What Are Peptides & What Do Peptides Do?

May 8, 2021 | Skincare 101

Peptides in skincare are being hailed as new wonder ingredients with brilliant anti-aging benefits – but what are peptides exactly? And what do peptides do? We talk you through the benefits of peptides and introduce you to the best peptide serums, moisturisers and creams out there.

What Are Peptides?

Peptides are short chains of amino acids that form the building blocks of collagen and elastin, two proteins responsible for skin’s elasticity and bounce. Without peptides, wrinkles can form and the skin begins to sag.

What Do Peptides Do?

Collagen and elastin naturally occur in the body. However, our ability to produce them slows down with age. That’s where peptides come in. They support the production of collagen and elastin to keep skin looking plumper and firmer for longer, and strengthen the skin barrier to protect against environmental damage, fine lines and wrinkles.

What Are The Benefits Of Peptides In Skincare?

Peptides, unlike fully formed proteins, are easily absorbed into the skin and combine to fight the signs of ageing. They can be seen as the flat packs of the skincare world! Their lightweight nature also allows them to be used in a broad range of skincare products.
