Hyaluronic Acid vs Collagen Australia 2026: Skin Verdict

Last updated: September 26, 2026 · Originally published: June 13, 2026 · By Eternal Elixir Editorial

Hyaluronic acid and collagen do different jobs in the skin. Hyaluronic acid holds water, and collagen is the protein framework that keeps skin firm. As supplements, oral hyaluronic acid has the more consistent recent evidence for hydration: a 150-person trial found 120 mg a day for 12 weeks improved skin hydration and elasticity against placebo. Collagen looks good in pooled trials overall, but a 2025 review of 23 trials found no benefit once it looked only at high-quality or non-industry-funded studies. Taking the two together is common and there’s no known reason not to, though only one combined-product trial has been published that we could find.

Below we set out the difference between hyaluronic acid and collagen, what each has shown in human trials, what the combined collagen and hyaluronic acid supplements at Chemist Warehouse contain compared with the trial doses, and what we sell for skin.

Eternal Elixir makes Reduced L-Glutathione 2000mg and Grass-Fed Tallow Balm. Neither is hyaluronic acid or collagen, so read them as an alternative from our range, not a like-for-like swap. We cover the evidence for each further down.

Hyaluronic Acid vs Collagen: What’s the Difference?

Hyaluronic acid (HA) is a long sugar chain, a glycosaminoglycan, that sits between skin cells and binds water. Collagen is a fibrous protein, mostly types I and III in skin, that gives the dermis its strength. Both are made by the body. Supplements supply them from outside: HA can be made by fermentation, while collagen always comes from animal sources such as fish, cattle, pigs or chicken.

When you swallow either, it is broken down in the gut. Neither lands in your skin unchanged. The question the trials try to answer is whether the fragments or peptides that get absorbed change how skin measures on instruments: hydration, elasticity, wrinkle depth and water loss.

For a wider view of skin ingredients, see our guide to the best skin supplements in Australia.

How Hyaluronic Acid Works for Skin

The largest single trial is recent. It randomised 150 healthy adults to 60 mg or 120 mg of sodium hyaluronate a day, or placebo, for 12 weeks (Dolečková et al., 2025). At 120 mg, skin hydration and elasticity went up, water loss through the skin fell, and wrinkle depth around the eyes decreased compared with placebo. The 60 mg dose showed similar but smaller effects. Skin colour, redness, pore size and gloss did not change.

A shorter trial gave 60 women with mild to moderate signs of skin ageing 200 mg a day of a full-spectrum HA, a blend of molecular weights, or placebo for 28 days (Michelotti et al., 2021). Hydration rose by 10.6%, wrinkle depth fell by 18.8% and elasticity rose by 5.1%.

A 2025 meta-analysis pooled 7 randomised trials of oral HA and found significant improvements in hydration, elasticity and wrinkle depth (Amin et al., 2025). Firmness, wrinkle volume and water loss moved in the right direction but did not reach significance. The authors flag the small total sample and the differences between trials, and ask for larger ones.

What this means in practice: expect changes you can measure over one to three months, mainly in hydration. The trial products differ in molecular weight, so a result for one HA does not automatically transfer to another. Our evidence review on whether hyaluronic acid tablets work goes through more of the trials, and our guide to hyaluronic acid supplements in Australia covers forms and doses.

How Collagen Works for Skin

Collagen supplements are hydrolysed, broken into small peptides so they can be absorbed. The best-known trials used specific collagen peptides. In one, 69 women aged 35 to 55 took 2.5 g or 5.0 g a day, or placebo, for 8 weeks. Skin elasticity improved in both collagen groups, while changes in moisture did not reach significance (Proksch et al., 2014). In another, 114 women aged 45 to 65 took 2.5 g a day for 8 weeks, and eye wrinkle volume fell by 20% compared with placebo (Proksch et al., 2014).

Pooled results depend on which trials you count. A 2021 meta-analysis of 19 trials with 1,125 participants, 95% of them women, found better hydration, elasticity and wrinkles on collagen than on placebo (de Miranda et al., 2021). A 2025 meta-analysis of 23 trials with 1,474 participants found the same overall, then split the trials by funding and quality (Myung and Park, 2025). Trials without pharmaceutical-company funding showed no effect on hydration, elasticity or wrinkles, and neither did the high-quality trials. The authors concluded there is currently no clinical evidence that collagen supplements help with skin ageing.

That is the strongest case against collagen, and it is a serious one. The case for it is the number of positive trials and the consistency of the elasticity results. If you try collagen, pick a product that matches the trial doses, give it 8 to 12 weeks, and judge it on what you see. Our roundup of the best collagen supplements in Australia compares products and doses.

Is It Good to Take Collagen and Hyaluronic Acid Together?

There’s no known interaction between the two, and many products combine them. The trial evidence for the combination is thin. The one randomised trial we found gave 128 women aged 39 to 59 a chicken sternal cartilage extract twice a day for 12 weeks (Schwartz et al., 2019). Each 500 mg dose held at least 300 mg of hydrolysed type II collagen, 100 mg of chondroitin and 50 mg of hyaluronic acid. Among the 113 women who finished, facial lines and wrinkles fell and elasticity and skin collagen content rose compared with placebo, but skin-surface water content did not differ. The supplement was well tolerated.

The combined products on Australian shelves use different ingredients from that trial, so its result doesn’t carry across directly. Here is what two of them contain, as listed on their product pages in Sep 2026:

• Swisse Beauty Collagen + Hyaluronic Acid Booster: 4 tablets a day give 2,500 mg of hydrolysed collagen, 133.32 mg of sodium hyaluronate, 200 mg of vitamin C and 10 mg of zinc. It costs A$44.99 for 80 tablets, which is 20 days, or about A$2.25 a day.
• Nature’s Way Beauty Collagen + Hyaluronic Acid: 3 tablets a day give about 2,500 mg of hydrolysed collagen and 150 mg of sodium hyaluronate. At Chemist Warehouse it was A$19.99 (RRP A$39.99) for 60 tablets, 20 days, or about A$1.00 a day.

Both hit the lower end of the collagen trial range (2.5 g) and sit inside the HA trial range (60 to 200 mg). Both labels say use must be limited to 3 months and that the product is not recommended in pregnancy or breastfeeding.

Hyaluronic Acid vs Collagen: Which Should You Choose?

Choose on the problem you want to change and on how much weight you give the evidence.

For dry, tight or dull skin

Hyaluronic acid is the closer match. Its trials measured hydration and water loss directly, and the largest recent trial found a benefit at 120 mg a day. A good topical moisturiser also works on dryness from the outside, at the surface where you feel it.

For firmness and elasticity

Collagen is the ingredient aimed at this, and its elasticity results are the most consistent part of its record. Go in knowing the independent, high-quality trials didn’t find a benefit.

For both

A combined product covers both at trial-level doses if you choose carefully. Check the collagen amount per daily serve, not per tablet, because most products need 3 or 4 tablets a day to reach 2.5 g.

Choosing a Hyaluronic Acid or Collagen Supplement in Australia

Four checks save money and disappointment:

• Dose per daily serve against the trials. Around 120 to 200 mg for HA, and 2.5 g or more for collagen peptides. Very low-dose drinks and gummies often fall short.
• Cost per day, not per bottle. Divide the price by the number of days a pack lasts at the full daily serve.
• Label limits. Many combined products in Australia carry a 3-month limit and a warning for pregnancy and breastfeeding.
• Time. The trials ran 4 to 12 weeks. Judge a product after that, not after a fortnight.

What Eternal Elixir Sells for Skin

We don’t sell collagen, and our Hyaluronic Acid 200mg capsules are sold out. We are not going to pretend another product does the same job. These are the two skin products we have in stock, and what the evidence behind each looks like.

Reduced L-Glutathione 2000mg (oral)

Glutathione is an antioxidant the body makes itself. In the main skin trial, 60 healthy women aged 20 to 50 in Bangkok took 250 mg a day of reduced glutathione, 250 mg a day of oxidised glutathione, or placebo for 12 weeks (Weschawalit et al., 2017). The reduced-glutathione group had fewer wrinkles than placebo at some of the measured sites, and elasticity tended to improve. It was well tolerated. A separate six-month trial in 54 adults found that 250 mg or 1,000 mg a day raised glutathione levels in blood cells (Richie et al., 2015).

Our serve is two capsules, 2,000 mg a day. That is eight times the 250 mg used in the skin trial and double the highest dose Richie tested. A 90-capsule bottle is 45 serves at A$39.99, or A$0.89 a serve. The skin evidence for glutathione is smaller than for HA, so treat it as an option from our range for skin from the inside rather than a stand-in for HA.

Grass-Fed Tallow Balm (topical)

If dryness is the reason you were looking at HA, a balm works on the skin surface directly. Ours is grass-fed beef tallow, organic raw beeswax, organic virgin coconut oil, organic raw honey and vitamin E, applied to clean skin as needed. The research on tallow itself is limited: a 2024 scoping review found 19 relevant studies and called for more human trials (Russell et al., 2024). It is a moisturiser, not a supplement.

If you are building a wider routine, Trans-Resveratrol 1200mg is another antioxidant in our range, and our guide to the best supplements for women over 40 covers more options. You can also browse the full range.

Frequently Asked Questions

Is hyaluronic acid or collagen better for skin?

They target different things. Hyaluronic acid is aimed at hydration, and its recent trials, including a 150-person trial at 120 mg a day, found improvements in hydration and elasticity. Collagen is aimed at firmness, and while many trials are positive, a 2025 review found no benefit in the independent and high-quality trials. On current evidence, HA has the steadier record.

Can you take hyaluronic acid and collagen together?

Yes. There’s no known interaction, and many products combine them. Only one randomised trial of a combined supplement turned up in our search, and it found fewer facial lines and better elasticity over 12 weeks. Check that the combined product reaches trial doses per daily serve.

How long does hyaluronic acid take to work on skin?

The trials measured changes from 28 days to 12 weeks. A 200 mg a day trial found better hydration after 28 days, and a 120 mg a day trial found improvements over 12 weeks.

Does oral hyaluronic acid actually work, or only topical?

Oral HA has shown measurable effects in randomised trials, and a 2025 pooled analysis of 7 trials found better hydration, elasticity and wrinkle depth. The authors called for larger trials. Topical HA works at the surface, and using both is reasonable.

Can I take a collagen supplement with citalopram?

We found no published study on collagen with citalopram. Combined products often add vitamins, zinc and other ingredients, so ask your pharmacist to check the full label against your medicines before you start.

Does Eternal Elixir sell collagen or hyaluronic acid?

We don’t sell collagen, and our hyaluronic acid capsules are sold out. Our in-stock skin products are Reduced L-Glutathione 2000mg, taken by mouth, and Grass-Fed Tallow Balm, applied to the skin.
