The First Batch Has a Date: Introducing CS26-B01

At Thirteen Degrees South, we reject the conventions of mass production. To ensure every drop reaches your skin at its peak biological activity, our formulations are produced exclusively in strictly limited micro-batches.

18 Months in the Making: The Journey to the 13th Parallel

Batch CS26-B01 is the culmination of 18 months of rigorous research and development. It represents a journey that took our founders deep into the arid Red Centre and across the rugged topography of the Top End. We went to study the raw resilience of native botanicals thriving in some of Australia's most extreme, sun-drenched environments.

What grows under that intense heat, relentless UV exposure, and ancient soil profile does not simply survive—it thrives. These plants adapt by synthesising extraordinary biological intelligence to protect their own cellular walls.

We went to find that resilience. We brought it back for your skin.

The Experience: The Radiance of Resilience

A definitive treatment engineered for the demands of the modern complexion. The 13°S Cellular Serum delivers a concentrated surge of vitality, working in quiet harmony with your skin to restore its natural brilliance, clarity, and structural strength.

• Illuminated Texture: Refines and firms the skin's surface, revealing a complexion that is consistently clear, smooth, and vibrant.

• Fortified Balance: Instantly calms and stabilises redness, reinforcing your natural skin defenses against the toll of daily environmental fatigue.

• Deep Immersion: Softens and hydrates at a cellular level for a finish that is perpetually dewy, plump, and supple.

The Sensory Profile: An ultra-lightweight, fluid texture optimized for rapid, flash-absorption. It brightens, plumps, and protects, leaving a weightless, resilient, all-day glow.

The Cellular Compound Architecture

The true efficacy of CS26-B01 lies in our extraction method. By utilising advanced Cellular Extraction™, we mirror the plant's internal chemistry, delivering living native nutrients in a bio-identical form.

01 / The Brighteners

• Kakadu Plum (Terminalia Ferdinandiana): The world's premier source of Vitamin C, boasting an antioxidant profile up to 100x greater than traditional citrus. It works synergistically to promote radiance, support natural collagen production, and offer advanced environmental defence.

• Lilly Pilly (Syzygium Leuhmannii): Rich in anthocyanins to smooth, polish, and gently refine the skin's surface texture.

02 / The Protectors

• Saltbush (Atriplex nummularia): A mineral-rich desert powerhouse that intensely fortifies the lipid barrier and supports the skin's natural defense mechanisms.

• Infitrio™ Blend: Our proprietary botanical complex of Bitter Orange, Mountain Pepper Berry, and River Mint. This trio delivers potent anti-inflammatory, calming, and free-radical scavenging action.

03 / The Hydrators

• Multi-Weight Hyaluronic Acid (HA): Holds up to 1,000x its weight in water. It acts as a deep-penetration vehicle, drawing the native cellular extracts deep into the epidermis for an instant plumping, line-smoothing finish.

04 / The Aromatics

• Neroli & Southern Rosalina (Melaleuca ericifolia): While Neroli promotes cellular renewal with an uplifting floral note, Southern Rosalina—a ultra-gentle native alternative to traditional Tea Tree—grounds the blend with a purifying, herbaceous balance.

A Conviction of Absolute Integrity

Batch CS26-B01 is not a product of commercial compromise. Every compound selected, every extraction performed, and every micro-batch controlled is a direct expression of a singular philosophy:

"I have always believed that true luxury is a byproduct of absolute integrity. In the frontier we are defining, there is no room for the superficial."
