WHY SEVERN EXISTS
Skin changes. So must your skincare.
Skin collagen declines by roughly 1% with each adult year.1 The barrier’s own lipids decline with age2 and repair runs measurably slower3 — and when estrogen shifts, the change accelerates: studies in postmenopausal women measured as much as 30% of skin collagen lost in the first five years.4 We formulated for the change — deliberately, at the levels the research used, with every choice on this page open to inspection.
WHAT EACH FORMULA COVERS
Each product stands alone.
Together, they cover more.
ATHENA and ARTEMIS are each formulated to work on their own. Used together, they are built to complement each other — covering most of what changing skin asks for.

TWO FORMULAS. EACH COMPLETE.
Intentional formulation,
not trends.
Every active has a native environment — a medium it dissolves in, stays stable in, and performs best in. So we divided our actives the way chemistry divides them: by function. The water-compatible actives — peptides, bifida ferment, niacinamide, ectoin, hyaluronic acid — live in ATHENA, a fast-absorbing serum that meets bare skin first. The oil-compatible actives — barrier lipids, cholesterol, phospholipids, and vitamin C in its oil-soluble form — live in ARTEMIS, a cream that is their natural home. One formulation philosophy, two products: each active placed exactly where it works best.
Built to compound.
ATHENA is complete on its own. ARTEMIS is complete on its own. Together, they cover most of what changing skin asks for — water-compatible actives in the serum, lipids and oil-soluble actives in the cream, each where its chemistry works best.
Split by design, not by marketing.
OIL-COMPATIBLE ACTIVES
ARTEMIS Omni-Restorative Cream
Restorative cream. The natural home for lipids and oil-soluble actives.
DISCOVER ARTEMIS →THE ARITHMETIC
Two products instead
of eight to ten.
Here is what that actually saves — calculated conservatively, at mid-market prices. To match the actives in ATHENA and ARTEMIS at comparable levels across single-ingredient products: a Bifida essence, a peptide serum, a Matrixyl serum, a bakuchiol treatment, an ectoin serum, niacinamide, hyaluronic acid — then the cream side: a ceramide barrier cream with cholesterol and phospholipids, an oil-soluble Vitamin C treatment, a caffeine product.
8 actives in ATHENA, 9 in ARTEMIS. $190 as a bundle.
Don't pay for more.
ATHENA, then ARTEMIS, under three minutes a day.
Fifteen to twenty minutes returned to every morning and every night is up to 16 waking days year. We did the math so your shelf doesn’t have to.
ATHENA & ARTEMIS →METHODOLOGY
Power through
architecture.
Multiple actives. Multiple pathways. Researched levels. Each choice disclosed.
Gentle and powerful are opposites.
That’s true when power comes from harshness — acids, high heat, irritation.
Ours comes from architecture: seventeen actives at researched doses, each on its own pathway, none fighting your skin. The result is two luxurious formulas, each complete on its own, made for skin as it changes.
Gentle enough to wear day and night.
Multiple Actives
Eight actives in ATHENA. Nine in ARTEMIS. Each with its own job — one mechanism per active, chosen to cohabit at skin-friendly pH, so everything works and everything belongs.
Multiple Pathways
Skin doesn’t age down one road, so we don’t formulate down one. Peptides for visible smoothing. Hydration and comfort. Antioxidant defense. And a phytoestrogen and bakuchiol, working complementary cosmetic pathways toward the same destination.
Researched Levels
Dosed at the levels supported by published research and supplier validation — and disclosed. Verifiable levels are the only levels that matter. The right dose is the researched dose — not the highest one.
ATHENA — BY THE NUMBERS
Eight actives.
No overlap in purpose.
Each of ATHENA’s eight actives was chosen for a role none of the others fills: smoothness, comfort, hydration. No filler, no doubling up, no overcrowding. Eight ingredients, eight reasons to be there, and room for each to work.
Actives in ATHENA.
Eight distinct roles, zero redundancy.
Bakuchiol protocol.
Day and night, at the 2019 comparison study’s own protocol.
Peptide solutions.
Argireline and Matrixyl 3000 at studied, supplier-validated levels.
The signature pair.
Phytoestrogen and bakuchiol reach skin morning and night.
ATHENA: THE SCIENCE
Every active.
Its pathway. Its role.

ARTEMIS: THE SCIENCE
Nine actives.
One discipline.
The cream follows the same evaluation — every active, its pathway, its role. Three signals, two layers of structure, two lines of defense, two quiet specialists. The pair ATHENA shares — a phytoestrogen and bakuchiol — appears here by design, not duplication. Everything else: one active per job.

Tested like
we mean it.
A formula is only as credible as the standards it continues to meet after launch.
Accelerated stability
12 weeks at 40°C / 75% humidity, with analytical retention testing on the oxidation-sensitive actives. The testing scenario speeds up the aging process by placing the formula under higher‑than‑normal temperature and humidity. This helps confirm early on that the product will stay safe, effective, and consistent throughout its shelf life.
Stability testing
Stability Testing exposes the formula to different temperatures and light conditions over time to make sure it stays safe, effective, and consistent in texture, color, and scent throughout its shelf life.
Preservative Efficacy Testing (PET)
PET is a safety test where the formula is intentionally exposed to microbes to make sure the preservative system can stop them from growing. It confirms the product stays safe, stable, and protected during real‑world use.
pH verification
pH Verification is a safety check where we measure the formula’s acidity to make sure it stays within a skin‑friendly range. This confirms the product remains balanced, gentle, and stable throughout its shelf life.
Human Repeat Insult Patch Test (HRIPT) - the gold standard
The HRIPT is an official, dermatologist‑supervised study where the product is applied to skin repeatedly over several weeks to confirm it doesn’t cause irritation or allergic reactions. We also test across all skin tones using the Fitzpatrick I–VI scale to ensure safety for every skin type.
GMP and ISO 22716 certified
Made in a U.S. facility registered with the FDA, following strict Good Manufacturing Practice: audited quality systems, full batch records, and traceability from raw material to finished bottle to give you highest confidence.
