Real Actives, Made Gentler for Sensitive Skin

Niacinamide, Azelaic Acid & Hyaluronic Acid in a tallow โ€” formulated to sit more gently on sensitive, reactive skin than the harsh bases actives usually come in. 15ml

First of its kind in NZ

If a big-brand routine ever left your skin worse, the problem was often the harsh, synthetic base โ€” not the actives themselves. Reviana delivers Niacinamide, Azelaic Acid, Centella Asiatica and Hyaluronic Acid in a bio-identical tallow, designed to be gentler on sensitive, reactive skin than the harsh, synthetic bases actives usually come in.

No harsh fillers. No synthetic fragrance. Just actives your skin recognises.

"A really fresh, clean smell โ€” the texture is super-smooth and light."

Why's this serum so special?

Harsh routines made it worse

Big-name, 10-step routines packed with synthetic fillers and fragrance can leave sensitive skin red, irritated and breaking out โ€” and it's easy to blame the actives.

It was never the actives โ€” it's the base

Niacinamide and Vitamin C didn't wreck your skin. The harsh, synthetic base delivering them did. Change the base and you can keep the actives.

Tallow is a base your skin recognises

Tallow shares a similar lipid structure to your own skin โ€” so even sensitive, reactive skin tends to take to it more easily than to harsh, synthetic bases, while it carries the actives in: Azelaic Acid, Niacinamide, Centella Asiatica and Hyaluronic Acid.

Real actives on a base made gentler for sensitive skin โ€” for clearer-looking, calmer, more resilient-looking skin.

Full Ingredient List

Aqua, Glycerin, Azelaic Acid, Niacinamide, Benzyl Alcohol (and) Dehydroacetic Acid, Polyacrylate Crosspolymer-6 (and) t-Butyl Alcohol (and) Water, Panthenol, Tallow, Glycyrrhiza Glabra (Licorice) Root Extract, Parfum (Aloe & Cucumber LC), Asiaticoside (and) Madecassic Acid (and) Asiatic Acid, Sodium Hyaluronate, Bisabolol, Tocopherol (and) Helianthus Annuus (Sunflower) Seed Oil, Sodium Phytate (and) Aqua (and) Alcohol, Sodium Citrate, Aloe Barbadensis Leaf Extract.

From the Founder

Curtis

"So many people think their sensitive skin can't handle actives. It often can โ€” it's usually the harsh base they're delivered in that's the real problem. Put them in tallow your skin already knows, and it can be a different story."

Curtis Fairweather ยท Founder

We knew tallow alone wasn't enough for this. So we partnered with one of NZ's most awarded cosmetic formulators โ€” someone who's spent decades developing for some of the world's largest billion-dollar beauty brands โ€” 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 โ€” and it all starts with the ingredient your skin already trusts.

The Science

Real actives, gentler on reactive skin

The actives that brighten, smooth and even out skin โ€” Niacinamide, Azelaic Acid โ€” are the same ones harsh, water-and-alcohol bases tend to deliver in a way sensitive skin can react to. Reviana puts them in a bio-identical tallow your skin recognises, giving even reactive, easily-irritated skin a gentler base to use them on.

That tallow helps carry these actives into the skin's surface more readily than water-based serums โ€” supporting clearer, calmer, more even-looking skin with less product, and skipping the synthetic fillers and fragrance that can flare sensitive skin. Lightweight enough to layer under both Day and Night Cream.

๐Ÿฌ Azelaic Acid

A gentle but effective acid โ€” supports clearer, more even-looking skin and softens the look of marks and redness, and is typically gentler than harsher AHAs.

๐Ÿ”ฌ Niacinamide (B3)

Helps condition the skin โ€” helping support the look of the skin's moisture barrier, helping balance the look of oily areas and calming the look of redness for a clearer, calmer-looking complexion.

๐ŸŒฑ Centella Asiatica

The active triterpenoids of Cica โ€” long used to soothe reactive, irritated skin and support a smoother, calmer-looking complexion.

๐Ÿ’ง Hyaluronic Acid

Low molecular weight HA that hydrates effectively โ€” helping a strong active line-up feel less likely to leave sensitive skin tight or stripped.

What to Expect

A Timeline Based on the Research

What published ingredient research suggests with twice-daily serum use โ€” and when.

Day 1
Immediately
Hydrated, not stripped

The tallow + Hyaluronic Acid hydrate fast, so even a real active line-up is less likely to leave reactive skin feeling tight, dry or irritated from the first use.

Wk 1
Week 1
Settling in gently

Because the base is one your skin recognises, sensitive skin tends to settle in more gently โ€” barrier-supporting Niacinamide helps keep it calm as the actives get to work.

Wk 4
Week 4
Clearer-looking skin

Azelaic Acid and Niacinamide progressively support clearer-looking, more even skin โ€” and the look of marks, redness and uneven patches begins to soften.

Wk 8+
Week 8+
Calmer, more even complexion

With continued daily use, skin can look calmer and more even โ€” softer-looking marks, and the more resilient feel of a barrier that's no longer up against a harsh base.

Individual results vary. Timeline based on published studies for each key active at relevant concentrations.
