Redefine your skin's radiance — on a cellular level.

Some serums sit on the surface. The Lime Caviar Face Serum goes deeper. Formulated with Certified Organic Finger Lime Caviar Cellular Extract — Australia's most prized native botanical — this transformative serum penetrates deeply to enhance cell vitality, stimulate collagen and elastin production, and deliver a visible lift and luminosity that builds with every use.

This is not just brightening. This is skin redefined.

 

How It Works

The bioactive compounds and organic acids extracted from Finger Lime Caviar work on a cellular level interacting with skin to optimise and accelerate skin renewal, repair damaged cells, and restore the skin's natural radiance. Combined with Niacinamide (Vitamin B3), the formula becomes a powerhouse — potent enough to penetrate deeply, regulate oil production, minimise pores, and visibly even skin tone while strengthening the skin barrier from within.

Rich in natural AHAs, the serum gently resurfaces the skin's surface, dissolving dull, congested cells to reveal the fresher, brighter skin beneath. Meanwhile, the Vitamin C and antioxidants in Lime Caviar neutralise free radical damage and protect against environmental stressors — contributing to the skin's long-term health, firmness, and glow.

 

Powered by Nature

Brightens and evens skin tone — Vitamin C-rich Finger Lime Caviar and Niacinamide work together to visibly fade dark spots, reduce hyperpigmentation, and deliver a luminous, even complexion.

Stimulates collagen and elastin — promotes cellular turnover and supports the skin's structural proteins for a visibly firmer, more lifted appearance over time.

Deeply hydrates and plumps — AHAs and bioactive compounds restore moisture levels and smooth the skin's surface for a supple, dewy finish.

Repairs and protects — antioxidants neutralise free radical damage and support the skin barrier, reducing the appearance of imperfections and preventing future damage.

Minimises pores and refines texture — Niacinamide visibly tightens pores and smooths uneven texture for a visibly perfected finish.

 

The Experience

Apply a few drops to cleansed, toned skin and feel the silky, fast-absorbing formula melt effortlessly into the skin — no heaviness, no residue. With regular use, skin looks visibly brighter, smoother, and more lifted, with imperfections fading and natural radiance taking centre stage.

 

Proudly Australian-made. Certified organic key ingredients. Dermatologist-tested. Because your skin deserves nothing less than extraordinary.

Key Ingredients

*Microcitrus Australasica Fruit Cellular Extract (Lime Caviar Extract)

(Also known as Finger Lime) carry a potent source of natural Vitamin C, Vitamin E, Polyphenols, Tryptophans, Ferulic Acid and Citrus Flavonoids Poncirin and Limocitrins.

Polyphenols benefit the skin by acting as powerful antioxidants that protect against premature aging and environmental damage. They can also improve skin texture by boosting collagen production, brighten the complexion by reducing hyperpigmentation, and soothe inflammation.

Tryptophans support hydration, firmness, and repair through its roles in providing moisture, collagen synthesis, antioxidant and anti-inflammatory effects.
It helps the skin stay hydrated by improving barrier function and elasticity, strengthens the skin structure by promoting collagen production, reduce irritation and protect against environmental and UV damage.

Ferulic Acid reduces signs of aging such as fine lines and wrinkles, evens skin tone by minimising dark spots and redness, and boosts the stability and effectiveness of vitamins C and E.

Poncirins neutralise free radicals caused by UV radiation and environmental pollutants, helping to prevent premature skin aging and tissue deterioration. By supporting overall cell health, poncirin preserves your skin's youthful radiance.

Limocitrins act as potent antioxidants that combat environmental damage, reduce inflammation, promote a brighter complexion, counteracts skin aging caused by sun damage and supports youthful, elastic skin. Prevents oxidative stress and slows the onset of fine lines and wrinkles.

Phenolics your skin faces daily attacks from UV rays and pollution. Phenolics intercept these free radicals at the cellular level -
protecting collagen and DNA before damage can occur.

All are powerful antioxidants that neutralise free radicals and oxidative stress and guard your skin from damaging environmental factors such as UV radiation.

Niacinamide B3 + Lime Caviar

Niacinamide (Vitamin B3) is a versatile, skin-friendly ingredient that strengthens the moisture barrier, balances oil production, and minimises the look of pores. It visibly fades dark spots, reduces redness, and smooths overall texture.

Controls Oil and Minimises Pores: By regulating sebum production, it prevents pores from getting clogged and reduces the stretched, enlarged appearance of pores over time. 

Fades Dark Spots and Hyperpigmentation: It helps inhibit the transfer of pigment to skin cells, making it effective at fading sunspots, age spots, and post-inflammatory acne marks. 

Strengthens the Skin Barrier: It stimulates ceramide production, which boosts hydration and protects your skin from environmental damage and moisture loss. 

Reduces Redness: It has natural soothing properties that calm inflammation, making it highly beneficial for sensitive skin or for use alongside harsher active ingredients.


(How They Work Together)

Niacinamide and finger lime (a natural source of AHA and Vitamin C) work together as a harmonising, ultimate anti-aging skincare duo. They pair gentle exfoliation with barrier repair to brighten and smooth the skin. Working synergistically together to reduce wrinkles by combining gentle cellular resurfacing with deep structural support. This powerful pairing addresses both the surface texture of the skin and the underlying loss of elasticity.

Collagen Synthesis and Protection: Lime caviar is rich in Vitamin C, a vital building block for the body's natural collagen production. Niacinamide also promotes collagen synthesis by stimulating the skin's fibroblasts. Together, they help fortify the skin's structural layer, plumping wrinkles from within.

Exfoliate and Restore: Finger lime contains natural Alpha Hydroxy Acids (AHAs) that gently dissolve dead skin cells and boost cellular turnover. Niacinamide steps in to strengthen the skin barrier, minimise redness, and lock in moisture. 

Brighten and Even Skin Tone: Wrinkles are frequently accompanied by age spots and hyperpigmentation. Finger lime is rich in Vitamin C and antioxidants that help fade dark spots and hyperpigmentation. Niacinamide regulates melanin transfer, giving you a brighter, even, and more youthful-looking complexion, making them highly complementary.

Antioxidant Protection: Both ingredients protect the skin from free radicals. Finger lime promotes cellular repair, while niacinamide defends against environmental stress. They are both powerful antioxidants, together and they effectively prevent the future breakdown of existing collagen.

More on Lime Caviar

Cellular Skincare versus Regular Skincare


Cellular Skincare: How does it differ and what sets it apart from regular skincare?


Regular skincare products typically work on the surface of the skin, providing hydration and protection. Through the use of basic skincare products like cleansers, exfoliants moisturisers, and sunscreens.

These products are designed to provide surface-level benefits such as hydration, protection, and exfoliation.

While these products are essential for maintaining healthy skin, they may not always address specific concerns at a cellular level.


Cellular skincare on the other hand, is a specialised type of skincare that focuses on targeting the deeper layers of the skin, specifically the cells.

These products are formulated to target the skin at a cellular level, delivering key ingredients that can help improve skin health and appearance.

This means that the products are formulated to penetrate deeper into the skin to work on a cellular level. These products often contain ingredients that can communicate with skin cells to promote regeneration, repair damage, and improve overall skin health.

It is designed to target issues such as collagen production and synthesis from (Polyphenols and Tryptophans found abundant in our Lime Caviar Serum, moisturiser and eye serum), cell turnover and cell renewal from (AHA's abundantly found in our Lime Caviar Serum, moisturiser and eye serum) and DNA repair from (Glycyrrhetinic Acid a licorice root extract derivative, which is abundant in our Lime Caviar Moisturiser).

Key Differences Between Cellular Skincare and Regular Skincare

One of the main differences between cellular skincare and regular skincare is the depth at which they work.

Cellular skincare targets the skin at a deeper level, addressing specific skin concerns from the inside out, also by reducing inflammation, and protecting against environmental damage at a cellular level.

Regular skincare, on the other hand, focuses on maintaining the skin's surface health and appearance.

Another key difference is the types of ingredients used in each type of skincare.

Cellular skincare products often contain more potent and targeted ingredients that can deliver visible results over time. Regular skincare products, while effective for daily maintenance, do not have the same level of active ingredients.

Benefits of Cellular Skincare

One of the key benefits of cellular skincare is its ability to provide long-lasting results.

By targeting the root causes of skin aging and health, cellular skincare products can help improve the skin's appearance from within. Additionally, these products can help enhance the efficacy of other skincare products in your routine, by maximising their benefits.

However our Lime Caviar Serum, Moisturiser and eye serum work wonders and are potent enough on their own without the need for extra skincare products.

Developed by us especially to simplify your skincare routine.

The Science Behind Cellular Skincare

Cellular skincare targets the skin's living cells to improve their function. Rather than just treating the surface, these products use active ingredients and biomimetic technologies to communicate with cells. This stimulates collagen production, accelerates natural regeneration, and protects against environmental damage.


Fibroblast Stimulation: Fibroblasts are the primary cells in your dermis responsible for producing collagen and elastin. As you age, their activity naturally slows down. Cellular ingredients "wake up" these dormant cells to resume structural protein production.


Cell Signalling: Skin cells communicate constantly through signaling pathways. Certain ingredients act as natural growth factors or messengers, binding to receptors on the cell surface to instruct cells to divide, repair, or produce more collagen.


Cellular Turnover: The skin’s natural renewal cycle—where dead cells are shed and replaced by fresh ones—slows down with time. Cellular products encourage faster turnover, reducing dullness and uneven texture.


Slowing Senescence: Aging cells eventually stop multiplying but remain in the skin. These "devitalized" cells can release signals that impair surrounding cells. Advanced cellular research focuses on botanical or lab-made extracts that mitigate the negative effects of senescent cells to prolong youthful cellular metabolism


Cellular skincare products often contain certain ingredients that can help stimulate cell regeneration and repair.

These ingredients work together to support the skin's natural processes and promote a more youthful complexion.

Studies have shown that cellular skincare can help improve skin texture, reduce fine lines and wrinkles, and enhance overall skin health.
