YANNARA formulas are built on a documented four-layer structure with cluster-matched actives. Here's what each active is and what the published research shows at the molecule level — and where that evidence stops. What an ingredient is studied for is not a claim about what a serum will do for your skin. We hold that line because it's honest, and because it's more useful than a claim that overstates the research.
The actives we formulate with — each studied at the ingredient level, held separate from any promise about the finished serum.
If you're new to bakuchiol and want the foundation —
What bakuchiol is (and isn't), what the research says it does, whether "natural retinol" is a fair label, and how to use it — the plain-language starting point for everything else on this page.
Start here · the essentials Read the guide →If you're choosing between a retinol and a retinoid-free routine —
What bakuchiol is and isn't (it's not a form of vitamin A), how it compares to retinol in the clinical literature, who each approach suits, and how it fits inside Arawon's active complex.
In Arawon · 1% bakuchiol · retinoid-free Read the guide →If you're wondering what pairs safely with bakuchiol —
Why bakuchiol and vitamin C work well together, how it behaves with niacinamide and retinol, what not to over-stack, and whether it can cause purging — the layering guide.

What THDC is, how it compares to L-ascorbic acid, what the ingredient is studied for, and why an oil-soluble form makes sense inside a lipid-based serum.
Oil-soluble vitamin C ester Read the guide →If you've seen "pink microalgae" or Dunaliella salina on a label —
The salt-lagoon alga that makes its own antioxidants to survive intense light, why its colorless carotenoids work where coloured ones can't, what the studies show, and whether it clogs pores.
In Arawon · 1% · colorless carotenoids Read the guide →If you've seen willow bark sold as a natural BHA —
Why salicin is a precursor rather than salicylic acid itself, what the skin actually does with it, and what willow bark really offers — soothing and antioxidant support — for oily, blemish-prone skin.
In Banayad · the honest answer Read the guide →If you've been told to support your skin barrier —
What ceramides are and why they make up most of the barrier's lipids, why skin runs low on them with age and winter, the difference between water-based and anhydrous ceramide serums, and how to choose one.
In Panlunas · Ceramide NP + sphingolipids Read the guide →The same ingredient behaves differently in different formulas — the delivery context changes with the structure around it. YANNARA's actives are cluster-matched, then placed within a four-layer architecture. The actives are the evidence; the method is what gives them context.
It isn’t a theme. Algae survive conditions that would destroy most living things, and they do it by manufacturing their own protective chemistry. That chemistry is what we extract. Each YANNARA serum carries one, chosen for what its organism endures.
Two organisms, two survival strategies, one reason we use them. Neither is a sunscreen — what they offer is antioxidant support against everyday environmental stress. Read about the microalga →
