The Benefits of Collagen Peptides for Skin

Peptides for skin

Collagen peptides are an effective anti-aging skincare ingredient suitable for all skin types, including sensitive, dry and acne-prone skin. With many options from No7 to choose from, peptides for skin can easily be incorporated into your daily skincare routine.

Read on to discover how collagen peptide benefits the skin, as we explain what peptides in skincare are and introduce you to the best peptide skincare for a healthy, younger-looking complexion.

What are peptides?

Peptides, also known as polypeptides, are small chains of amino acids that form the building blocks for proteins like collagen and elastin. These proteins are naturally found within the skin and act as the foundations responsible for skin’s texture, tone and elasticity.

However, with age, their production depletes, with 1% of the skin’s collagen lost every year after the age of 30. This decrease contributes towards a loss of firmness, the deepening of wrinkles, and less ‘bounce’ in the skin.

What do peptides do?

Peptides support collagen and elastin production in the skin, two proteins that help the skin look and act younger. With continued use, peptides in skincare encourage a firmer, smoother and plumper appearance for healthy-looking, supple skin.

Smooth fine lines and wrinkles

Peptides may help support the skin’s natural collagen to reduce the appearance of fine lines and make the skin appear firmer.

Increase skin firmness

A key structural protein in the skin, collagen helps to maintain a taut and elastic feel.

Improve the skin barrier

Peptides work to help the skin feel strengthened. Polypeptides also have antioxidant properties.

How to add collagen peptides into your skincare routine

Applying peptide skincare that has prolonged contact with the skin, including serums, eye creams, boosters and moisturizers, allows for best results.
