If you’re familiar with anti-ageing skincare, you’ll have undoubtedly come across the ‘miracle ingredient’ manufacturers are now touting in their products.


Peptides are a chain of amino acids naturally occurring in the body. They link together to form the foundation of proteins such as collagen which provide skin cells with their fountain of youth.

The addition of synthetically created peptides to moisturisers, serums, face masks and face wash means that – with claims to stall the onset of ageing while reducing the appearance of existing fine lines and wrinkles – peptides are taking anti-ageing skincare by storm.

But, from a scientific point of view, are the claims about peptides to be believed or are they just more hype designed to sell skincare and baffle consumers into thinking their product can solve all their skincare woes?

To help you make informed choices about the products you put on your skin, here is our lowdown on peptides in skincare.


Peptides: The hype

The theory is that applying peptides topically sends receptors to the body that more collagen is needed. This messaging boosts the production of natural collagen which we rely on for anti-ageing goodness.

Et voila! Fine lines are decreased, skin is hydrated, and wrinkles and dark circles are diminished.


Peptides: The reality

It’s important to understand that peptides are a living tissue within the body and can only exist within a living organism.

While synthetic peptides can theoretically provide anti-ageing benefits, this comes at the cost of your skin cells, which are then exposed to toxins required to make the product work.

Further, the skin’s primary function is to protect the body and keep toxins out. While peptides may be sold as an ingredient that is good for the skin, your natural barrier function can’t define the difference between peptides and pollutants, so it works to stop the entry from the perceived toxin in the exact same way.

While peptides are a natural protein, the peptides in your skincare are produced entirely in a lab with no natural benefit whatsoever and formulated alongside synthetic (and potentially harmful ingredients) that can become trapped in the protective dermal layer of your skin causing irritation.

Look out for greenwashing tactics

It’s easy to greenwash products that contain peptides (you can find out more about greenwashing here) with some simple wordsmithing.

Stating that peptides can boost natural collagen production can make the consumer think they’re doing something good for their skin when they’re actually loading their systems with toxins to achieve results.


Peptides: The alternative

Amino acids are the building blocks of human cellular structure and are essential to our wellbeing but applying skincare products with so-called peptides has no benefit to the skin.

Rather than opt for synthetic peptides in your skincare to combat ageing, we recommend the following anti-ageing tips:

  • Simplify your skincare

Layering products and adding a multitude of synthetic ingredient to the skin can damage the protective dermal barrier causing the skin to become dehydrated, red, itching and dull.

Cut your skincare back to only the essentials (you can read our article on skin fasting here), to repair skin, improve clarity and tone, and defy the signs of ageing.

  • Apply natural vitamin C

Plant-based vitamin C (different to synthetic vitamin C often labelled as ascorbic acid) naturally stimulates the growth of collagen in the skin to reduce fine lines and wrinkles, increase skin elasticity and cover dark circles under the eyes.

Natural vitamin C is also a potent antioxidant and protects skin from free radicals that damage skin cells and increase the onset of ageing.

When choosing vitamin C in skincare, it’s important to note that ascorbic acid is entirely synthetic. While it may achieve results, these will come at the cost of increasing the toxic load on your skin with ingredients that can cause sensitisation and affect the overall function and appearance of your complexion.

Biologi is the first, and at this stage only, manufacturer in the world to use revolutionary extraction techniques to extract fully active, stable vitamin C that works on the skin just as it does in the plant.

  • Wear sunscreen

Prevention is always better than cure, and we can’t tell you enough to always wear sunscreen! Unprotected exposure to UV rays emitted by the sun is one of the fastest ways to damage cells and accelerate ageing, so don’t leave the house without sunscreen, even on a cloudy day.

While there may be scientific foundations in the use of peptides in skincare, any results achieved are purely synthetic and do not promote the skin’s natural processes as they claim to do.

At Biologi, we know that natural skincare works better than synthetics when stripped back to pure natural extracts that are fully active, undiluted with water and synthetics, and work just as nature intended.

It’s important to remember that there’s no single solution to combatting the visible signs of ageing. We always recommend receiving personalised information based on your skin type and individual skin concerns and recommend this information to be used as a guideline only.
