Tip: For enhanced absorption, apply to slightly damp skin or mist with Gaea's Gala toner first.
Full Ingredient List
We formulate with ingredients most brands can't touch. Because our formulas live their whole lives cold, shelf stability never enters the equation: no swapping fragile actives for tougher, weaker stand-ins, and no preservative system to design around. Just the best ingredient for the job, however delicate.

Key actives: lipid-soluble vitamin C (ascorbyl tetraisopalmitate), a form that crosses the skin's oil barrier; Siberian sea buckthorn, one of the most carotenoid-dense botanicals on earth; rosehip and plant squalane for vitamins A and E and barrier support.

Full list: Jojoba (Simmondsia Chinensis) Oil*, Rosehip (Rosa Canina) Oil*, Amaranthus Squalane Oil, Vitamin C (Ascorbyl Tetraisopalmitate), Cranberry (Vaccinium Macrocarpon) Seed Oil*, Sea Buckthorn (Hippophae Rhamnoides) Fruit Oil*, Strawberry (Fragaria Vesca) Fruit Extract, Vitamin E (non-GMO), Date (Phoenix Dactylifera) Seed Extract, Elderberry (Sambucus Nigra) Flower Extract, Carrot Seed (Daucus Carota) Oil*, Orange (Citrus Sinensis) Oil*, Caprylic/Capric Triglyceride, Pot Marigold (Calendula Officinalis) Flower Extract*, German Chamomile (Matricaria Recutita) Flower Extract*.

Storage
You don't need to refrigerate products during daily use, but we recommend finishing each bottle within 90 days of leaving the fridge. If you're not ready to start using a product right away, store it cold until you are (any household fridge is fine). Don't freeze water-based products, and shake well after thawing if any do freeze. Keep all products out of direct sunlight.
Common Questions
Do I need to refrigerate it?
No. We recommend finishing each bottle within 90 days of leaving the fridge and keeping it out of direct sunlight. A beauty fridge is a nice bonus, not a requirement: the cold-preservation advantage happens before the product ever reaches you.
When will I see results?
Brightness first: many reviewers describe a visible glow within the first two weeks, and the mini comfortably covers that window. Dark spots take longer, typically six weeks or more.
Will this break me out?
It's formulated with lightweight, non-comedogenic oils (jojoba, squalane, rosehip) that absorb without clogging pores. Many acne-prone customers report fewer breakouts after switching, not more.
Why is the serum crimson?
The color comes from sea buckthorn's carotenoids, among the most potent botanical antioxidants in skincare. The shade varies naturally from deep crimson to warm orange-red, bottle to bottle. Cold preservation keeps those carotenoids at full strength.
How long does the mini last?
About 3 to 4 weeks using 3-4 drops twice daily: the 8 ml bottle holds well over 150 drops. It's the same concentrated formula as the full size, in a bottle sized to let you experience the results before committing.

Three actives, full potency

The vitamin C serum that arrives alive

Cold-preserved from the moment it's formulated: no warm warehouses, no months on a shelf, no chemical stabilizers. Three actives reach your skin at the same potency as the day they were made. Tap a card to see the mechanism.

Lipid-Soluble Vitamin C

Reaches where pigment is made

Ascorbyl Tetraisopalmitate from a Japanese manufacturer. Unlike water-soluble L-ascorbic acid, it penetrates the skin's oil-based barrier to reach the deeper layers where pigment production, collagen synthesis, and oxidative damage are actually managed.

Siberian Sea Buckthorn Oil

Carotenoid-dense, omega-7 rich

One of the most carotenoid-dense botanicals on earth, exceptionally rich in omega-7. It accelerates the cell turnover that brings fresh, healthy skin to the surface and produces the visible glow reviewers describe within the first week. It's also the source of Cryo-C's signature crimson color.

The light-reflecting surface

Rosehip provides a natural source of vitamins A and E, supporting the skin's renewal cycle. Plant-derived squalane mirrors your skin's own sebum: lightweight and non-comedogenic, it strengthens the moisture barrier and creates the smooth, light-reflecting surface that makes radiance visible.

So what does all that heat do?

The Problem Was Never Your Routine.

Preservatives fight one problem. Heat causes three.

Bacterial growth 1

Bacterial Digestion

Bacteria multiply in warm formulas. Preservatives suppress them. Cold slows them too, without adding to what your skin has to absorb.

Oxidation reactions 2

Redox Reactions

Heat drives chemical reactions that degrade vitamin C, ceramides, and peptides. Preservatives don't slow this process. Cold does.

Enzymatic activity 3

Enzymatic Activity

Plant enzymes keep breaking down botanical compounds after harvest. Preservatives don't affect this. Cold puts them on pause.

Skincare mini fridge with a rotten banana
About those beauty fridges

Cold Can't Unspoil the Banana

Everyone wants fresh skincare. That's why beauty fridges are everywhere. But chilling a conventional serum makes about as much sense as refrigerating an old banana.

Your serum absorbed 1,956 degree-days of heat before it ever met a fridge. A banana at least has the courtesy to turn brown; a degraded cream looks and feels identical to a fresh one.

Beauty fridges make conventional skincare cold at the end. Wild Ice is cold from the beginning.

From our studio to your door

Cold from the very first step

Every Mini Cryo-C bottle is formulated in small weekly batches in our studio and held cold at 4°C, from raw ingredient through formulation.

Ingredients kept cold

Every ingredient stored at 4°C from the moment it arrives.

🧪

Formulated fresh

Formulated in small weekly batches, cold throughout.

📦

Held at 4°C

Finished bottles go straight into cold storage and stay there.

Shipped within days

Made fresh weekly, so actives are still active when they reach you.

So why don't all brands chill?

Between warm warehouses, hot freight, and un-chilled retail shelves, it's nearly impossible to get big while staying cold. The industry won't change until enough customers demand it. Someone had to take the plunge first, so we did.

Mila, founder of Wild Ice Botanicals

Fresh was never optional

I grew up in the Soviet Union watching my grandmother make skincare from her garden. It worked because it was fresh. There was no other option.

In 2018, I began cold-storing every ingredient and finished product. I hadn't changed a single formula; the reviews changed on their own. A national retailer offered us shelf placement but refused to refrigerate. We walked away.

Every product is made in our studio, in small weekly batches. I've worn every formula through three pregnancies. Every bottle is one I'd use on my own family.

Common questions about cold-preserved skincare

Frequently Asked Questions

Cryo-C is formulated with lightweight, non-comedogenic oils (jojoba, squalane, rosehip) that absorb quickly without clogging pores. Many customers with acne-prone skin report fewer breakouts after switching to Cryo-C, not more. When skincare ingredients degrade through heat and oxidation, they form new compounds that can be comedogenic or sensitizing. Cold preservation prevents that degradation, so the formula that reaches your skin is the one that was designed.
Yes. The oils in Cryo-C (jojoba, squalane) are structurally similar to your skin's own sebum. They help regulate oil production rather than adding to it. The serum absorbs quickly and doesn't leave a heavy or greasy feel.
You don't need to refrigerate products during daily use, but we recommend finishing each bottle within 90 days of leaving the fridge. If you're not ready to start using a product right away, store it cold until you are (the kitchen fridge is fine). Don't freeze water-based products, and keep all products out of direct sunlight. A beauty fridge is a nice bonus, not a requirement: the cold-preservation advantage happens before the product ever reaches you.
Most reviewers describe a brighter, more glowing look within the first two weeks. Deeper changes take longer: dark spots and uneven tone typically improve over six weeks or more, and the customer photos above show real timelines from six weeks to four months. Consistency matters more than quantity; twice daily, every day.
About 3 to 4 weeks using 3-4 drops twice daily: the 8 ml bottle holds well over 150 drops. The full-size bottle lasts 6 to 8 weeks.
Yes. Identical formula, same weekly batch cycle, same cold storage. The only differences are the bottle size and the dropper: the mini exists so you can experience the results before committing to the full size.
The full-size bottle uses a pump because it lives on your vanity for 6 to 8 weeks, and a pump keeps fingers and air out of the formula that whole time. The mini is finished in about half that window, so a dropper keeps the bottle compact and travel-friendly. The same guidance applies to both: finish within 90 days of leaving the fridge.
If you have a scar less than two years old, Cryo-C can help diminish its appearance. We've had customers report significant improvement. The sooner you begin using it after the wound has fully healed, the better the results tend to be.
The color comes from sea buckthorn's carotenoids, some of the most potent botanical antioxidants in skincare. The exact shade varies naturally from bottle to bottle, deep crimson through warm orange-red, because real botanicals vary from harvest to harvest. Cold preservation keeps those carotenoids, and the color they bring, at full strength.
No synthetic dyes (the deep crimson color comes from sea buckthorn oil), no synthetic fragrances (the scent comes from rosehip, orange, and carrot seed oils), no chemical preservatives, no parabens, no phthalates, and no animal-derived ingredients. Cryo-C is 100% vegan and cruelty-free.
