A roll-on perfume oil (huile parfumée) with every ingredient on the label. Four scents, inspired by the Swedish countryside. Made in Paris. No ethanol, so it wears softer and closer to the skin than a spray.
What are the four scents?
Swedish Candy (fruity, earthy)
A rhubarb stalk pulled from the garden, dipped in a small dish of sugar, and eaten on the spot.
Top: Wild Rhubarb
Heart: Scandinavian Red Currant
Base: Cedar, Moss

She Wore Rose (floral, musky)
A crown of wild roses, picked that morning, worn until the sun finally sets, sometime after midnight.
Top: Bergamot, Pear
Heart: Turkish Rose
Base: Sandalwood, Musk

Garden Skin (green, citrus)
The smell left on your hands after an afternoon spent picking tomatoes off the vine.
Top: Lemon, Lime, Petitgrain
Heart: Tomato Leaf, Freesia
Base: Cedar, Sandalwood, Musk

Cold Plunge (fresh, mineral)
The moment just before the cold hits. Sharp, mineral, completely awake.
Top: Grapefruit, Bergamot, Rosemary
Heart: Sea Salt Accord
Base: Mineral Musk
Which one should I choose?
Start with what you already love wearing.

Swedish Candy (fruity, earthy): the summer ritual of pulling rhubarb from the garden and dipping it in sugar. Sweet and tart at first, then it settles into cedar and moss, like the soil it came from. For you if you love fruity scents with a little edge.

She Wore Rose (floral, musky): Midsummer. A crown of wild roses, worn from morning until long after the sun goes down. Bergamot and pear on top, rose at the heart, and musk that stays on the skin when the night ends. For you if you love florals, even if you're not usually a rose person. The pear and musk keep it from feeling old-fashioned.

Garden Skin (green, citrus): late summer, picking tomatoes off the vine. Green and bright, citrus and tomato leaf, with warm wood underneath. For you if you love green, fresh-cut scents.

Cold Plunge (fresh, mineral): the Swedish cold swim, the moment before you go in. Grapefruit and rosemary, salt air, mineral musk. For you if you love clean, fresh scents that feel like a deep breath.

How are they different from other perfumes?
- Every ingredient listed. Most brands write "fragrance" or "parfum" and stop there. We list everything that's inside.
- Reviewed by toxicologists in Sweden. Independent toxicologists assessed the formula for hormone safety, the same standard we use for our hair and scalp care.
- Alcohol-free. No ethanol, so it won't dry out your skin the way alcohol can, and the scent doesn't flash off in the first few minutes.
- No phthalates. Many brands use them to make a scent last longer. We don't.
- Made in Paris. Inspired by Sweden, crafted with some of the finest perfume ingredients in the world.
What do the perfume oils contain?
Each scent is about 20% fragrance and 80% Triethyl Citrate, a carrier made from citric acid. The full ingredient list for each scent is on the box and on the product page.
What is Triethyl Citrate?
A clear ingredient made from citric acid, used in place of perfumer's alcohol. It carries the scent without drying out your skin the way alcohol can. It's also used in food and pharmaceuticals.
Why are they called perfume oils?
"Perfume oil" is the name for alcohol-free perfume, as opposed to a spray. The scent itself is a fragrance oil, and here it's carried in Triethyl Citrate instead of alcohol. It feels lighter than other carrier oils, but it still wears close to the skin.
Why don't you just say "fragrance" or "parfum" like other brands?
Because one word can hide dozens of ingredients. We'd rather you see everything and decide for yourself.
Is it natural or organic?
No, and that's on purpose. We choose ingredients for how well they're tested for safety, not for whether they come from nature or a lab. Some of the best-studied, safest fragrance materials are synthetic, and "natural" doesn't automatically mean gentler on your skin or hormones. That's why we list every ingredient on the label: so you can see exactly what's inside and decide for yourself. Our perfume oils don't carry a natural or organic certification.
Are there allergens?
Yes. Every fragrance contains some allergens, natural ones included. EU law requires certain fragrance allergens to be named on the label when they're present above a set level, and we list them all. You can find the full ingredient list for each scent on the box and on its product page.

If you have a known allergy or sensitive skin, check the ingredient list before you buy. When trying a new scent, apply a little to your inner wrist first and wait 24 hours.
How do I apply it?
Roll onto your pulse points: inner wrists, the side of your neck and behind your ears. One or two swipes on each is enough. Let it settle into your skin, and don't rub your wrists together, because that breaks down the top notes faster.
How long does the perfume oil last?
It depends on your skin type, the climate and how much you apply, so we don't give a set number of hours. Perfume oils wear differently from sprays. With no alcohol to evaporate, the scent stays close to your skin and unfolds gradually, instead of projecting strongly at first and then fading. Most people find it a softer, more personal scent that stays with them. For more presence, apply a little more or reapply through the day.
Why can't I smell it after an hour?
It's probably still there. Your nose gets used to a scent you've been wearing for a while and stops noticing it. Ask a friend, or smell your wrist after a break.
Will it stain my clothes?
Let it dry on your skin before getting dressed. As with any perfume, avoid applying it directly onto silk or light-coloured fabrics.
Can I put it in my hair?
It's made for skin, but if you'd like to scent your hair, roll a little onto the ends or onto your brush rather than your scalp.
How should I store it?
Keep the cap on and store it away from direct sun and heat. A drawer or cupboard is ideal. Best used within 24 months of opening.

Where it comes from

Essential Oil
Pressed or distilled directly from a plant: peel, wood, root, leaf, seed or resin.
Natural Extract
A concentrated plant extract or absolute, such as rose or pink pepper.
Plant Derived
Made from a plant material in one or two steps, such as cedarwood or clary sage.
Nature-Identical
The same molecule a plant or fruit makes, produced for purity and consistency.
Safe Synthetic
Made in a perfumer’s lab rather than harvested from a plant. Some scents would take fields of flowers or slow-growing trees to extract, so we make them in a lab instead and leave the land alone. Others, like sea salt, can’t be taken from a plant at all.
