Alpha Arbutin

What it does in skin
A targeted brightening active that helps reduce the appearance of discolouration by influencing tyrosinase activity in the melanin pathway. It supports a more even-looking tone without the "peel-like" irritation profile of stronger resurfacing systems.

What you'll notice
Gradual fading of post-breakout marks and uneven tone with consistent daily use. Results are typically progressive rather than immediate.

Why we use it
We choose alpha arbutin for its efficacy-to-tolerability balance—especially important in routines designed for sensitive or barrier-compromised skin.

Reference: Sugimoto K et al. J Dermatol. 2004.

Ascorbic Acid (Vitamin C)

What it does in skin
A potent antioxidant that helps neutralise oxidative stress from UV and pollution, supports collagen synthesis, and contributes to visible radiance. Ascorbic acid is the biologically active form of vitamin C, which is why it can be highly effective when properly stabilised.

What you'll notice
Improved glow, smoother look to skin texture, and brighter appearance over time—especially when used consistently with daily sunscreen.

Why we use it
We use it because it's one of the most evidence-supported actives for photodamage support—formulated with barrier respect and stability in mind.

Reference: Humbert PG et al. J Am Acad Dermatol. 2003.

Australian Wild Rosella

What it does in skin
Hibiscus sabdariffa is a tropical hibiscus grown across northern Australia, naturalised here for thousands of years after arriving through Makassan trade. Its calyx is rich in anthocyanins, organic acids and polyphenols, which contribute antioxidant activity and a light conditioning effect.

What you'll notice
A softer, more comfortable skin feel after cleansing, without heaviness or residue.

Why we use it
We infuse the flower into sunflower oil ourselves rather than buying a pre-made extract, which keeps the infusion fresh and lets us control its strength. It's also an Australian-grown botanical, which matters to us more than sourcing a fashionable import.

Reference: Cho WK et al. Int J Mol Sci. 2023.

Azelaic Acid

What it does in skin
A dicarboxylic acid produced naturally on skin by Malassezia yeasts. It works along several pathways at once including antibacterial activity, inhibition of tyrosinase in the melanin pathway to even tone without lightening skin that doesn't need it. It also modulates inflammation and redness.

What you'll notice
Refined texture, calmer-looking redness, and gradual fading of post-blemish marks. A mild tingle on first use is common and usually settles within a few weeks.

Why we use it
Azelaic acid is only about 0.24% soluble in water, so at 10% there is no dissolving it — it has to be suspended, and the particle size becomes the delivery system. We use a micronised grade (1–10 µm range) because they easily get deposited into the follicles which is where they do their magic. Adding solvent to force more into solution is the obvious move and the wrong one: a saturated suspension is already at maximum activity, and anything dissolved can recrystallise into coarse crystals on the shelf. We run it at pH 4.7 for the same reason the original manufacturers did — more total active reaches skin there than at a lower pH, and it's gentler.

Carnosine

What it does in skin
Carnosine is a naturally occurring dipeptide antioxidant that helps neutralise reactive carbonyl species involved in glycation—a process where sugar molecules bind to collagen and elastin, contributing to stiffening and loss of resilience over time.

What you'll notice
Supported skin firmness and resilience with consistent long-term use, working alongside other antioxidants rather than replacing them.

Why we use it
Glycation is a distinct ageing mechanism from oxidative stress or UV damage, so carnosine addresses a gap that Vitamin C and Vitamin E alone don't cover.

Reference: Hipkiss AR. Adv Food Nutr Res. 2009.

Centella Asiatica

What it does in skin
Centella asiatica contains triterpenoid compounds—including asiaticoside and madecassoside—that support collagen synthesis, wound healing, and calming of irritated or reactive skin.

What you'll notice
Reduced visible redness and improved comfort, particularly helpful for reactive, sensitised, or barrier-compromised skin.

Why we use it
It's one of the most well-established soothing and repair-supportive botanicals available, making it a natural fit for our barrier-focused formulas.

Reference: Bylka W et al. Phytother Res. 2014.

Ceramides NP/AP/EOP

What it does in skin
Ceramides are essential barrier lipids that help form the "mortar" between skin cells. They support reduced transepidermal water loss and improve barrier resilience. When skin is dry, reactive, or over-exfoliated, replenishing ceramides can meaningfully improve comfort and recovery.

What you'll notice
Less tightness, less flaking, and improved tolerance to active routines. Skin often feels more stable and less reactive.

Why we use it
Barrier repair isn't just "moisture"—it's lipid architecture. Ceramides are foundational for long-term barrier function, not a short-term cosmetic fix.

Reference: Elias PM. J Am Acad Dermatol. 2008.

Cholesterol

What it does in skin
Cholesterol is a natural component of the skin barrier and works synergistically with ceramides and fatty acids to support a more complete lipid matrix. This helps the barrier function as a flexible, cohesive structure rather than a fragile surface film.

What you'll notice
Improved comfort, reduced dryness "rebound," and better tolerance when using retinoids, exfoliants, or brightening actives.

Why we use it
We include cholesterol because ceramides perform best in a balanced lipid system—supporting skin physiology rather than only surface feel.

Reference: Elias PM. J Invest Dermatol. 2012.

Ectoin

What it does in skin
Ectoin is an extremolyte that helps skin manage environmental stress by supporting hydration, reducing reactivity, and helping maintain cellular comfort. It's often used for sensitised skin, post-procedure routines, and climates that drive dehydration or irritation.

What you'll notice
Skin feels calmer and less "hot" or reactive. Hydration feels more stable, especially when weather or active use would normally trigger dryness.

Why we use it
Because hydration isn't just water content—it's stress resilience. Ectoin supports a more tolerant skin environment for active routines.

Reference: Graf R et al. Clin Cosmet Investig Dermatol. 2019.

Fatty Acids

What it does in skin
Fatty acids contribute to barrier flexibility and help support a healthy lipid structure. They can also improve the feel of dryness by restoring softness and reducing roughness.

What you'll notice
Skin feels smoother and more comfortable, with less "paper-dry" texture over time.

Why we use it
Barrier repair works best as a trio: ceramides + cholesterol + fatty acids. We aim for support that is biomimetic, not just occlusive.

Reference: Proksch E et al. Exp Dermatol. 2008.

Ferulic Acid

What it does in skin
Ferulic acid is an antioxidant that helps neutralise free radicals and can improve the stability and performance of antioxidant systems—especially vitamin C and vitamin E.

What you'll notice
Improved clarity and resilience against environmental stress, particularly in daytime routines when paired with sunscreen.

Why we use it
We use ferulic acid as a performance enhancer—supporting antioxidant synergy rather than relying on a single ingredient to do everything.

Reference: Lin FH et al. J Invest Dermatol. 2005.

Hyaluronates

What it does in skin
Hyaluronates are water-binding molecules that support hydration, comfort, and a smoother skin surface. Different forms vary by molecular size and structure, which influences how they sit on the skin, how they retain water, and how long the hydration feels sustained.

What you'll notice
Immediate softness and reduced tightness, with a more "cushioned" feel over time. Skin looks more supple and makeup tends to sit more evenly on well-hydrated skin.

Why we use multiple forms
Skin naturally contains hyaluronic acid in a range of sizes. A multi-form system mirrors this by combining surface-hydrating, longer-lasting, and skin-affinitive hyaluronates. The goal isn't "more for the sake of more"—it's layered hydration with better comfort and less dehydration rebound, particularly for active users or compromised barriers.

Reference: Pavicic T et al. Dermatology. 2011.

Hypochlorous Acid (HOCl)

What it does in skin
A molecule your own immune system makes — neutrophils produce it as part of the innate immune response, which is why skin tolerates it so well. It reduces surface bacterial load, including Staphylococcus aureus and Cutibacterium acnes, and helps calm inflammation in conditions such as acne, rosacea, perioral dermatitis and eczema.

What you'll notice
Skin feels calmer and less reactive, without the dryness or stinging that usually comes with antibacterial actives.

Why we use it
Formulated at pH 4–5.5, where it stays as hypochlorous acid rather than the harsher hypochlorite ion. The vehicle is essentially water — no surfactants, emulsifiers or preservative system — so for reactive or barrier-compromised skin there's very little left in the formula to react to.

Lactobionic Acid

What it does in skin
Lactobionic acid is a polyhydroxy acid (PHA) that supports gentle exfoliation with added humectant benefits. Its larger molecular structure generally contributes to slower penetration and better tolerance.

What you'll notice
Improved smoothness and brightness with less irritation potential—often well suited to sensitive skin or those new to acids.

Why we use it
We use PHAs when the goal is refinement without barrier disruption—helping maintain comfort while improving surface texture.

Reference: Green BA et al. Cutis. 2009.

Macadamia Oil

What it does in skin
Macadamia oil is a nourishing emollient oil rich in unique fatty acids that help soften and condition the skin. It contributes to a plush, comforting feel in the Lanolin & Vitamin D Barrier Ointment.

What you'll notice
Skin feels supple and cushioned with a non greasy feel.

Why we use it
We include macadamia oil to bring richness and barrier-friendly comfort especially for skin that can feel dry, tight, or sensitised.

Mandelic Acid

What it does in skin
Mandelic acid is a slower-penetrating AHA, often favoured for acne-prone or discolouration-prone skin due to its gentler profile. It can support smoother texture while reducing the likelihood of stinging compared with smaller AHAs.

What you'll notice
Gradual improvement in texture, clarity, and the look of congestion—typically with a more comfortable feel than stronger exfoliation options.

Why we use it
A smart AHA choice when you want resurfacing but need a measured approach that respects the barrier.

Reference: Wishart JM et al. J Cosmet Dermatol. 2018.

N-Acetyl Glucosamine

What it does in skin
N-acetyl glucosamine supports hydration and barrier function and is also used to help improve the appearance of uneven tone—particularly when paired with niacinamide.

What you'll notice
Improved comfort and a more even-looking tone over time, with a gentle, non-stripping feel.

Why we use it
It's a true multi-tasker: barrier-supportive and brightening-supportive, making it ideal in routines built for sensitive or reactive skin.

Reference: Bissett DL et al. Br J Dermatol. 2004.

Niacinamide

What it does in skin
Niacinamide supports barrier function, helps reduce visible inflammation, and can improve the appearance of pores, oil imbalance, and uneven tone. It's widely used because it performs across multiple concerns with strong tolerability when correctly formulated.

What you'll notice
Calmer-looking skin, improved clarity, and a smoother appearance to pores over time. Many people also notice improved resilience during active routines.

Why we use it
It's one of the best all-round barrier-first actives, making it suitable for pigmentation-prone, acne-prone, and sensitive skin profiles.

Reference: Draelos ZD. Dermatol Surg. 2006.

Panthenol (Provitamin B5)

What it does in skin
Panthenol converts to pantothenic acid within the skin and functions as a humectant and emollient, supporting barrier repair, hydration retention, and reducing transepidermal water loss. It also has documented soothing and wound-healing properties.

What you'll notice
Calmer, more comfortable skin with improved hydration and a softer overall texture.

Why we use it
It's a well-tolerated, multi-tasking ingredient that pairs naturally with ceramides and ectoin as part of a broader barrier-support strategy.

Reference: Ebner F et al. Am J Clin Dermatol. 2002.

PDRN (Polydeoxyribonucleotide)

What it does in skin
PDRN is derived from purified DNA fragments and works via activation of the adenosine A2A receptor pathway, stimulating fibroblast activity, collagen synthesis, and tissue repair. It's widely used in regenerative and post-procedure skincare.

What you'll notice
Improved skin resilience and smoother texture over time, particularly supportive for compromised, reactive, or slow-recovering skin.

Why we use it
Its mechanism is genuinely regenerative rather than purely occlusive or humectant, making it a meaningful addition alongside our ceramide-led barrier repair formulas.

Reference: Kim JH et al. Arch Pharm Res. 2013.

Retinal

What it does in skin
Retinal (retinaldehyde) supports skin renewal and collagen pathways and is generally considered more efficient than retinol because it converts to retinoic acid in fewer steps. Effective retinoid results depend on controlled formulation and consistent use.

What you'll notice
Smoother texture, clearer-looking pores, and visible improvement in fine lines over time. Some users may experience early dryness or flaking during adjustment.

Why we use it
We choose retinal for high efficacy, then build the surrounding formula to prioritise tolerance—because results only matter if skin can comfortably stay consistent.

Reference: Saurat JH et al. Dermatology. 1994.

Rice Bran Oil

What it does in skin
Rice bran oil is a lightweight botanical oil rich in skin-conditioning fatty acids and naturally occurring antioxidant components. It helps soften the skin and support a comfortable barrier feel.

What you'll notice
Skin feels softer, smoother with a lightweight finish in ther Ceramide balm.

Why we use it
We use rice bran oil as a conditioner without weight and heaviness that many natural oils have.

References: Zamil DH et al. J Cosmet Dermatol. 2022;21(11):6056–6060. · Manosroi A et al. Pharm Biol. 2012;50(2):208–224.

Salicylic Acid

What it does in skin
Salicylic acid is a BHA that helps clear congestion by working within oily pores. It supports reduced blackheads and breakouts by improving the shedding of pore-lining cells.

What you'll notice
Clearer pores, fewer blackheads, and smoother texture—often with improved oil control over time.

Why we use it
It's a gold-standard ingredient for congestion, but we pair it with barrier support because overuse can drive dryness or irritation.

Reference: Kligman AM. J Dermatol Treat. 1992.

Shea Butter

What it does in skin
Rich in fatty acids and triterpenes, shea butter supports barrier lipid replenishment and has documented anti-inflammatory activity, contributing to a cushiony, protective skin feel.

What you'll notice
Softer, more comfortable skin with reduced dryness, particularly on areas prone to tightness or flaking.

Why we use it
It works synergistically with ceramides and cholesterol in our biomimetic barrier balm, contributing richness without feeling heavy or occlusive.

Reference: Alander J. Lipid Technol. 2004.

Sodium Polyglutamate

What it does in skin
A naturally derived humectant biopolymer that forms a moisture-retentive film on the skin's surface, capable of holding significantly more water than hyaluronic acid at equivalent concentrations.

What you'll notice
Enhanced surface hydration and a smoother after-feel, particularly noticeable in barrier-support formulas.

Why we use it
It complements our multi-form hyaluronate system by adding a further humectant mechanism, supporting hydration from a different angle.

Reference: Shukuwa T et al. J Cosmet Sci. 2006.

Squalane

What it does in skin
A stable, saturated hydrocarbon that closely mimics skin's own sebum, providing lightweight emollience without clogging pores.

What you'll notice
Softer, smoother skin without heaviness or greasiness—suited to both dry and oily skin types.

Why we use it
It's biomimetic and non-comedogenic, making it well suited to acne-prone and sensitive skin alike, and a natural fit within our barrier repair formulas.

Reference: Huang ZR et al. Molecules. 2009.

Sunflower Seed Oil

What it does in skin
Helianthus annuus seed oil is high in linoleic acid, the fatty acid skin uses to build acylceramides — a structural component of the barrier itself. Skin low in linoleic acid tends toward roughness and reactivity.

What you'll notice
A light, non-greasy finish with skin feeling conditioned rather than coated.

Why we use it
It's the carrier for our rosella infusion, chosen over heavier oleic-dominant oils. Comparative work on adult skin found sunflower seed oil preserved barrier integrity where olive oil measurably disrupted it — a useful reminder that "natural oil" is not one category.

Reference: Danby SG et al. Pediatr Dermatol. 2013.

Tranexamic Acid

What it does in skin
Tranexamic acid supports the appearance of more even tone by influencing pigment signalling pathways and helping reduce inflammation-driven pigmentation triggers. It's commonly used in routines targeting melasma and post-inflammatory hyperpigmentation (PIH).

What you'll notice
Gradual fading of stubborn marks and a more even-looking complexion with consistent use over weeks.

Why we use it
It's effective and pairs exceptionally well with niacinamide, N-acetyl glucosamine, and arbutin—supporting results without relying on aggressive exfoliation.

Reference: Lee JH et al. J Dermatolog Treat. 2016.

Vitamin E (Tocopherol)

What it does in skin
Tocopherol is a lipid-soluble antioxidant that supports barrier lipids and helps reduce oxidative stress. It also complements vitamin C systems and supports product stability.

What you'll notice
Improved skin feel and resilience, particularly in routines focused on antioxidant protection and barrier support.

Why we use it
We use vitamin E both for skin benefit and as part of a well-designed antioxidant network—especially alongside ferulic acid.

Reference: Thiele JJ et al. J Mol Med. 2001.

Zinc PCA

What it does in skin
Zinc PCA helps support oil regulation and contributes to a healthier skin environment by supporting microbial balance. It's often used in acne-prone routines alongside anti-inflammatory barrier support.

What you'll notice
Less shine, improved clarity, and calmer-looking breakouts over time.

Why we use it
It complements niacinamide and BHA routines by supporting oil control without aggressive stripping.
