The Power of Peptides in Skincare

Peptides are in the spotlight as one of the forerunners in cutting-edge skincare science. 



Peptides are short chains of amino acids, linked together by peptide bonds. There are 20 individual naturally-occurring amino acids which can be linked together in any order to give millions of different peptide combinations, with each assisting with different skin concerns. Peptides are also the building blocks of proteins. Our skin is naturally overflowing with different kinds of proteins and peptides, including some of the most important; collagen and elastin, which are both responsible for retaining the skin’s natural strength and resilience.

Every peptide has a unique superpower to target different skin concerns. Whether your goal is to minimise visible signs of ageing, prevent breakouts or tackle hyperpigmentation, our advanced range has the perfect peptide for you.



There are many different types of peptides that are commonly used in skincare for different purposes. However, not all peptides are created equal, and the potency of a peptide will depend upon its specific properties and the formulation of the product that it’s used in.


1. They can help to improve the skin barrier

The skin barrier is the body's first line of defence against pollution, bacteria, ultraviolet rays and other toxins. The skin barrier is very delicate, and it can easily be damaged by environmental stressors, pollutants, too much exfoliation and even lack of sleep. Peptides help to promote a stronger skin barrier, keeping the skin feeling resilient and supported.


2. Reduce the appearance of wrinkles

Certain peptides can also help to improve the appearance of fine lines and wrinkles and the complexion appearing firmer and more youthful-looking.


3. Enhance skin firmness

As well as helping improve the appearance of wrinkles, peptides can help to give the skin a firmer, more lifted appearance.


4. Help to even out skin tone

Peptides can also help to visibly even the skin tone, therefore reducing the appearance of dark spots and hyperpigmentation


5. Help to improve the appearance of blemish prone skin

Some peptide molecules also help improve the appearance of blemish prone skin, resulting in a visibly clarified and flawless-looking complexion.


6. Reduce the appearance of eye bags and dark circles

Peptides can also be used to help reduce the appearance of tired-looking eyes as they can visibly brighten dark circles and discolouration while diminishing the appearance of puffiness with a lifting and awakening effect.


7. Calm visible redness

If your skin is sensitive, peptides can help to reduce the appearance of redness.



All of our peptides have been expertly formulated with our CSA Philosophy in mind, and work to boost your visible results while you tailor your Medik8 CSA routine to meet your specific skincare needs. Most of our peptide formulas can be used both day and night, working to complement the visible benefits of other ingredients including antioxidants like vitamin C, vitamin A products (retinoids) and hyaluronic acid.



Depending on your skin type, all of our peptide products have the potential to help treat specific skin concerns including fine lines and wrinkles, dullness, blemishes and uneven skin tone. Using a product that you can leave on your skin for a prolonged period of time, like a serum or moisturiser, will allow the peptides to gradually penetrate the skin throughout the day and evening - maximising visible results.



Peptides can easily be incorporated into your existing skincare routine - you just need to know how to use them correctly. For optimum results, we recommend applying peptides both in the morning and evening. Medik8’s peptide formulas can also be safely layered with AHA/BHA products, as these acids will not damage the efficacy of the peptide molecule. Morning routine: Apply your chosen peptide product onto a cleansed face before your moisturiser and sunscreen. Evening routine: Apply your chosen peptide product after cleansing and before moisturiser.



Peptides might be in the skincare spotlight for their incredible anti-ageing powers but, at Medik8, we understand that peptides are so much more than just a one-trick pony. Each peptide has a different action on the skin - not just for skin ageing concerns, but also for tackling dullness, hyperpigmentation, anti-glycation, dryness, and more! At Medik8, we wanted to harness the broad range of different peptide powers in our peptide product offering. We have developed revolutionary, results-driven peptide formulations which help to amplify the results of all Medik8 CSA regimes. We use scientifically proven ingredients and advanced delivery systems alongside each carefully-selected peptide to enhance the penetration and power of the active ingredients. The perfect addition to your CSA routine, our full range of innovative peptide formulas are expertly designed to support many different skin concerns.

This award-winning formula also harnesses the powers of hesperidin to minimise the appearance of dark circles, plus glycerin to hydrate the delicate eye area.




Our peptides range has been designed with our pioneering CSA Philosophy in mind, working to boost visible results while tailoring a Medik8 CSA routine to meet your specific skincare goals.

Most of our peptide products can be used both day and night, to complement vitamin C and A products. We always recommend layering serums from thinnest to thickest consistency, to ensure that your products can absorb properly while the thicker, cream-textures can lock in all the skincare goodness.

The only exception to the rule is with Copper PCA Peptides and Bakuchiol Peptides:

Copper PCA Peptides replaces vitamin C in a morning skincare routine. The two actives are not compatible and unfortunately cancel out each other’s anti-ageing powers if used within the same routine.

Bakuchiol Peptides replaces vitamin A in an evening skincare routine. As our vitamin As can only be used at night, Bakuchiol Peptides is a great option to boost your skincare routine during the day. However, as bakuchiol and vitamin A have similar effects on the skin, at nighttime we would recommend layering your vitamin A with Liquid Peptides or Clarity Peptides to gain extra visible benefits.

Enhance your CSA skincare routine today and discover your perfect peptide blend.

*Proven via an independent consumer study Tested over 4 weeks on 50 participants aged 35-70 with hyperpigmentation skin concerns

**Of course, due to ethical considerations the Bakuchiol Peptides formula has not been tested on pregnant women, but there is nothing in the formula which is known to be an issue (eg vitamin A or high levels of exfoliating acids). If you are at all concerned, always consult your doctor.
