When it comes to skincare, there are a lot of ingredients that make lofty claims about what they can do for your complexion. But, despite some controversy, peptides are one of the few scientifically and dermatologically proven ingredients to truly make a difference in combating fine lines and wrinkles, sagging skin, fading dark spots and improving hydration.
Essentially, they are fragments of proteins and they signal cells to do certain things – the exact action depends on which amino acid is linked to it. As a result, the results are varied. Some are anti-inflammatory, others hydrate, some promote collagen production or inhibit elastin break down. “Peptides can also help improve the appearance of fine lines, dark circles, crow’s feet and crepey skin,” says Dr Ewoma Ukeleghe, medical and cosmetic doctor at Skndoctor.
The best peptides uk will include those derived from collagen, but there are other forms to consider too. For instance, structural peptides are unique in that they work to improve the skin barrier function, which can make a big difference when it comes to dryness and dehydration. These tend to be keratin peptides (derived from the protein that makes hair and nails), but there are some peptides sourced from wool that mimic squalene, a natural lubricant found in the skin that’s great for hydrating.
Other peptides are more specialised, aiming to plump the skin and tackle aging around the eye. Unlike Retinol, which can be irritating to the delicate eye area, peptides offer a gentler approach, which can smooth out and soften lines and wrinkles, reduce puffiness and brighten the under-eye complexion. You’ll often find these in eye serums and creams, but they can be found in face creams too.
When selecting a peptide product it’s important to look at the overall ingredients list, as well as looking at what other people have said in terms of reviews. The best peptides will come from brands that conduct their own testing – for example, Core Peptides offers a wide range of peptide options including the unique GnRh which has very specific effects on the skin. They offer a variety of payment methods and have a 5% discount that can be stacked with the 10% off code below to give you 15% off, making them an extremely cost-effective option for top-quality peptides.
