If you’re at all familiar with peptides, you’ll know the ingredient is banded about the beauty sphere as a miracle anti-ageing ingredient.

It has been likened to Botox; it has been compared to retinol; it’s been incorporated into skincare products the world over: but does it really work?

Let me start by saying, there is no topical skincare product currently in existence that will miraculously turn back the clock, and there is less scientific evidence available on peptides versus some of the more established components like your acids and your vitamin As. That said, these amino acids can play a role in signalling your skin to produce more collagen and elastin. That’s why they deserve a place in your bathroom cabinet.

We consulted Dr Natalie Geary, one of the leading aesthetic doctors in the UK and founder of The Light Touch Clinic to find out more.

What are peptides?

Peptides are a short string of amino acids that are linked by a peptide bond and when organised within complex structures, peptides become proteins. Peptides have several distinct functions depending on their configuration. Peptides are found naturally in the skin, but as time progresses they become less effective. That is why they are beneficial to be used within skincare, allowing your skin to have an extra boost when natural productions start to drop.

What do peptides do and why are they used in skincare?

Due to the variety of different peptides, each contribute to different roles within the body. Peptides have many uses within skincare, with the most beneficial being giving your skin a boost.

  • Anti-ageing benefits: Collagen peptides help to produce collagen and elastin, all of which are proteins found in healthy skin. An antimicrobial peptide found within the skin may help aid the production of melanin and contributes to skin whitening - therefore a synthetic version may help with hyperpigmentation and discoloration damage. Peptides can support in diminishing fine lines, wrinkles and redness.

  • Skin barrier improvement: Antimicrobial peptides studies have shown that they can help your body fight bacteria and contribute towards wound healing.

  • Antioxidants: Peptides have been proven to help repair damaged skin.

  • Skin hydration: If you suffer from dry skin, using peptides within your skincare can help provide a fresh and revitalised appearance.

  • Firm and tighten the skin: Peptides, amongst other things, help firm and tighten the skin.

  • Skin beautification: Peptides can sense that your skin needs a pick-me up and get to work.

  • Redness: Peptides can work by lessening the appearance of occasional redness within the skin. If you suffer from rosacea or flushed skin, then using a product containing peptides can help by targeting that area and reducing the redness on the surface of the skin.

How do peptides differ from retinol?

Both retinols and peptides have the potential to improve skin’s quality and appearance over time. Even though retinols are incredible exfoliators, they require caution when exposed to UV rays. As you can only use them at night, retinols act very slowly.

Peptides on the other hand produce faster results if they are compatible with your skin type. Peptides do require a little more research due to the many different varieties within the peptide family, however consulting a dermatologist will fasten the process of pinpointing what works for you.

Peptides work for those who have sensitive skin as they are less invasive than retinol. So, you can use peptides alongside other skincare ingredients without having to be concerned whether you will get a negative reaction. Retinol is used in anti-aging products due to its strength, so mixing ingredients with this can cause a reaction and is not recommended.

What is the best product type to include peptides in?

Use a product that you can leave on your skin for a prolonged period like a moisturiser to allow the peptides to penetrate the skin throughout the day and evening - do not leave out the eyes. By including an eye cream with peptides within, you are ensuring that the lines and wrinkles around the eye area, as well as the dark circles are being targeted. The same for face creams - ensure that your peptide eye product remains on the skin for some time to allow the ingredients to penetrate fully. Applying at night is recommended.

Which ingredients should you pair with peptides?

Hyaluronic acid: The pair make a potent skin duo and can remain highly effective whilst ensuring the protective barrier remains healthy and in its happiest state. You will also find that hyaluronic acid is able to benefit from being layered with a peptide serum as it will absorb the water found in the formulation and lock it into place.

Peptides are great for anti-ageing; however, they do not replace products such as retinol that are strong active ingredient-based products. You will want to incorporate both retinol and peptides into your nightly routine. You can use them together at night, or just use peptides throughout the morning and daytime and then retinol in the evening.
