There’s been a lot of hype about peptides – and rightly so, since these amino acid strings can do wonders for your skin, muscles, and even your weight. Basically, lab-made versions of proteins that are found naturally in your body, they’re also found in skincare products and are used to enhance the effects of other ingredients such as retinol.
When applied topically, peptides stimulate collagen production and help strengthen the skin’s barrier function. They’re particularly beneficial for ageing or post-menopausal skin, as they can boost the skin’s elasticity and firm it up. They’re also often combined with other game-changing ingredients such as retinol, which helps increase skin cell turnover for brighter, more radiant skin, or antioxidants such as niacinamide to reduce redness and blemishes.
If you’re thinking about giving peptides a go, it’s best to look for a serum that combines the ingredient with other actives such as hyaluronic acid, ceramides or vitamin C for maximum effectiveness. This formula from Hailey Bieber’s buzzy new brand, Rhode, does just that – as well as improving the appearance of fine lines and wrinkles, it smooths the complexion and hydrates.
As a peptide specialist, Dr Sommerlad explains that there are four broad categories of peptides: signal, carrier, enzyme inhibitor and neurotransmitter, which all work differently on the skin. Many serums contain several different types, and the one from Youth To The People combines drone copper peptides with a super-signalling Matrixyl 3000 complex to diminish the appearance of fine lines and wrinkles while improving the skin’s hydration and brightness.
Known for its cult-loved range of cleansers, toners and moisturisers, Paula’s Choice sells change-making products that explain each ingredient on the label. This multi-peptide serum, which is formulated with niacinamide and flower ferment filtrate for brighter skin, bolsters the effects of other products by increasing their efficacy.
The Ordinary is a beauty blogger favourite, and for good reason – its serums are a great way to add peptides into your routine. Its soothing, non-sticky formula blends three peptides with hyaluronic acid and vitamin C for plumper, more resilient skin. It’s especially effective for those with sensitive skin, as it doesn’t irritate or cause breakouts.
If you want to minimise the appearance of dark circles and puffiness, try this peptide serum from Indeed Labs. The brand claims it reduces muscle contractions, which in turn stops the formation of additional wrinkles. It’s also infused with niacinamide and vitamin E for brighter, more refreshed skin. Unlike some more intensive serums, it doesn’t have any fragrances or oils so you can easily layer it under makeup for a smoother finish.best peptides uk
