Peptides
Peptides are short chains of amino acids that act as building blocks for proteins like collagen and elastin in the skin. In skincare, they are popular ingredients that help support the skin’s natural firmness and elasticity. They are gentle yet effective, making them a favourite in anti-ageing creams, serums and eye treatments.
How it works in skincare
In cosmetics and skincare, peptides function as signalling molecules that communicate with skin cells to encourage the production of collagen, elastin and other structural proteins. When applied topically they penetrate the upper layers of the skin and help to visibly improve firmness and texture while supporting the skin’s natural repair processes. Because they are relatively small molecules, many peptides are formulated to be easily absorbed without irritation, making them suitable for daily use in a wide range of moisturisers, serums and masks.

Where it comes from
Peptides used in cosmetics are typically produced in laboratories through the controlled breakdown of plant or animal proteins, or synthesised from individual amino acids. Common sources include rice, soy, wheat and collagen derived from sustainable marine or bovine origins.
