Yuki-Onna: Triple-Acid Exfoliating Mask

It helps but it's not required. Our products are formulated to remain stable at room temperature for the duration of normal use (most customers finish a product within 6-8 weeks). The cold preservation advantage happens before the product reaches you: cold-stored ingredients, cold formulation, cold warehousing. That's where conventional skincare accumulates months of heat damage that we avoid entirely.

If you do have a beauty fridge, storing Wild Ice products in it will extend their potency even further. But you're already getting the product at a level of freshness that room-temperature brands can't match, fridge or no fridge.

A few hours of doorstep time doesn't meaningfully affect the product. Conventional skincare accumulates thousands of degree-days of heat damage across its supply chain lifecycle. A package sitting in afternoon sun for four hours might add a single-digit number of degree-days. The gap between Wild Ice and conventional products is so large that even a full day on a hot porch leaves our products with a fraction of the heat damage a conventional product accumulated before it was even sealed in its box.

Most customers use a product within 6-8 weeks of receiving it. During that time, stored at room temperature, the product remains stable and effective. If you're not planning to start using it right away (gifting it, finishing another product first), store it in any refrigerator until you're ready. The kitchen fridge works fine.

Our products don't contain the heavy chemical preservative loads that give conventional skincare an 18-month shelf life, because they don't need them. They're made fresh, shipped fast, and designed to be used, not stockpiled.

Mila formulated and tested every Wild Ice product during pregnancy and breastfeeding. She has worn every formula through three pregnancies. Our products use no parabens, no synthetic fragrances, no phthalates, and no chemical preservatives: the ingredients you're typically told to avoid during pregnancy aren't in the bottle to begin with.

Hundreds of customers have used Wild Ice products during pregnancy and breastfeeding. That said, we always recommend checking with your OB or midwife before adding anything new to your routine. Every practitioner has their own guidance, and we respect that.

Because it's expensive, logistically difficult, and incompatible with how the industry distributes products. Conventional skincare is built to survive months of warm warehousing, long-haul freight, and retail shelf display. That entire infrastructure depends on products being shelf-stable in heat.

Major retailers won't install product fridges that rearrange floor space and make their other lines look inferior. Amazon requires products to withstand 155°F indefinitely, with no exceptions. We asked.

Cold preservation requires a completely different model: small batches, dedicated cold storage, direct-to-consumer shipping, and no retail partners. Most brands can't or won't restructure their entire operation around temperature control. We built Wild Ice from scratch specifically to do this, and we turned down retail distribution to protect it.

Not yet, though we're actively working on it. Here's why it matters less than you'd think.

The days a product spends in a shipping box are a tiny fraction of its total lifecycle. The real damage in conventional skincare happens during months of warm ingredient storage, warehousing, and retail display. That's where thousands of degree-days of heat damage accumulate. Transit adds a small, single-digit number by comparison.

We could put a cold pack in every box. But that would be an expensive gesture solving roughly 2% of the problem while raising your price. The cold preservation that matters is everything before the box, and that's the part we've solved.
