Give your skin more care, without adding more steps. 13°S Cellular Serum brings wild-harvested Kakadu Plum, Australian native botanicals and multi-weight Hyaluronic Acid into one lightweight daily formula.

For skin that looks dull, feels dehydrated or needs everyday barrier support, this is a simple place to start. Think brighter-looking skin, comfortable hydration and a fresh, lightweight finish.

What it does for your skin

• Supports visible radiance: Helps dull skin look brighter and promotes a more even-looking tone.
• Hydrates without heaviness: Helps skin feel hydrated and look plump, with a lightweight finish that layers comfortably under makeup.
• Brings calm and comfort: Helps soothe the look of redness and supports the skin barrier as part of your daily routine.

Why we chose these ingredients

Kakadu Plum · Our hero botanical for radiance
Kakadu Plum is recognised as one of the world’s richest natural fruit sources of vitamin C. This Australian native sits at the heart of our formula and our approach to brighter-looking skin.

Vitamin C is valued in skincare for its antioxidant properties, its role in supporting collagen formation and its potential to improve the appearance of uneven tone. Its performance in a finished serum depends on the form, concentration and stability of the vitamin C, not simply the amount naturally present in the fruit.

We chose Kakadu Plum as part of our radiance-focused botanical blend. Paired with Lilly Pilly, it supports brighter-looking skin and a more even-looking complexion, bringing a focus on fresh, luminous skin to your daily routine.

Lilly Pilly · A partner for radiance
We chose Lilly Pilly to complement Kakadu Plum in our brightening botanical blend. Together, they help address the appearance of dullness, making radiance a central focus of your everyday routine.

Multi-weight Hyaluronic Acid · Lightweight hydration
Chosen to help attract and retain moisture, Hyaluronic Acid supports hydrated, plumper-looking skin. Our multi-weight blend brings hydration into a lightweight formula, so skin feels cared for without a heavy finish.

Saltbush · Comfort and barrier support
This resilient Australian native was chosen for its role in supporting skin comfort. Alongside Infitrio™, it helps soothe the look of redness and support the skin barrier, balancing our focus on radiance with everyday care.

Infitrio™ · A complementary botanical blend
Combining Bitter Orange, Mountain Pepper Berry and River Mint, Infitrio™ complements the hero botanicals with a focus on skin comfort and barrier support. It helps round out a formula designed to care for skin, not just brighten its appearance.

Glycerin · Moisture support
Glycerin helps attract moisture to the skin. Alongside Hyaluronic Acid, it supports the formula’s hydration focus and helps skin feel soft and comfortable.

Carefully extracted botanicals

Choosing remarkable ingredients is only the beginning. Cellular Extraction™ uses targeted high pressure rather than heat to capture each plant’s water-soluble compounds, the botanical components that dissolve in water and become part of our formula.

Our approach brings radiance, hydration and skin comfort together in one daily serum, rather than asking you to build a complicated routine.
