Peptides… even the word itself intimates the meaning and purpose of this ingredient as it works to ‘pep’ up the skin in various ways depending on the makeup of the peptide itself. But what is this mysterious ingredient? We want to break it down for you and explain what they are and how they can work for you.

Peptides are fragments of proteins made up of amino acids.  They are short chains of amino acids that act as building blocks of proteins such as collagen, elastin and keratin. These proteins are the foundations of your skin and are responsible for its texture, strength and resilience. Without peptides, our skin is less intact which can lead to a loss of firmness, the appearance of wrinkles, a change in texture and less ‘bounce’.

There are hundreds of different peptides, all of which are made from different combinations of amino acids and when amino acids are combined in certain formulations, they make specific proteins with different affects to the skin.

Depending on the amount of amino acids within the peptide can really change the effect it has on the skin. For example- hexapeptides (which contains six amino acids) brightens the skin, while tetrapeptides (which contains four amino acids) boost elasticity and firmness in the skin. But what is great is that different peptides can be combined in a formula to give multiple benefits.

Outer Beauty

When applied topically to the skin, peptides act as little messengers, triggering skin cells to perform specific functions such as building collagen and elastin, encouraging skin to look and act younger… fabulous!

When looking for peptides in skincare, they work best alongside other products to really boost their benefits. On skincare product labels look for words that end in “peptide” – many also begin with “palmitoyl”.

Peptide molecules are small enough to penetrate the epidermis of the skin and get to work signalling to the skin to repair itself and encourage your skin’s natural production of collagen.

One of the most powerful topical peptides are copper peptides – it promotes collagen and elastic production, but  also promotes the production of glycosaminoglycans, a family of carbohydrates that maintain and support collagen and elastin, helping you to not only generate collagen, but also to maintain the collagen you generate. There’s also evidence to show that copper peptides may also encourage your skin to remove damaged collagen and elastin as well, as they engage the systems that are responsible for doing so.

With consistent use of peptides, your skin will become firmer and more elastic as it encourages your body to product more collagen, which is something that your body slows down on with age.

Some products that feature Peptides include:

You can also find peptides in supplements too, often in things like protein powders.

Peptides may be easier for your body to absorb than proteins because they are smaller – meaning they can enter the bloodstream more quickly and also could lead to less digestive issues.

The peptides in supplements may come from plant or animal sources of protein, including:

  • Eggs
  • Milk
  • Meat
  • Fish and shellfish
  • Beans and lentils
  • Soy
  • Oats
  • Flaxseed
  • Hemp seeds
  • Wheat

If you’re looking for peptides for supplemental purposes, one of the main ones you will hear about is Collagen Peptides.

If you’re looking for Collagen Peptides, they may also be called hydrolyzed collagen or collagen hydrolysate.

If you’ve ever heard people say that Collagen is too large to be absorbed when supplementing it, then you need to know about Collagen peptides. These are much smaller molecules and are also cold water soluble as well as being highly bioavailable and bioactive, so they are easily broken down by the body. They act as building blocks, renewing bodily tissues, such as skin, bones and joints and are a better option for consumption and for food supplements in comparison to regular collagen.

You may also hear about Creatine peptides, which may build strength and muscle mass. This is popular in protein powder with fitness enthusiasts and are considered to be easier for the body to digest (leading to less digestive problems) than creatine proteins.

As peptides in supplements are similar to those already found in the body and in food, they are unlikely to cause side effects to health individuals, but of course we recommend you speak to a doctor before taking any supplements.
