Some ingredients are found. Ours are earned.
Along the 13th parallel south (13°S), where extremes forge resilience, our hero ingredient thrives. Wild-harvested Kakadu Plum — the world's richest natural source of Vitamin C — is captured at full potency through Cellular Extraction™ technology, delivering bio-available actives deep into the skin's cellular matrix.
From red dirt to laboratory, we maintain uncompromising ingredient integrity in small, quality-verified batches. The land has done the work for millennia. We simply refuse to get in the way.
13°S Cellular Serum is a definitive treatment for the modern, climate-stressed complexion. The result: visibly brighter, firmer skin with restored radiance. Native Lilly Pilly and multi-weight Hyaluronic Acid lock in lasting hydration, while Saltbush and the Infitrio™ Blend fortify the skin's natural barrier against environmental stressors.
Clean Beauty Certified. Free from silicones, synthetic fragrance, and unnecessary fillers. Suitable for all skin types.

Why Your Skin Doesn't Need a 7-Step Routine
Replaces 3 Serums in One Step
Stop layering different bottles and risking active ingredient conflicts. Our 13°S Cellular Serum combines high-potency Vitamin C, multi-weight Hyaluronic Acid, and barrier-repairing Saltbush into one stabilised, synergistic formula. No burning, no pilling, no chemical clashes.
Cold-Extracted for Real Bio-Availability
Budget serums use synthetic ascorbic acid that oxidizes into useless brown liquid within weeks. We use heat-free Cellular Extraction™ on wild Kakadu Plum harvested along 13°S latitude. This preserves the plant's intact phyto-complex, delivering stable, natural Vitamin C deep into the skin rather than sitting on top of it.
Effortless Layering & Lightweight Touch
No sticky residue. No waiting 10 minutes before applying makeup. Formulated as a silky, fast-absorbing botanical fluid, it glides on smoothly, absorbs instantly, and pairs effortlessly with your favourite moisturiser and SPF without pilling or clogging pores.
Premium Care That Sustains Itself
An $89 skincare investment shouldn't turn into a financial burden. Invest in the initial glass bottle once. Every order unlocks 20% off your 30ml Refills ($71.20 with 20% discount) — delivered in sealed bottles with a 30-second pump-swap design. Less waste, lower recurring cost, zero compromises.
