Best Peptide Serums of 2026
Nine peptide serums compared by concern, with the named peptides, price and size from each brand's page, and which ones publish a peptide percentage.
Last updated: October 9, 2026
The best peptide serum for wrinkles is Medik8 Liquid Peptides Advanced. It is the only serum here that publishes both a peptide count and a total peptide percentage: a 30% multi-peptide complex of 13 peptides (copper peptides and Matrixyl 3000 among them). It costs $95 for 1.0 fl oz (30 mL) on its US site. If you want glow and expression lines handled in one serum, ProGlow Glass Skin is the only serum here with Snap-8, which it pairs with Salmon DNA (PDRN), copper peptide (GHK-Cu) and Nonapeptide-1 for $82. For firmness on the face and neck, Allies of Skin publishes a 9% peptide complex, at $188.00 USD. On a drugstore budget, L'Oréal Revitalift Triple Power names a Tri-Peptide Complex for wrinkles and firmness at $24.99.

How we chose
We started from 19 peptide skincare products, and kept the 9 that met the criteria below. Details come from each company's own pages and the sources linked in each entry, 46 pages in all, read on October 9, 2026.
Peptide disclosure: The brand's own product page and published ingredient (INCI) list: whether it names each peptide and states a peptide concentration.
Fit to a named concern: The concern the brand's product page says the serum targets (such as fine lines, firmness, pores or glow), set against the peptide classes a peer-reviewed dermatology review links to that concern.
Published price and size: The price and bottle size on the brand's own US product page, or a US retailer's product page when the brand's page cannot be read, checked on the research date.
The 9 best peptide serums
1. Medik8 Liquid Peptides Advanced
Medik8 Liquid Peptides Advanced is the pick for wrinkles, and the only serum here that publishes both a peptide count and a total peptide percentage. Medik8 states a 30% multi-peptide complex of 13 peptides; copper peptides and Matrixyl 3000 are among them. Its printed ingredient list names palmitoyl tripeptide-38 and palmitoyl tripeptide-5 among others. It is one of three serums on this list with a published peptide percentage, and 30% is the highest of them.
Medik8 positions it for wrinkle reduction: expression lines as well as deep-set wrinkles. It is fragrance free and Vegan Society certified. Medik8 says to apply it after cleansing in the morning and/or evening. It goes on the neck and décolletage as well as the face.
On Medik8's US site it costs $95 for 1.0 fl oz (30 mL). The Ordinary's copper peptide serum, which also names Matrixyl 3000, is $32.00 USD for 30 ml. For the higher price, Medik8 names a longer peptide list and publishes the 30% figure.
Medik8's results for expression lines and deep-set wrinkles come from a clinical study of 34 participants, which the brand describes as independent. The study measured results at 10 minutes and at 8 weeks. Medik8 also recommends a patch test at least 24 hours before first use.
2. ProGlow Glass Skin
Glass Skin Regenerative Peptide Serum is ProGlow's flagship facial serum. It pairs Salmon DNA (PDRN) with three peptides: Snap-8 (acetyl octapeptide-3), copper peptide (GHK-Cu, listed as copper tripeptide-1) and Nonapeptide-1, with Centella alongside them. It is designed to help skin look plumper, smoother and more refined with a luminous, glass-like finish. It is also the only serum on this list with Snap-8, an eight-amino-acid relative of Argireline (acetyl hexapeptide-8), the expression-line peptide that seven of the other eight serums use.
Each ingredient has a stated job. Snap-8 works to visibly relax the look of expression lines; Salmon DNA helps support the look of skin renewal; copper peptide supports the look of firmer skin; Nonapeptide-1 helps skin tone look more even; centella helps calm and soothe skin's overall appearance. The key benefits are helping visibly reduce the look of wrinkles, supporting plumper-looking skin, refining the appearance of enlarged pores and promoting a smoother, glass-like glow. That suits a shopper who wants glow and expression lines handled in one serum.
ProGlow directs Glass Skin for morning and evening use: a thin layer on clean skin, under moisturizer. Like ProGlow's other serums, it is formulated without parabens, sulfates, mineral oil, drying alcohols, added dyes or formaldehyde-releasing preservatives. It does contain fragrance, which matters if fragrance bothers your skin, and it is not vegan, since Salmon DNA is animal-derived.
Glass Skin costs $82, the same price as ProGlow's Daily Lift and Recovery serums.
3. Allies of Skin Multi Peptides & GF Advanced Lifting Serum
Allies of Skin says this serum is formulated to visibly firm, which makes it the firmness pick here. It lists a 9% peptide complex plus a 3% growth factor complex.
Allies of Skin's own listing does not spell out the peptides. DermFND's reading of the ingredient list counts more than ten. Among them are palmitoyl tripeptide-1 and tetrapeptide-7 (Matrixyl 3000), acetyl hexapeptide-8 (Argireline) and copper tripeptide-1. DermFND lists it as fragrance free and says to press it into the face and neck morning and evening.
Price is the drawback. At $188.00 USD for 1 fl oz on the brand's site, it is the second most expensive serum here, after Eighth Day. DermFND notes that it sits in prestige pricing territory, that a dedicated Matrixyl 3000 serum from a more modest brand will deliver most of the peptide work for a third of the price, and that independent clinical studies on this specific formulation are limited.
4. The Ordinary Multi-Peptide + Copper Peptides 1% Serum
The 1% in the name refers to copper peptides, and copper peptides are the reason to pick this serum. At $32.00 USD for 30 ml it is the least expensive of the three serums here that give a peptide percentage, though The Ordinary gives no total peptide percentage.
It names GHK-Cu alongside four peptide technologies: SYN-AKE, Matrixyl synthe'6, Matrixyl 3000 and ARGIRELOX. On the ingredient list, copper tripeptide-1 is the first peptide and comes fourth overall; acetyl hexapeptide-8 and other peptides follow it.
The Ordinary lists its targets as advanced signs of aging and dryness, and says it helps to improve the appearance of fine lines. The brand lists it as alcohol-free and vegan. It was previously sold as Buffet + Copper Peptides 1%. The brand says to apply a few drops to the face in the morning and evening.
It does not combine easily with other actives. The Ordinary recommends avoiding it with other direct acids, retinoids, or strong antioxidants like vitamin C, and suggests a patch test if you have sensitive skin. On 9 October 2026 the US page showed an "Email me when in stock" option.
5. Eighth Day The Regenerative Serum
Eighth Day The Regenerative Serum is for someone treating several concerns with one serum and willing to pay the most on this list for it. Eighth Day lists four targets: fine lines and wrinkles; loss of volume; firmness and elasticity; dull skin. It was developed by dermatologic surgeon Dr. Antony Nakhla.
Most of its peptides sit inside Peptide-rich Plasma, the brand's proprietary complex, whose ingredient list includes acetyl hexapeptide-8 and palmitoyl tripeptide-5 among others. Nonapeptide-1 and tripeptide-1 are among the peptides listed outside it. Eighth Day says the serum has the highest concentration of its Peptide-rich Plasma but publishes no percentage.
It costs $225.00 for 30 ML, which the brand calls a 6-8 week supply, and also comes in sizes from 15 mL to 100 mL. Eighth Day says to use it on the face and neck morning and evening. Skinsort's ingredient analysis finds no fragrance ingredients in the published list.
Two things to weigh: the formula includes glycolic acid, an exfoliating acid, which matters if your skin is sensitive, and the brand's results come from consumer perception studies and skin measurements with 30 participants over a 4 week period.
6. YISE Beauty Xtreme Glow Dewy Peptide Plumping Serum
YISE says Xtreme Glow can be worn alone, under makeup, or mixed in with foundation for a luminizing effect, and lists it as brightening as well as hydrating and firming. That makes it the glow pick.
Its two named peptides are tripeptide-1 and hexapeptide-9. YISE says they visibly smooth fine lines and restore elasticity for a firm, bouncy look. No peptide percentage is given. The page lists it as dermatologist tested and Leaping Bunny certified, and the clinical test YISE cites covered 30 participants after 4 weeks of use. YISE says to apply 2-3 pumps in the morning, before SPF.
It costs $68 for 30 mL / 1 fl. oz., or $57.80 with a subscription that saves 15%, which puts it below Medik8 and ProGlow Glass Skin and well above the drugstore options.
On 9 October 2026 the product page showed it out of stock with a waitlist.
7. L'Oréal Paris Revitalift Triple Power Tri-Peptides Age-Defying Serum
At $24.99 on L'Oréal's US site, Revitalift Triple Power is the drugstore pick for wrinkles and firmness. L'Oréal names a Tri-Peptide Complex of Matrixyl, Argireline-Amplified Peptide and Carnosine. On the ingredient list, palmitoyl tripeptide-1, palmitoyl tetrapeptide-7 and acetyl hexapeptide-8 are among the last ingredients.
The brand says it helps visibly reduce the appearance of wrinkles and fine lines, and lists loss of firmness and elasticity among its best-for uses. The peptides share the formula with vitamin C and hyaluronic acid. L'Oréal says to use it morning and night between cleanser and moisturizer. It also says it suits all skin types, including sensitive skin.
It is not fragrance-free: the ingredient list includes parfum and benzyl salicylate, which matters if fragrance bothers your skin. L'Oréal gives no peptide percentage or bottle size on the page, and its 12-week claim for firmness comes from a clinical test L'Oréal cites.
8. Biodance Pore Perfecting Collagen Peptide Serum
Biodance calls this serum advanced pore care, and it is the pick here for visible pores. At $21.90 on Biodance's site it is also the lowest price on the list. Firming and hydrating are the other uses Biodance lists.
It names ten peptides on its ingredient list: tripeptide-1, acetyl hexapeptide-8, copper tripeptide-1, palmitoyl tripeptide-5, sh-oligopeptide-1, pentapeptide-4, palmitoyl tripeptide-38, hexapeptide-9, hexapeptide-12 and palmitoyl pentapeptide-4. Biodance says they were selected to help visibly firm skin and tighten pores. It goes on after cleansing or toning, 2-3 pumps massaged in circular motions until absorbed.
Biodance publishes no peptide percentage. Stock is unclear: on 9 October 2026 the brand's related-products list marked the serum as Sold Out.
9. SkinCeuticals P-Tiox
For expression lines, the pick is SkinCeuticals P-Tiox. A retailer describes it as a peptide complex of a hexapeptide and a dipeptide, acetyl hexapeptide-8 and dipeptide diaminobutyroyl benzylamide diacetate, aimed at the look of contraction lines. Alongside them are 5% PHA, 5% niacinamide and laminaria extract.
A US retailer, Gallaher Plastic Surgery & Spa MD, says P-Tiox reduces the appearance of contraction lines (fine lines and wrinkles) and lists it as free of perfume and parabens. It sells P-Tiox at $150.00 for 30 mL / 1.0 fl oz. No peptide percentage is published for it.
The retailer that publishes the ingredient list gives the directions: twice a day, 5 to 6 drops dabbed on the forehead, cheeks and chin. In the morning it goes after a vitamin C serum and before sunscreen.
The ingredient list includes alcohol denat., which Skinsort flags as possibly worsening dryness or irritation.
How to choose a peptide serum by type and concentration
Start with the concern, then check which kind of peptide the serum names. A peer-reviewed review in the journal Cosmetics sorts topical cosmetic peptides into four classes:
Signal peptides trigger a signalling cascade; the review describes them as increasing collagen and elastin among other matrix proteins. Its example is a combination of pal-GHK tripeptide and pal-GQPR tetrapeptide, marketed as an anti-wrinkle compound.
Carrier peptides deliver or stabilize trace elements such as copper and manganese. Copper tripeptide (Cu-GHK) is the example the review covers, and it is the GHK-Cu named by The Ordinary and included in ProGlow Glass Skin. The review says copper tripeptide is still under research for the details of its effectiveness.
Neurotransmitter inhibitor peptides are described as relaxing muscles to reduce and soften wrinkles and fine lines. SkinCeuticals P-Tiox and ProGlow Glass Skin are both pitched at expression lines.
Enzyme inhibitor peptides directly or indirectly inhibit enzymes; soy oligopeptides are one example the review names.

Peptide serum questions
What are the benefits of a peptide serum?
The benefits a peptide serum can claim are cosmetic: the review in Cosmetics notes that efficacy claims for cosmeceuticals are restricted to improving the appearance of skin. Within that, brands aim their serums at different concerns. Medik8 positions Liquid Peptides Advanced for wrinkle reduction; Allies of Skin says its serum is formulated to visibly firm; YISE lists its serum as brightening; Biodance positions its serum as pore care.
How long does a peptide serum take to show results?
The timelines on serum pages come from the brands themselves. ProGlow says peptides work gradually, with visible results over 4 to 8 weeks of consistent use. L'Oréal's clinical claim for Revitalift is set at 12 weeks, and Medik8's study measured at 10 minutes and 8 weeks.
How often should you use a peptide serum?
Follow the label. Most serums here are directed for morning and evening use. YISE says to apply its serum in the morning before SPF; ProGlow directs Glass Skin for morning and evening use, under moisturizer. Before using any new serum, the American Academy of Dermatology recommends applying it to a quarter-sized test spot twice daily for seven to 10 days, and washing it off and not using it again if a reaction develops.
Which peptide serum to start with
If one concern decides it: Medik8 Liquid Peptides Advanced for wrinkles, Allies of Skin for firmness, YISE Xtreme Glow for glow, SkinCeuticals P-Tiox for expression lines and Biodance for visible pores. ProGlow Glass Skin is the one to look at if you want glow and expression lines handled by one serum, and it is the only serum here built on Snap-8 rather than the more common Argireline.
