Introduction:

We think Rhode by Hailey Bieber played a huge role in popularising peptides. We know science-based skincare is the most effective approach to glowing, healthy skin, and peptides are currently all the rage in skincare and beauty products.

What Exactly Are Peptides? 

Peptide products are often recommended by dermatologists for their ability to heal skin, slow ageing, and stimulate collagen and elastic production, according to Vogue. This means the they can make your skin smoother, moisturised and more radiant. 

“At their most basic, peptides are short chains of amino acids that form the building blocks of proteins like collagen, elastin, and keratin. These proteins are essential for firm, youthful-looking skin.” (https://www.vogue.co.uk/article/best-peptide-skincare

Essentially, Peptides are smaller versions of proteins. Although research isn’t as extensive as we’d like, there is evidence of peptides providing pro-aging support, anti-inflammatory, or muscle-building properties. (Source: https://www.medicalnewstoday.com/articles/326701)  

So what exactly are their benefits?

Building Blocks of Skin Proteins:
Peptides are short chains of amino acids that form the foundation of proteins like collagen, elastin, and keratin, which are essential for skin structure, elasticity, and firmness. 

Signaling to Skin Cells:
Applied topically, peptides act as signaling molecules, communicating with skin cells to stimulate the production of these vital proteins, which decline with age. 

Benefits for Skin:
This stimulation results in smoother, plumper, and more youthful-looking skin, with improved texture and reduced fine lines and wrinkles.
