6 Peptide Serums For Plump, Youthful-Looking Skin

The gentle alternative to potent anti-ageing ingredients.
Imaan Hammam

If you have access to the Internet, then you’ve probably been swept up in the wave that is peptide skin care.

Popularised by Hailey Bieber and her glazed skin, fans looking to emulate the star’s glossy visage clamoured to secure Rhode Skin’s Peptide Glazing Fluid when it launched in June 2022. But for those of us who live in Australia (AKA outside of Rhode’s shipping territory), we’ve been relegated to hunting our local beauty retailers and department stores for peptide serums that deliver the same plump, youthful-looking finish.

Thankfully, we didn’t have to search too hard, because there are plenty of equally impressive serums available down under that feature the gentle anti-ageing ingredient alongside a slew of supporting superstars like hyaluronic acid, niacinamide, panthenol, squalane, amino acids and the list goes on. Used on the daily, these peptide serums work to reinforce proteins in the skin like collagen and elastin to help visibly plump and firm the skin, as well as smooth visible fine lines and wrinkles.

Down to try this buzzworthy skin care ingredient? Ahead, marie claire rounds up the best peptide serums to shop in Australia.

What does a peptide serum do?

Peptides are short chains of amino acids that are the building blocks of certain proteins needed by the skin (read: collagen and elastin). Using a peptide serum can help to firm and plump skin, and smooth fine lines, for a more youthful-looking complexion.

Is peptide serum better than hyaluronic acid?

Peptides and hyaluronic acid are complementary skin care ingredients that work well together, however it’s tough to compare the two ingredients as they have different properties. Both ingredients can plump and smooth fine lines, but they don’t do this in the same way. Hyaluronic acid temporarily draws moisture into the skin to plump and hydrate, while peptides reinforce proteins in the skin.
