Phyaluronic® Serum is made using Australian seaweed-derived ingredients and is not tested on animals.
Our lightweight, plant-based formula is designed to hydrate mature skin without the heavy, greasy feeling of traditional creams.
Proudly made in Australia.
Developed from more than 25 years of marine research by Dr. Pia Winberg, PhD.
In laboratory testing, the marine molecule demonstrated the ability to bind over 20× its weight in water.
And in a University of Wollongong experiment, collagen combined with the seaweed material retained 6× more collagen after enzyme exposure compared with untreated collagen.
These are laboratory findings, not measured clinical outcomes from serum use.
FREE shipping on every order, whether you subscribe or purchase once.
Your order is also protected by our 90-day money-back guarantee.
Use the serum consistently for 90 nights. If your skin isn’t noticeably plumper and your dehydration lines haven’t visibly softened, simply email us for a refund.
No bottles to return.
Just two drops, once a day.
Apply to clean, slightly damp skin across your face, neck, and hands. Gently spread the serum and allow it to absorb.
Follow with your usual moisturiser to help seal in hydration.
Lightweight, fast-absorbing, and easy to add to your existing skincare routine.
Your 90-Day Skin Timeline
From Dry, Crepey Skin to a Smoother, Plumper-Looking Complexion
-
Day1
A Fresh Dose of Hydration
Just a few drops deliver lightweight hydration without the greasy, heavy feeling of traditional creams. Your skin feels soft, fresh and comfortable.
-
Day2–7
Less Dryness, More Comfort
As your skin holds onto more moisture, that familiar tight, parched feeling can begin to fade. Skin feels softer and more comfortable throughout the day.
-
Weeks3+
Fine Lines Begin to Soften
With consistent hydration, fine dehydration lines can appear smoother, crepey areas feel more supple, and dull skin takes on a fresher, plumper appearance.
-
Day90
See the Difference or Your Money Back
Give your skin 90 days of consistent care. If it isn’t noticeably plumper and your dehydration lines haven’t visibly softened, we’ll refund every dollar.
Five reasons
Why Phyaluronic® Serum Is Different From Everything You’ve Tried
-
01
It Helps Plump the Lines That Age Leaves Behind.
As mature skin loses its natural water-gel, fine lines become more visible. Phyaluronic® helps retain moisture for smoother, plumper-looking skin.
-
02
Extraordinary Hydration, Backed by Science.
Our Australian seaweed molecule demonstrated exceptional water-binding capacity in laboratory testing, holding over 20 times its dry weight in water.
-
03
10.1× Skin Cell Growth
In laboratory research, skin cells grown on a 3D-printed Ulva seaweed scaffold increased 10.1× from day 1 to day 14. Since healthy skin relies on cell growth and renewal, this highlights the potential of seaweed-based materials to support living skin tissue.
-
04
6× More Collagen Preserved
In University of Wollongong testing, 36% of collagen remained with the marine molecule, compared with just 6% without it. Since collagen provides the structure that keeps skin firm, this suggests the molecule’s potential to help protect that framework.
-
05
50% Phyaluronic®. Our Highest Concentration.
Unlike formulas with only a small amount of their main active, our serum is built around 50% Phyaluronic®.
Zero stinging or peeling

Meet the scientist behind Phyaluronic®
25 Years of Research. One Very Personal Discovery.
Dr. Pia Winberg, PhD, is an ABC Top 100 Scientist who has spent over 25 years researching Australian seaweed and its potential for human skin.
In 2019, a devastating laboratory accident left her needing six reconstructive surgeries. During her recovery, she used formulations from her seaweed research alongside medical treatment.
That experience strengthened her mission to bring marine science into everyday skincare, eventually leading to Phyaluronic®.

Matched Against The Research
Based on Your Skin Profile, Here’s Why What You’ve Tried Hasn’t Worked
As estrogen declines, your skin can lose some of the natural molecules that hold water within it. That’s why even expensive skincare can leave you dealing with the same dryness, crepey texture and visible lines.
The claim: A richer, thicker cream will keep your ageing skin hydrated and smooth.
The truth: Moisturisers help soften skin and protect its outer barrier. But menopause can also reduce the natural water-holding molecules within your skin. A heavier layer of cream doesn’t necessarily make up for that loss of internal moisture.
That’s why you can moisturise every morning and still feel tight, dry and crepey by the afternoon.
Journal of Cosmetic Dermatology, 2025.
The claim: Hyaluronic acid attracts water, plumps your skin and smooths fine lines.
The truth: It can. Clinical research confirms hyaluronic acid improves hydration and skin appearance.
But if you’ve already tried ordinary HA serums and still aren’t satisfied, Phyaluronic® offers a different approach: a patented Australian seaweed complex formulated at our highest concentration of 50%.
Dermatology and Therapy, 2021.
The claim: Accelerate skin renewal to smooth wrinkles and reverse visible ageing.
The truth: Tretinoin can improve photoaged wrinkles. But studies also document dryness, redness, peeling and stinging — especially during early treatment.
For already dry, reactive menopausal skin, that can make consistent use difficult. Phyaluronic® instead focuses on gentle, everyday hydration without relying on retinoids.
Dermatology Practical & Conceptual, 2025.
The claim: Take collagen every day to rebuild firmer, younger-looking skin.
The truth: The evidence is mixed. A 2025 analysis of 23 clinical trials found that apparent benefits disappeared when researchers focused on higher-quality or non-industry-funded studies.
And while collagen matters for skin structure, your skin also needs moisture to maintain its smooth, plump appearance.

Questions
Frequently asked
Not at all. Although menopause changes how your skin maintains moisture, that doesn’t mean it can no longer benefit from hydration.
Phyaluronic® is designed to help mature skin retain moisture, making dry, crepey areas feel softer and fine dehydration lines appear smoother.
Hyaluronic acid can hydrate skin, but Phyaluronic® is a different marine-derived complex developed through over 25 years of Australian seaweed research.
Our serum contains 50% Phyaluronic®, our highest concentration. The seaweed material has demonstrated the ability to hold over 20 times its dry weight in water in laboratory testing.
Hydration is the first thing to look for. Your skin may begin feeling softer and more comfortable in the first few days.
Over the following weeks, consistent hydration can help fine dehydration lines appear smoother and crepey areas feel more supple.
Individual results and timing vary.
The 50% refers to our marine complex, not an exfoliating acid.
Phyaluronic® Serum is lightweight and designed to support skin hydration without a heavy, greasy finish. As with any skincare product, individual reactions are possible, so patch-test first if your skin is particularly reactive.
That’s why we offer Dr. Pia’s 90-Day Money-Back Guarantee.
Use Phyaluronic® Serum consistently for 90 days. If your skin isn’t noticeably plumper and your dehydration lines haven’t visibly softened, simply email us for a refund.
Every dollar back. Keep the bottle. Nothing to return.
Rapid weight loss can make existing wrinkles and facial volume loss more noticeable, while skin may also feel drier.
Phyaluronic® helps support hydration and a plumper-looking skin surface. It won’t replace lost facial fat, but it can help improve the appearance of dryness and fine dehydration lines.
