Peptides

Peptides are a more recent addition to the skincare armamentarium, as if we needed any more products to choose from! So what exactly are they, and what is it they’re claimed to do? 

What are peptides? 

Peptides are short chains of amino acids. Amino acids make up proteins such as collagen and elastin, which are important for skin health. 

What do peptides do? 

There’s some evidence that applying peptides to the skin may stimulate collagen production, reduce the appearance of wrinkles and have anti-ageing benefits. However, the evidence behind peptides isn’t as robust as it is for some other ingredients. 

Should I be using peptides in my skincare routine?

Given that there isn’t as much evidence supporting the use of peptides, it may be best to start off with the things we know for sure work, such as retinoids, niacinamide, vitamin C and alpha and beta hydroxy acids. However, if you’re already using these and want to add something else into your regime, by all means add peptides.
