Why's this serum so special?
Your skin is losing what it needs
As we age, our skin stops producing natural oils — leaving it duller, less even and more prone to fine lines and dark spots.
Tallow puts it back
Tallow contains lipids identical to the oil we produce ourselves — a skin food that replenishes what's going missing and primes your skin to absorb actives.
Your skin soaks it up — and everything in it
Because your skin recognises tallow, it readily accepts the actives we've added — Azelaic Acid, Niacinamide, Centella Asiatica and Hyaluronic Acid — for a smoother, brighter, more even-looking complexion.
A winning combo for smoother, more even-looking skin.

From the Founder
"The serum is where the real work happens. I wanted something lightweight that you'd barely feel, but that quietly helps your skin look its best over time."
Curtis Fairweather · Founder
We knew tallow alone wasn't enough for this. So we partnered with one of NZ's most awarded cosmetic formulators — someone who's spent decades developing for some of the world's largest billion-dollar beauty brands — then hired specialist in-house staff to manufacture every batch to the highest standard.
It's high-performance cosmetic skincare, built to a level the NZ tallow industry has never seen — 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."
Glow, tone and hydration — in one formula
Most serums force a trade-off — an acid for brightening, or a humectant for hydration. This formula combines both in a single, stable base that works across all three complexion concerns: more even-looking tone, plumper-looking texture, and deeper hydration.
The bio-identical lipid base carries these actives into the skin's surface, helping the formula feel effective with less product. Lightweight enough to layer comfortably under both Day and Night Cream.
🍬 Azelaic Acid
A gentle but effective acid; studies on azelaic acid suggest it can help skin look more even in tone and reduce the look of post-inflammatory marks.
🔬 Niacinamide (B3)
Works in several ways — helping skin feel conditioned and comfortable, helping skin look more even in tone, and supporting a calmer-looking complexion.
🌱 Centella Asiatica
The active triterpenoids of Cica. Studies on Centella Asiatica suggest it can help skin look firm and plump for a smoother, more youthful-looking complexion.
💧 Hyaluronic Acid
Low molecular weight HA that hydrates effectively, helping skin look plump and stay hydrated and comfortable.
A Timeline Based on the Research
What published ingredient research suggests with twice-daily serum use — 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. Azelaic Acid starts gently refining uneven surface areas for a more even-looking complexion.
Niacinamide and Licorice Root help skin look progressively more even in tone. Post-inflammatory marks, uneven patches and sun damage begin to look more even.
Studies on Centella Asiatica suggest it can help skin look firm and plump. Fine lines appear softer and skin has a more elastic, resilient quality with continued use.
Individual results vary. Timeline based on published studies for each key active at relevant concentrations.
