Vital Theory
Cordyceps Radiance Serum · 30 ml / 1 fl oz
Vital Theory is a lightweight radiance serum. Cordyceps mushroom and niacinamide help even the look of tone and refine the appearance of texture, while Tremella delivers deep, weightless hydration — for skin that looks brighter, fresher, and more radiant.
Who it's for
Anyone who wants brighter, more even-looking skin in a lightweight serum that layers under everything. Gentle enough for most skin types; patch test first if your skin is reactive.

How to use it
Apply 1–2 pumps to clean skin, morning and evening. Let it absorb, then moisturize, and use sunscreen in the morning.
Niacinamide layers well with vitamin C, retinol and Copper Theory. Using both serums? Try Vital in the morning and Copper at night.
When to judge it
Skin feels hydrated from the first use. For brighter, more even-looking tone and texture, use it daily for 4–8 weeks before you decide.

The ritual
Start with clean, slightly damp skin, morning and evening.
Press gently into the face and neck. A little goes a long way.
Let it absorb fully before your moisturizer. Use daily for best results.
The science behind every bottle
Each active earns its place. We read the research as supportive of mechanism — not as proof of any outcome.
A functional mushroom rich in natural compounds and prized in traditional practice. In Vital Theory it's the glow active, and the reason the serum is amber. Chosen for skin that looks brighter and more awake. Some of it is grown on our own farm in Missouri.
Vitamin B3, a well-tolerated all-rounder that helps even the look of tone, refine the look of texture and support a comfortable moisture barrier. It layers easily with almost any routine.
The snow mushroom's polysaccharides hold up to 500× their weight in water for deep, weightless hydration — keeping radiance from tipping into tightness.
Chosen with intention, down to the pump
Every bottle is an airless pump, which keeps air out of the formula and dispenses a measured amount. We make small batches every week and batch-code each one, so every bottle is traceable. The amber color comes from the cordyceps itself.
Questions, answered
Can I use it with vitamin C or retinol? +
Yes — niacinamide is well tolerated alongside most actives. Introduce one new product at a time and patch test if sensitive.
How soon will I see a difference? +
Skin feels hydrated from the first use. Brighter, more even-looking tone builds with daily use, so give it 4–8 weeks.
Is it fragrance-free? +
Yes. No added fragrance and no colorants; the amber comes from the cordyceps. The full ingredient list is on this page.
Pregnant or breastfeeding? +
