Skin treatment trends are ever-changing, with a variety of new products and skincare methods hitting the market every single day. But while many up-and-coming products make bold promises, peptides remain a biological necessity. Proven to support skin health, peptides are a simple and effective means of skincare that your clients can apply at home. 


In this guide, NOON Aesthetics will introduce you to the impact of peptide skincare products. We’ll be answering questions like, ‘What are peptides in skincare?’ and ‘What do peptides do?’ to help you best recommend NOON’s skincare products to your clients.

What are Peptides?

What are peptides, exactly? Peptides are actually amino acids that help the body produce a range of proteins, such as collagen. Whilst naturally occurring within the body, peptide treatments can essentially fool the body into thinking it needs to produce more collagen, triggering a repair response that helps support the appearance of the skin.

What do Peptides Do?

Peptides aim to support skin health and appearance in several ways. Boosting the skin’s collagen production, peptides help in the following ways:

  • Boosts Collagen and Elastins: Peptides work to strengthen the skin’s elasticity. This makes the skin appear firmer and plumper, reducing the appearance of fine lines, wrinkles, and sagging with increased hydration and moisture. 
  • Supports Barrier Health: Peptides can also help repair the skin’s barrier, protecting it from further environmental damage from bacteria and pollution.
  • Skin Brightening: Peptides are also known to brighten the skin and target hyperpigmentation disorders, promoting a balanced, even complexion. 

Are Peptides Safe?

Peptides are considered safe skincare treatments across a breadth of skin types, including reactive skin, dry skin, sensitive skin, and more. Given that peptides are biomimetic, meaning that they mimic what is already happening in the body, they are well-tolerated and promote completely natural benefits. Peptides are generally considered safe for use during pregnancy and breastfeeding.


If you’re using injectable peptides, however, there are certain risks you should be aware of, including contamination and infection. If properly administered, the treatment poses no real risk beyond mild irritation or sensitivity after use.
