You don't need to spend a lot to try a peptide serum. Some of the best-known options in Australia cost less than a takeaway lunch, and they name their peptides clearly on the label. Here's how the budget picks stack up.
Our picks at a glance
- Cheapest per ml: The Ordinary Argireline Solution 10%.
- Best for beginners, and firmness on a budget: The Ordinary Matrixyl 10% + HA.
- Best for hydration: The Ordinary Multi-Peptide + HA Serum.
All three are 30ml serums, and every one of them comes in under $50 at the prices we saw.

Cheapest per ml
The Ordinary Argireline Solution 10% is the lowest price per ml on our list. It's a simple, watery serum built around one peptide: acetyl hexapeptide-8, better known as Argireline. Brands market it for the look of expression lines, like those around the eyes and on the forehead.
It's a single-job serum, so it's easy to slot into a routine you already have. Apply it before heavier creams.

Best for beginners
The Ordinary Matrixyl 10% + HA is a gentle first step. It pairs two Matrixyl peptides (Matrixyl 3000 and Matrixyl synthe'6, 10% in total) with hyaluronic acid in a light serum. Matrixyl is one of the best-studied cosmetic peptides, and brands market it for skin that looks firmer and smoother.
If you're new to peptides and want something low-fuss, this is a good place to start. It's also the pick if firmness is your main goal on a budget.

Best for hydration
The Ordinary Multi-Peptide + HA Serum (once called "Buffet") combines several peptides, including Argireline and Matrixyl peptides, with hyaluronic acid for hydration. It's a good all-rounder if your skin feels tight or dry and you want one serum that does a bit of everything.

How we chose
We started with peptide serums that are easy to buy in Australia and cost $50 or less. Then we looked at four things:
- What's in the bottle. Each pick names its peptides clearly on the label. Where the brand states a percentage, we show it. Where it doesn't, we write "% not stated".
- Size and price per ml. We compare the price per ml, so a small cheap bottle and a large one can be compared fairly.
- Ratings with a source. We show third-party ratings with where they came from. We don't make up our own star ratings.
- Where to buy. Each serum links to an Australian retailer.
We don't take payment to include a product. Some links on this page are affiliate links, which means we may earn a small commission at no extra cost to you. It never changes the order, which is always by price per ml.
Peptide serums are cosmetic products. Results vary from person to person, and a cheaper serum used consistently is often a better bet than a pricey one you forget to use. Patch test anything new, and talk to a dermatologist or your GP about any skin concern.
The short version
- You can try a well-labelled peptide serum for well under $50.
- Cheapest per ml: The Ordinary Argireline Solution 10%.
- Gentle start, and firmness on a budget: The Ordinary Matrixyl 10% + HA.
- Hydration all-rounder: The Ordinary Multi-Peptide + HA Serum.
