The Ordinary Multi-Peptide + Copper Peptides 1%: An Honest Review

Search interest in this serum dwarfs the rest of the copper peptide category, and for good reason: it put GHK-Cu within reach of anyone with $32. This review looks at what the formula actually is, what The Ordinary does better than almost everyone, and where the famous peptide buffet leaves a copper-focused shopper wanting more. No takedowns here, just the label, the brand's own published guidance, and honest context.

01 /What this serum actually is

Multi-Peptide + Copper Peptides 1% is The Ordinary's flagship peptide serum, the product long known as "Buffet" + Copper Peptides 1% before the brand renamed its lineup. As of August 2026 it sells for $32.00 for 30 ml on theordinary.com, and you can find it at most major beauty retailers. The nickname was accurate: this is a buffet, not a single dish.

The brand describes the formula as combining five peptide technologies. Alongside the copper peptides you get Matrixyl 3000 (palmitoyl tripeptide-1 with palmitoyl tetrapeptide-7), Matrixyl synthe'6 (palmitoyl tripeptide-38), SYN-AKE (a so-called smoothing dipeptide), and Argirelox (acetyl hexapeptide-8 with pentapeptide-18), all suspended in a hyaluronic-rich base. The copper part of the name refers to Copper Tripeptide-1, better known as GHK-Cu, the blue copper complex with a decades-long research trail on collagen-related pathways in laboratory models.^[1][2]

The pitch, in plain English: one bottle that covers the whole peptide waterfront and supports the look of firmer, smoother skin, with copper as the headline guest rather than the whole show.

02 /What The Ordinary gets right

Credit where it is due, because a lot is due here.

Price and access

At $32 for 30 ml, this is among the least expensive ways to put a credible copper peptide product on your shelf, and it is stocked nearly everywhere skincare is sold. For a curious first-timer, the barrier to entry is essentially zero. That accessibility, more than any single ingredient, is what built The Ordinary's reputation.

Conflict transparency

This is the underrated star of the product page. The Ordinary publishes an explicit do-not-combine list for this serum: direct acids, direct vitamin C, EUK 134, retinoids, strong antioxidants, resveratrol with ferulic acid, and salicylic acid. Most brands leave you to figure out routine chemistry on your own; The Ordinary tells you up front, in writing, that copper peptides want their own slot. That level of candor respects the customer and prevents a lot of irritated skin.

Peptide pedigree

The supporting cast is not filler. Matrixyl-type palmitoyl peptides have published human facial data behind them,^[4] and the broader peptide category has been reviewed extensively in the cosmetic science literature.^[5] GHK-Cu itself carries one of the deepest mechanistic dossiers in cosmetics.^[3] Whatever else you say about the buffet, the dishes are real.

03 /The buffet question: where GHK-Cu fits

Now the honest part. The 1% in the name is the copper peptide figure The Ordinary gives you, and to be fair, a named percentage is more than many brands offer. What the product page does not do is unpack that number any further. You will not find a dedicated GHK-Cu breakdown, an explanation of how the copper dose was chosen, or much copper-specific education at all. The page describes the formula's "direct copper peptides" and moves on to the ensemble.

That matters because a buffet, by design, splits its attention. Five peptide technologies share one 30 ml bottle and one price point, which means the formula is optimized for breadth rather than for maximizing any single active. If you arrived here because you specifically want copper peptides, you are buying GHK-Cu plus four other technologies you may not have asked for, and the copper-specific details stop at the headline number. Our copper peptide percentage guide explains why disclosed, comparable numbers make a category easier to shop, and our guide to spotting an underdosed copper peptide serum covers the label-reading skills that apply to every brand, this one included.

There is an honest counterpoint, and it deserves space: diversification is a legitimate strategy. Different peptides are studied for different signals, and the evidence depth varies peptide by peptide.^[5] If you are agnostic about which peptide your skin responds to, a blend hedges that bet in a way no single-active serum can. The buffet is only a weakness if copper was the point.

04 /The conflict list, translated

The Ordinary's conflict list is strict, and it reshapes your week more than most buyers expect. Here is what it means in practice.

• No direct acids in the same routine: glycolic, lactic, mandelic and salicylic acid steps move to a different time of day or different evenings entirely.
• No direct vitamin C alongside it: L-ascorbic acid and similar formats belong in the opposite routine, morning versus evening being the common split.
• No retinoids in the same session: retinol or retinal users typically alternate nights or run peptides in the morning and retinoids at night.
• Strong antioxidants get spacing too: the brand's own EUK 134 and resveratrol-ferulic products are named directly, which is refreshingly specific.

None of this is unique to The Ordinary's formula; it is standard copper peptide routine hygiene, and it matches the general compatibility rules in our complete guide to what not to mix with copper peptides. The difference is that The Ordinary says it plainly on the product page, which we wish were the industry norm. If your current routine leans hard on acids or retinoids, budget for some restructuring no matter whose copper serum you buy.

05 /Who it suits, who it frustrates

It suits you if: you are peptide-curious rather than copper-committed, you want one affordable serum that covers several bases, your routine is simple enough to give peptides their own slot, and you like buying from a brand with enormous community documentation. As a first peptide serum, it is an easy recommendation.

It will frustrate you if: you chose GHK-Cu deliberately and want to know exactly how much of it you are applying, you want copper-specific education from the brand you are buying from, or your routine is built around daily acids or retinoids and you are unwilling to reshuffle. New users with reactive skin should also note that any copper peptide product deserves a slow introduction; our copper peptide side effects and safety guide covers patch testing and the start-low schedule that applies to every serum in this category.

06 /How it compares to a dedicated copper serum

The clearest way to frame the decision is what each approach lets you know and control.

For transparency, since we compete in that second column: our own Glow GHK-Cu Copper Peptide Serum discloses 0.2% GHK-Cu on the label at $49.99 for 50 ml, so you can run the price-per-milligram math yourself and compare it against anything on this page. Whether a buffet or a specialist serves you better is genuinely a matter of what you want from the bottle, not a matter of one being superior.

07 /The honest verdict

Multi-Peptide + Copper Peptides 1% is a very good product judged by what it sets out to be: the most accessible multi-peptide serum on the market, with copper along for the ride and a conflict list that treats customers like adults. The price is fair, the peptide lineup is legitimate, and the brand's routine guidance is better documented than almost any competitor's.

Judged as a copper peptide serum specifically, it is a compromise by design. The GHK-Cu story stops at the 1% headline, the copper shares shelf space with four other technologies, and shoppers who want to know and control their copper dose will not find that precision here. That is not a scandal; it is a positioning choice, and The Ordinary has never pretended otherwise.
