The Ordinary Matrixyl 10% + HA and Argireline After 45: Do They Work, and How Do They Compare?
Quick summary
The Ordinary Matrixyl 10% + HA is a peptide serum, about $18 for 30ml in Australia, aimed at fine lines and firmer-looking skin. Argireline Solution 10% is its sister serum, about the same price, aimed at expression lines. Both may soften the look of fine lines over a few months. Neither lifts sagging skin.
The research on peptides is promising but small, and most of it did not test these exact serums. After 45, a peptide serum works best as one step, alongside a good moisturiser and daily sunscreen.
At Genova Skincare we make a peptide firming cream, so our product is in this comparison and we have tried to keep it fair. Results vary from person to person.

Does The Ordinary Matrixyl 10% + HA work for women over 45?
At Genova Skincare, peptide serums are one of the most common things women over 45 ask us about. Australian searches for The Ordinary Matrixyl have more than doubled in the past year, and Argireline remains a steady favourite.
The honest answer: it may help, modestly. Peptides are short chains of amino acids that act as signals in the skin. In small studies, some peptides have softened the look of fine lines over two to three months. They are gentler than retinoids, which is why many women with drier, more sensitive menopausal skin try them.
What a peptide serum will not do is lift a jawline or tighten a neck. The American Academy of Dermatology notes that creams cannot lift sagging skin, which comes from changes in fat, muscle and bone as well as skin.
What is in The Ordinary Matrixyl and Argireline, and what it means after 45
Matrixyl 10% + HA contains three peptides from the Matrixyl family: palmitoyl tripeptide-1, palmitoyl tetrapeptide-7 and palmitoyl tripeptide-38. It also has glycerin and hyaluronic acid for hydration. The brand describes the 10% as the combined Matrixyl ingredients. It is fragrance-free and alcohol-free.
Argireline Solution 10% contains acetyl hexapeptide-8, a peptide aimed at expression lines such as frown lines and crow's feet.
Here is what the research shows, in plain terms:
- Matrixyl: a 12-week trial of 93 women by Robinson and colleagues in the International Journal of Cosmetic Science found a related peptide, palmitoyl pentapeptide-4, softened fine lines. That peptide is not the one in this serum.
- Argireline: a four-week, placebo-controlled trial of 60 people by Wang and colleagues in the American Journal of Clinical Dermatology found it reduced the look of wrinkles around the eyes.
- Peptides overall: a review by Gorouhi and Maibach in the International Journal of Cosmetic Science called peptides promising but noted that many studies are small or supplier-run.
Menopause adds context. Research in Maturitas by Affinito and colleagues linked falling skin collagen to years since menopause. That is why skin can feel thinner and less springy in your 50s, and why expectations should stay realistic. Our guide to whether peptides really work on mature skin goes deeper.
The Ordinary Matrixyl vs Argireline vs Genova Firming Cream after 45
Prices were checked on 26 September 2026 and change often.
| Option | Format | Australian price | Roughly per ml | Best for |
|---|---|---|---|---|
| The Ordinary Matrixyl 10% + HA | Serum, 30ml | About $18 | About $0.60 | Fine lines, hydration |
| The Ordinary Argireline Solution 10% | Serum, 30ml | About $18 | About $0.60 | Expression lines |
| The Ordinary Multi-Peptide + HA Serum | Serum, 30ml | About $24–$27 | About $0.80–$0.90 | Several peptides in one step |
| Genova Firming Cream | Cream, 120ml pump | $69.95 | About $0.58 | Face, neck and body in one step |
| Prescription retinoid | Cream, via your GP | Varies | Varies | Strongest evidence for lines |
Per millilitre, the prices are close. The real difference is format. The Ordinary's serums are a single step that most people follow with a moisturiser.
Genova Firming Cream is a cream with hexapeptide-10, squalane and shea butter, so it moisturises as well, and the 120ml pump covers face, neck and body. Its key actives are supplier-developed, and we do not quote supplier test figures, because they are not independent studies. It also contains fragrance, which The Ordinary's serums do not.
Pros and cons of The Ordinary Matrixyl and Argireline after 45
Pros:
- Affordable and easy to find
- Gentler than retinoids for most skin
- Fragrance-free and alcohol-free
- Some peptide research behind them, including a placebo-controlled Argireline trial
Cons:
- Neither serum has been independently trialled as a finished product
- Small, subtle effects that take months
- The brand advises against using them with acids or vitamin C in the same routine
- Still need a moisturiser on top for dry menopausal skin
Limitations: what no peptide product can do
No peptide serum or cream lifts sagging skin, jowls or a loose neck, or replaces a procedure. Genova Firming Cream is a cosmetic designed to help skin look and feel firmer and smoother. It does not change skin structure.
If lines are your main concern and your skin tolerates it, a retinoid has stronger evidence. Your GP can talk you through the options.
Is a peptide serum or a firming cream better for skin after 45?
It depends on what you want from one step. If you like layering and your skin is oily or combination, a cheap peptide serum under your usual moisturiser is a sensible start. If your skin is dry and you want one product for face and neck, a peptide cream is simpler.
If you are unsure whether you are dealing with crepey texture or true sagging, our guide to crepey vs sagging skin after 45 helps you tell. For more cream options at every price, see our face and neck firming cream buyer's guide.
Who these products suit after 45, and who they do not
They may suit you if you have fine lines, want something gentler than retinol, or found retinol too irritating. Our comparison of peptides vs retinol for menopausal skin explains the trade-off.
They are not for you if you are hoping for a lift, your main concern is deep folds, or your skin reacts to fragrance (in the case of Genova Firming Cream). Patch test any new product first.
How to use peptides after 45: step by step
- Patch test. Try a small area for a few days.
- Cleanse gently. Pat skin almost dry.
- Apply a peptide serum morning or night. A few drops is enough.
- Keep acids and vitamin C for another time of day. The Ordinary advises against layering them together.
- Moisturise, or use a peptide cream instead. Genova Firming Cream is applied once daily at night, taken down the neck.
- Wear SPF 50+ every morning. Sun damage undoes any progress.
- Judge at 8–12 weeks. Compare photos in the same daylight.
Realistic expectations
Hydration and softness show within days. Any softening of fine lines takes 8–12 weeks of daily use.
Changes are subtle and vary from person to person. Results vary.
The Ordinary Matrixyl and Argireline questions Australian women over 45 ask
Which is better, Argireline or Matrixyl?
Argireline is aimed at expression lines, while Matrixyl is aimed at general fine lines and firmness. Many people use both at different times of day.
Is Matrixyl more effective than retinol?
No. Retinoids have much stronger evidence for lines. Peptides are a gentler option for skin that cannot tolerate retinol.
Can I use Matrixyl every day?
Yes, the brand suggests morning and evening. It is generally well tolerated.
What should you not mix with Matrixyl?
The Ordinary advises against using it in the same routine as direct acids, vitamin C or salicylic acid. Use those at another time of day.
Can peptides tighten a sagging neck?
No. They may help neck skin look smoother, but they cannot lift loose skin.
The Ordinary after 45: our honest series
The Ordinary's peptide serums are an affordable, gentle way to try peptides, and many women over 45 like them. If you would rather one pump bottle for face and neck that also moisturises, ours is built for that. Either way, be kind to your skin and give it time.
