Peptides have earned a reputation as a silent powerhouse in dermatology. They are praised for their ability to heal skin, slow the ageing process, and stimulate the production of collagen and elastin. At their most basic level, peptides are short chains of amino acids that form the building blocks of proteins such as collagen, elastin, and keratin. These proteins are essential for maintaining firm, youthful-looking skin.
Peptides work by sending signals to skin cells to produce more collagen and elastin, which naturally decline with age. They also help repair damaged skin and improve overall texture. Dermatologists favour peptides because they are generally well tolerated and can be used alongside other active ingredients. Holistic aesthetician Amity Murray and board-certified dermatologist Dr Nicole Ruth both recommend incorporating peptides into a daily skincare routine for long-term anti-ageing benefits.
Dr Nicole Ruth explains that different types of peptides target different concerns. For example, palmitoyl pentapeptide mimics the skin’s own repair signals, essentially telling the skin to renew itself. This makes it effective for improving fine lines, firmness, and overall skin texture. Because the palmitoyl group makes the molecule small and lipid-linked, it penetrates the skin more easily than some other peptides, delivering anti-ageing benefits deeper into the dermis.
Amity Murray notes that peptides can be introduced at any stage of a skincare journey. They are safe for sensitive skin and can be layered with other products. The key is to choose formulations that contain a variety of peptides, as different sequences target different pathways.
This Korean skincare launch combines PDRN polydeoxyribonucleotide with a peptide complex. PDRN supports skin repair and regeneration, improving elasticity and overall skin quality. The peptide complex boosts collagen production and skin firmness over time. Hydrating humectants attract moisture for an immediate plumping effect, while niacinamide strengthens the skin barrier and improves radiance. Key ingredients include Rose PDRN, a five-peptide complex, niacinamide, and adenosine. It is priced at £17 on Amazon currently £14 with an 18% discount and £20 at Sephora.
This viral serum from Mizon is both multi-peptide and multipurpose. It provides hydration, improves skin texture, and brightens skin tone thanks to a blend of seven peptides. The peptides work alongside niacinamide, allantoin, and mixed-weight hyaluronic acid. The lightweight, water-like texture allows fast absorption and pill-free layering with other products. Key ingredients include glycerin, niacinamide, allantoin, hydrolysed hyaluronic acid, sodium hyaluronate, and a peptide blend consisting of hexapeptide-8, palmitoyl tripeptide-5, acetyl tetrapeptide-5, palmitoyl pentapeptide-4, cetyl hexapeptide-38, nonapeptide-1, and pentapeptide-18. It is suitable for dry, combination, and acne-prone skin types. The formula is free from silicones, phthalates, parabens, mineral oil, alcohol, and fragrance. It comes in a 150ml size and costs £19 on Amazon.
Holistic aesthetician Amity Murray recommends this serum for people just starting their skincare journey or anyone wanting a minimal routine. She says it “provides hydration, smooths lines, and is safe for sensitive skin.” The formula contains collagen peptides and is affordable, so users can generously apply it to the face, neck, and décolletage. It is best for dry, dull skin and is not fragrance-free. Currently priced at £15 on Amazon and £12 at Sephora a 20% discount .
Dr Nicole Ruth describes this as a high-tech serum featuring a 30% peptide complex formulated with micro molecules for better skin penetration. While it is on the pricier side, she explains that it is a great option for patients looking to smooth fine lines while also hydrating the skin and adding a healthy glow. Unlike some products that take time to show results, this serum delivers noticeably plumper, more hydrated skin within a week. Key ingredients include lactic acid and glycolic acid. It is best for mature skin, fragrance-free, and costs £79 at Medik8, Sephora, and Lookfantastic.
Dr Nicole Ruth explains that copper peptides act as multi-tasking repair agents. This serum helps boost collagen and elastin while calming inflammation and supporting healing, making it a must-have for restoring bounce and glow, especially in ageing or compromised skin. Like all The Ordinary products, it is affordable at £29 on Amazon and easy to add to a routine. However, Dr Ruth notes that research is still evolving and more studies are underway to fully understand copper peptides’ role in dermatology. Key ingredients include hyaluronic acid and peptides. It is suitable for all skin types and fragrance-free.
This product from Hailey Bieber’s Rhode line is an easy addition to an existing routine. Dr Ruth says it is a favourite for patients aiming to achieve a hydrated, glass-skin glow without irritation. The minimalist serum provides a dewy finish and barrier-boosting peptides. Key ingredients include niacinamide, peptides, hyaluronic acid, and marula oil. It is suitable for all skin types, fragrance-free, and costs £32 on Rhode Skin’s website and £32 at Sephora.
Vogue contributor Deanna Pai describes this serum as “the next best thing to a needle.” The formula contains biomimetic peptides and 10% argireline to target expression lines while smoothing and refining skin texture. Dr Nicole Ruth does not like to compare any topical product to Botox, but she says the results are promising and that it can help soften fine lines. She explains that argireline helps inhibit neurotransmitter release at the neuromuscular junction, which can soften the appearance of dynamic wrinkles. Key ingredients include hexapeptide, dipeptide, 5% PHA, niacinamide, and laminaria. It is best for mature skin, fragrance-free, comes in a 30ml size, and costs £135 at Lookfantastic.
Pronounced sagging and crepiness can occur when skin has lost significant elasticity. This serum targets that problem while improving skin barrier function to support healthy cellular renewal. It combines a growth factor complex with other actives known for tightening, firming, and rejuvenating skin. Key ingredients include a 3% sh-Oligopeptide-1 Growth Factor Complex, a 9% lifting peptide complex, MSM, phospholipids, copper lysinate, and glycolipids. It is a serum to be used after cleansing, in the morning and/or evening. Priced at £176 at Cult Beauty and £47 at Sephora.
This high-performance formula is designed to tackle loss of firmness and elasticity on the face or neck by encouraging collagen production. It uses peptides and the brand’s own trademarked Growth Factor Mini Protein to restore skin and encourage firmness. In an independent clinical trial, elasticity was increased in just one week, and hydration improved by 35%. Key ingredients include Growth Factor MiniProtein, NAD+ Longevity Booster, and Anti-A.G.E. Peptide. It is intended for those with deep wrinkles, comes in a 50ml size, and costs £79 at Medik8, Lookfantastic currently £63 with a 20% discount , and Sephora.

This fragrance-free moisturiser is a top pick for sensitive skin types. It feels great on the skin and layers nicely under SPF or makeup. According to Dr Nicole Ruth, it is packed with palmitoyl pentapeptide, a peptide known for stimulating collagen and elastin production. She explains that it works by mimicking the skin’s own repair signals, essentially signalling the skin to renew itself, making it effective for improving fine lines, firmness, and overall skin texture. Because the palmitoyl group makes it small and lipid-linked, it penetrates the skin more easily than some other peptides, delivering anti-ageing benefits deeper into the dermis. Key ingredients include collagen peptide, niacinamide, and provitamin B5. It is best for dry, ageing, and textured skin, fragrance-free, and costs £18 on Amazon currently £16 with an 11% discount .
Touted as one of the best peptide creams, this affordable option from InnBeauty Project offers a clean, effective formula. Amity Murray says it “provides profound hydration while minimising lines and wrinkles.” Users accustomed to lighter water creams may find it slightly heavier at first, but it does not cause breakouts or leave behind a tacky residue.

When shopping for peptide skincare, experts recommend looking for a variety of peptides in the ingredient list. Different peptides target different skin concerns, so a blend can provide broader benefits. Products that combine peptides with other active ingredients like niacinamide, hyaluronic acid, or growth factors can enhance results. Dr Nicole Ruth advises that peptides can be used both morning and night, and they layer well with other products such as vitamin C, retinol, and sunscreen. Amity Murray suggests starting with a serum if you are a beginner, as serums typically have higher concentrations of peptides than creams.
