DEMYSTIFYING: PEPTIDES

By Flo Bellinger, 23 March 2026

If you’re into skincare, you’ll know there’s always a new ingredient on the block. Hyaluronic acid, retinol and vitamin C have all had their moment in the sun. And that’s not to say these aren’t great additions to your routine. But the word on everyone’s lips lately has been peptides. These little powerhouses are boosting our lotions and potions with anti-ageing potency and brightening properties. And yet, like many beauty innovations, they’ve become a bit of buzzword. So what do peptides actually do? And how should you use them for the best results? Keep scrolling for an in-depth breakdown of everything there is to know about peptides, and the products we’d recommend investing in.

WHAT ARE PEPTIDES?

In simple terms, peptides are small versions of proteins. These short strings of amino acids – typically comprising 2 to 50 amino acids – are the building blocks of protein. But thanks to their small size, they’re easier for the body to break down and they can quickly penetrate the skin to access the bloodstream. This makes peptides an efficient vehicle for popular ingredients like collagen and creatine, which provide a range of potential benefits for the skin.

HOW DO PEPTIDES AFFECT YOUR SKIN?

The most popular peptides in the skincare world are collagen peptides, which may benefit skin health and slow the effects of ageing. As we get older, our body produces less collagen, leading to loss of elasticity in the skin. Peptides can help the body to produce collagen more efficiently, which in turn can calm inflammation, strengthen the skin barrier, and fight signs of ageing. Another reason peptides are so popular is that they’re relatively gentle. This makes them a great option for those with sensitive skin, providing a less aggressive alternative to other popular anti-ageing products like retinol.

Now you’ve got a grasp on peptides themselves, how do you integrate them into your skincare routine? Like everything in the beauty world, price points can range considerably – and if you’re new to the peptide game, it’s worth starting small. The Ordinary has a great multi-peptide serum with added hyaluronic acid, combining the anti-ageing qualities of peptides with a boost of hydration. This water-like serum can be applied morning and night to clean skin, before the rest of your skincare. Gentle, no-frills and easy to use – this is a contender of the best all-round peptide product on the market. And given it’s less than £16, you really can’t go wrong.
