What preservative-free means on our labels
Whether a formula needs a preservative comes down to water. Microbes need it to multiply, so an oil, a butter or a sugar scrub gives them almost nothing to grow in and can go without a broad-spectrum preservative system. That is the sense in which every product on this page is preservative-free: Cryo-C and Berry Boreal Bod are built on botanical oils, Rarify on a botanical oil blend, Wintry Fix on sugar, oils and butters, and Laurel is a cured bar of saponified olive and laurel oils. Their labels name no preservative because there is no water phase to guard.
Preservative-free describes part of our line, and we would rather say so here than let you find out from a label. Four of our water-based formulas, the B-Meltee cleanser, D.B.T. Baba Yaga cream, Yuki-Onna mask and Eyecicle eye serum, name a short trio near the end of their lists: benzyl alcohol, salicylic acid and sorbic acid. Water needs guarding once a jar is open, and we chose a short system with published safety reviews rather than none; the article on how preservative-free skincare is kept safe walks through each one with its sources. Two more, Gaea's Gala and 7 Winters, are built on ferments and glycerin rather than one of those preservatives. We make no self-preserving claim for either, and we advise refrigerating them after opening for best freshness. None of the six appear on this page.
Cold does a different job. Every ingredient and every finished bottle here is kept refrigerated at about 4 C in our studio from formulation until the day it ships, because cool temperatures slow the chemistry that ages fragile actives like the vitamin C ester in Cryo-C and the blue tansy in Berry Boreal Bod. That argument is about potency rather than safety, and the evidence sits in our science hub, Why Your Skincare Loses Potency, and What Actually Protects It. Once a bottle is home, a cool, dark cabinet is all these oils ask for; the fridge is optional and can cloud jojoba harmlessly.
