Next-level skin requires next-level ingredients: enter peptides. These powerful fragments of proteins have many incredible uses which we’re about to dive into. New to peptides? Start with How Peptides Can Transform Your Skincare Routine. If you’re a skin nerd (us too!) looking for a science lesson on peptides for skin, you’re in the right place . . .
What are peptides and why does our skin need them?
Did you know that peptides are not just a skincare ingredient? They’re a natural part of our bodies and we have hundreds of natural peptides in our skin. All produced by skin cells and/or released during natural biological processes, including:
- Natural antimicrobial peptides (AMPs) protect the skin from harmful bacteria, viruses, and fungi.
- Natural signalling peptides act as signals to stimulate skin repair and renewal. When collagen and elastin naturally break down into fragments (aka peptides), the body reacts and works to replace the broken-down collagen. Ta-da that’s how your body makes collagen!
- Structure proteins like elastin-derived peptides promote the production of elastin, an essential protein responsible for skin elasticity, and stimulate skin repair processes for skin health.
Why are peptides trending and revolutionising the skincare industry?
Some of the most effective peptides in skincare are bio-memetic peptides – not made from human material but practically identical to the peptides found in our natural biology. Therefore, our bodies can recognise these peptides and get them working in the same way as natural peptides, so outcomes can be transformative for many skin issues including discolouration, redness, lines, and even stubborn breakouts. Peptide-infused skincare complements in-clinic treatments like polynucleotides and chemical peels, and you can just add them to your routine immediately. There’s no acclimatisation period, no known allergens or reaction potential.
Is there a best peptide to support ageing skin?
Yes, tripeptides are a type of peptide composed of three (surprise!) amino acids linked together by peptide bonds. Their small molecular size allows them to penetrate the skin more effectively compared to larger proteins. They can be fragile, but biochemists attach them to an oil molecule known as a palmitoyl to help them get over the surface of the skin and get the goods where they need to be! That’s why when you look on the ingredient list you often see palmitoyl (oil) tri (three) peptide . . .
. . . Palmitoyl tripeptide-38 – also known as MATRIXYL® Synthe'6® is used widely in skincare as it works to improve skin architecture from the inside out for firmer, plumper skin that’s hydrated and bouncy. (The founder of MATRIXYL® Synthe'6® is the director of our scientific committee – so we’ve got the inside scoop!) Our no.1 bestselling serum year after year Ultimate Boost Serum sets the gold standard for peptides with a blend that includes clinically proven tripeptides and works to strengthen and restore the moisture barrier and powerfully hydrate all skin types. You’ll also find MATRIXYL® Synthe'6® in:
- EverActive C&E + Peptide, does so many skin jobs in one – we’re talking powerful protection against free radicals and brightening with vitamin C. This serum is clinically proven to reduce the depth and volume of wrinkles, improve surface homogeneity, and even out complexion within 56 days* (slam dunk!)
- Our eye collection, yes get MATRIXYL® Synthe'6® in your daily eye cream AluminEye®, smooth it on with your night-time Retinol Eye Gel, or get instant relief and a tripeptide boost with our Eye Rescue Pads.
What other peptides are trending?
Other peptides trending (for good reason) include copper peptide, which is soothing, protective and revolutionising skin restoration for sensitive and post-procedure skin, find it in our Recovery Balm.
Dipeptides like our β-White, a liposome-encapsulated peptide (oligopeptide-68) work to target skin discolouration and uneven skin tone – see our incredible radiance-boosting and dark spot-fighting EvenTone Serum.
These tiny fragments of protein offer so much for our skin with zero side effects, it’s a no-brainer – get peptides working for you with a daily skincare routine peppered with peptides!
