While we can all agree ageing is a privilege, there are some mornings where we want our skin to look just that little bit more plump and bouncy.
Enter a peptide serum.
The latest craze in the beauty world by storm, peptides are short chains of amino acids that are commonly used to support the function of your skin barrier and increase overall hydration.
“Think of them as the building blocks of proteins like collagen and elastin, which are essential for firm, youthful-looking skin,” says Daniel Isaacs, Chief Product Officer at Medik8.
Even Hailey Bieber is a fan.
“I really, really love peptides for the skin, I think that it’s one of the best ingredients to use”, she told Glamour.
So much so, that she created the TikTok-viral Rhode Skin Peptide Glazing Fluid.
While we can’t get our hands on it in Australia just yet, here are some more peptide serums you can use to help get Hailey’s incredible skin – including one that delivers “instant results” for plump and bouncy skin.
OUR TOP PICKS
EDITOR’S PICKS: BEST PEPTIDE SERUMS
Medik8 Liquid Peptides Advanced MP, $160 at Adore Beauty
Why we love it: Offers a clinically proven formula that feels lightweight and gentle on the skin.
What to consider: High price tag.
Formulation: Serum | Size: 30ml | Best for: All skin types, especially those with mature skin
Tried and Tested by Stephanie Yip, eCommerce Travel Writer
As I boldly head into my 40s, wrinkles, fine lines and expression lines have begun to creep across my face at what feels like lightning speed. Yup, once you’ve seen them, it’s hard to unsee them. So in an attempt to slow things down, I’ve upped my beauty routine to include Medik8’s new Liquid Peptides Advanced MP.
Packed with Dual Mini Proteins, this pocket rocket aims to gently relax and smooth lines within minutes, and plump up skin by boosting its collagen, elastin and hyaluronic acid levels over a few weeks.
Obviously the sceptic in me took this with a grain of salt, but truly the effects were almost instantaneous and, after three weeks, my eye wrinkles have flattened out and my self confidence is through the roof.
On top of the results, I love how light and fast absorbing the serum is and that it’s scent free, so it works well with the rest of my skincare routine.
I’m now actively using it to target a pesky frown line that’s been bothering me for years and I’m confident that it’ll be hardly noticeable in a few weeks.

I’ve gone through a few bottles of this stuff and let me tell you, it is liquid gold. The Pro Collagen Multi Peptide Booster from Paula’s Choice is one of the most hydrating, soothing and repairing serums I’ve ever tried. Formulated with a bunch of – you guessed it – peptides, this lightweight and silky serum works almost instantly and absorbs quickly.

WHAT TO LOOK FOR WHEN BUYING A PEPTIDE SERUM
When choosing peptide serums to include in our list, we evaluated several factors:
Budget: You don’t need to break the bank to find a potent peptide serum. We’ve got picks on our list for as little as $16.
Skin type: Your skin type can influence the kind of peptide serum you choose to buy. If you have oily skin, avoid anything filled with heavy oils. And if you have dry skin, looking for hydrating ingredients like hyaluronic acid and glycerin.
Added ingredients: While a peptide serum works great on its own, you can look for a serum with added ingredients to reap even more benefits.
HOW WE CHOOSE PRODUCTS
With hundreds of serums available, it’s impossible to test every product out there. In our search for the best peptide serums, we read hundreds of customer reviews and looked at test results and ratings from product review sites to find the best one for you.
We also spoke to Daniel Isaacs, Chief Product Officer and Founding Partner of Medik8, to figure out why our skincare routine could benefit from adding a peptide serum.
FREQUENTLY ASKED QUESTIONS
DO PEPTIDE SERUMS ACTUALLY WORK?
Yes – like anything, if you use them consistently in your skincare routine, you’ll see great results.
Daniel explains, “peptides have always been a cornerstone of this approach due to their ability to deliver transformative results while working harmoniously with the skin. They are an essential ingredient for maintaining youthful, radiant skin.”
HOW LONG DOES IT TAKE TO SEE RESULTS FROM USING A PEPTIDE SERUM?
“Consistency is key with all skincare but some peptide products can help your skin start to show results with their key benefits within weeks, but long-lasting visible results will take 6-12 weeks,” Daniel shares.
WHAT MAKES MEDIK8’S LIQUID PEPTIDES ADVANCED MP DIFFERENT TO OTHER PEPTIDE SERUMS ON THE MARKET?
It all comes down to the formula, and that’s why the Liquid Peptides Advanced MP is our top pick for peptide serums.
“Our breakthrough Dual MiniProteins are highly powerful like a peptide and potent like a protein. But the key is their shrunken size, which enables them to best penetrate the skin.”
More Coverage
He continues, “think of them as small, but mighty in their ability to target cells that need them most to smooth and firm the skin for rapid wrinkle reduction.”
