7 Best Peptides For Your Skin

When it comes to peptides for skin, many might be wondering if they’re worth the high price point. After all, peptides seem to fly under the radar compared to other skincare ingredients such as Vitamin C and Retinol - but here’s what makes the best peptide products for skin cult favourites around the world.


What Is a Peptide?

What is a peptide in the first place? To put it simply, peptides are small chains of amino acids. Group enough amino acids together, and you get aprotein. However, we’re not really at the protein stage - just the building block stage with peptides.

The question of are peptides good for skin isn’t even a question: peptides are able to influence your skin’s behaviour, whether that’s to produce more collagen or to support your moisture barrier!

The best peptide products for skin work alongside other skin-nourishing ingredients to nourish all aspects of your skin - luminosity, moisture, and even anti-ageing. 

What Do Peptides Do for Skin?

Peptides don’t all influence skin the same way, even though they have the same purpose: helping your skin look its best. What they actually do for skin depends on the type of peptide they are! There are five main types of peptides: signal peptides, carrier peptides, enzyme-inhibiting peptides, neurotransmitter-inhibiting peptides and antimicrobial peptides.

Signal peptides are able to literally send signals to skin cells, influencing them to behave a certain way, such as producing more collagen or hyaluronic acid, for example. 

Carrier peptides are helpful peptides for skin when used in tandem with trace elements - if you see ‘copper peptide’ listed as an ingredient, that’s a type of carrier peptide. This type of peptide benefits skin by making it easier for skin to make use of these trace elements - they carry them where they need to go, hence the name carrier peptide.

Enzyme-inhibiting peptides stop certain enzymes from working in the skin - while this sounds kind of crazy, this type of peptide is the best at helping to fade dark spots. That’s because they stop the creation of excess melanin in the skin - the pigment responsible for dark spots and other types of hyperpigmentation.

Neurotransmitter-inhibiting peptides, also called neuropeptides, have the unique power to get in the way of muscle signals, relaxing them and providing a Botox-like effect. By essentially freezing those muscles in place, wrinkles don’t get a chance to form.

Antimicrobial peptides are helpful for rebalancing skin microbiome issues - this doesn’t just include helping to get rid of acne! They can support wound healing anywhere that skin is broken for healthier, more radiant skin.
