A lightweight serum that brings back radiance β actives carried on a bio-identical tallow base so your skin absorbs them, instead of letting them sit on the surface.
Glow you can see from day one
As skin ages it stops making the oils that give it life and light. The tallow base replenishes what's going missing while carrying niacinamide and hyaluronic acid deeper β for a glow you can see from day one, building with use.
Immediate and building radiance β visible glow from the first application.
"Goes into the skin seamlessly β my face looks lit-from-within after the first use."

Skin loses its light as it ages
Sebum production drops, surface texture roughens, and the way light reflects off your face changes. The result is dullness β even when skin is otherwise healthy.
Tallow replenishes the lipids that catch the light
Tallow's lipid profile mirrors your own skin's, so it absorbs and restores the natural surface that gives healthy skin its glow β no greasy finish.
Hyaluronic acid plumps the surface instantly
Low molecular weight HA draws moisture into the upper layers, smoothing micro-texture so light bounces back the way it does on younger skin.
Glow from day one β building with continued use.

From the Founder
"The serum is where the real work happens. I wanted something lightweight that you'd barely feel, but that quietly transforms your skin over time."
Curtis Fairweather Β· Founder
We knew tallow alone wasn't enough for this. So we partnered with one of NZ's most awarded cosmetic formulators β someone who's spent decades developing for some of the world's largest billion-dollar beauty brands β then hired specialist in-house staff to manufacture every batch to the highest standard.
It's cosmeceutical skincare, built to a level the NZ tallow industry has never seen β and it all starts with the ingredient your skin already trusts.

"The texture is super-smooth and light. With tallow's oils being so similar to our own skin, it feels like it enhances rather than changes it."
Most "glow" serums are water + glycerin β they hydrate the very top layer of the skin and that's it. The shine fades within an hour. This formula sits on a tallow base that mirrors your skin's own lipid profile, so the hydration and the radiance-supporting actives go deeper and stay longer.
Light enough to layer under both Day and Night Cream β and SPF the next morning.
Low molecular weight HA penetrates beyond the surface, smoothing micro-texture so light reflects more evenly β immediate visible plumping.
Refines the look of pores and surface texture β a smoother surface reflects light better, which reads as a more radiant complexion.
The active triterpenoids of Cica. Calms surface irritation and supports a healthy-looking, even-toned complexion.
Gently refines the surface and supports more even-looking tone β the foundation any radiance sits on top of.
What published ingredient research suggests with twice-daily serum use β and when.
Fast-absorbing formula delivers immediate surface hydration. Many people notice visible radiance from the first application as Hyaluronic Acid plumps the surface quickly.
Niacinamide begins working on the appearance of pores and surface texture. The smoother the surface, the more light it reflects.
Azelaic Acid and Niacinamide together support a more even-looking complexion β the foundation that radiance sits on.
Centella Asiatica supports a calmer, healthier-looking complexion. The combined effect across all four actives reads as a noticeably more radiant face.
Individual results vary. Timeline based on published studies for each key active at relevant concentrations.
