What are peptides?

Peptides are short chains of amino acids. Amino acids are the building blocks for proteins. Proteins are the fundamental building blocks for the skin.

In the skin, peptides simulate collagen production, cell metabolism, and improve skin firmness. Peptides have been shown to improve tissue repair, and improve elasticity. All of these benefits translate to preventing aging skin, and helping aging skin look more youthful.

What kind of skin likes peptides?

Peptides are far less irritating than other ingredients used to improve quality of aging skin – so they are suitable for all skin types, even sensitive.

Paired with hydrators like hyaluronic acid and/or antioxidants like Vitamin C, peptides give an even more powerful boost to skin. This can be a great option even if your skin isn’t aging, just to give it some more nourishment and plumpness.

How should I use peptides?

As peptides are not harsh, stripping, or photosensitizing, most peptide-containing products can be used morning or night. Follow the instructions on the label or from your skincare professional.

Keep in mind that, amazing as they sound, peptides are not the end-all be-all for healthy skin. As part of a high-quality product, and in a high-quality skincare routine, they will only help and amp up your skin. But they can’t be a solo hero!

The last peptide on the list- Argireline- has a specific and incredible function that serves as a vital cog in any anti-aging product. Argireline is a neuropeptide that has been proven to actually act as a barrier between neurotransmitters from facial nerves having a similar effect to botox, making your skin more smooth and more firm.
