— The one ingredient

Faroese brown kelp, fermented.

Laminaria hyperborea · cold-pressed, oak-barrel-aged 14 months

Mire's entire product line is built around a single ingredient: a species of cold-water brown kelp called Laminaria hyperborea, which grows in tight forests off the northern coast of the Faroe Islands. Our four divers harvest it by hand, in a six-week window each autumn, from a single seven-hectare bay we lease from the Faroese fisheries authority.

What makes the kelp interesting isn't the kelp itself — it's what happens after. The harvested fronds are cold-pressed within six hours, the liquid moved into hundred-litre oak barrels lined with Faroese sea salt, and left to ferment for fourteen months in a converted boathouse on the southern coast of Streymoy. The fermentation produces a slow, low-pH wash that is unusually rich in fucoidan, mannitol, and a class of polyphenols that the cosmetics industry has spent the last decade trying to synthesise without success.

Every one of our five products is, at its base, this fermented kelp wash. No filler oils. No fragrance. No alcohol. The differences between formulations are differences in concentration, viscosity, and what we pair it with. Always the same kelp, the same bay, the same fourteen months.

— How a bottle is made

Eighteen months from frond to bottle. no faster.

The slow part of skincare is not the formulating, it's the waiting. We start with kelp that won't be a bottle for a year and a half, and we don't release a batch until it's ready.

01

Harvest by hand

— October · six weeks · 4 divers

Our divers harvest from the same seven-hectare bay off Streymoy, every autumn. Each frond is cut by hand, never dredged. Yield is roughly eleven tonnes per season — enough for 142 bottles per finished batch.

02

Cold press

— Within 6 hours · 4°C

Within hours of being cut, the fronds are washed in seawater and cold-pressed under granite stones in our boathouse on Streymoy. The press juice is racked into oak barrels lined with Faroese sea salt the same evening.

03

Ferment & rest

— 14 months · oak barrels

The wash ferments for fourteen months in 100-litre Faroese oak barrels — long enough for the fucoidan to concentrate, the polyphenols to bloom, and the smell to mellow from kelpy to something closer to grass.

04

Bottle & ship

— 142 bottles / batch

Each batch yields about 142 bottles. We bottle by hand, label by hand, and ship from Tórshavn by air-freight every six weeks. There's no warehouse — each bottle is in stock for an average of nine days.

— The full range · five products

Five things we make. that's it.

Mire has five products and no plans to introduce a sixth. Every one is built on the same fermented marine base — the differences are concentration, paired ingredients, and how you use them.

— The ritual

A simple order, twice a day. that's all.

If you use everything we make, the routine takes about four minutes in the morning and six at night. If you use only the serum, it takes ninety seconds. We've designed the line so you can stop at any step and the skin doesn't punish you for it.

Cleanse (evening only)Two pumps of the sea-rose balm, warmed between palms, massaged dry, removed with a damp muslin cloth.
— 2 min
ii.
MistThree or four pumps of the salt-cliff mist, on damp skin — the serum sinks better into a wet face.
