Drunk Elephant Protini is sold as a “polypeptide” firming moisturizer with a nine-peptide complex. On the label, the first peptide — sh-Oligopeptide-1 — appears at ingredient number ten, after water, an emollient, glycerin, three emulsifiers, a seed oil, a ferment and a botanical extract. The copper compound in the formula is Copper Palmitoyl Heptapeptide-14, which is not the same molecule as copper tripeptide-1 (GHK-Cu), the copper peptide most of the published research is actually about.
We quote ingredient lists so you can check them yourself. Here is Protini’s, verbatim from the Drunk Elephant product page (drunkelephant.com, fetched 13 October 2026, HTTP 200), and corroborated word-for-word by a major US retailer’s listing for the same product (SKU P427421).

What is actually in Drunk Elephant Protini?
The front of the jar leads with peptides. The first nine ingredients are not peptides. In descending order of how much is in the jar, they are:
- Water — the solvent almost every water-based cream is built on.
- Dicaprylyl Carbonate — a light emollient ester, the kind of silicone alternative that gives a cream its slip.
- Glycerin — a humectant, one of the most reliable and least expensive moisturizing agents there is.
- Cetearyl Alcohol — a fatty alcohol that thickens and helps emulsify.
- Cetearyl Olivate and Sorbitan Olivate (5 and 6) — a pair of olive-derived emulsifiers that hold oil and water together.
- Sclerocarya Birrea Seed Oil — marula oil, a genuinely nice emollient with antioxidants.
- Bacillus/Folic Acid Ferment Extract — a fermented folic acid ingredient Drunk Elephant markets as a hero.
- Nymphaea Alba Root Extract — pygmy waterlily extract, the brand’s “stem cell” botanical.
None of this is a criticism. It is a perfectly competent moisturizer base — marula oil and a folic-acid ferment are more interesting than most. The point is only that these eight ingredients, not the peptides, make up the bulk of what you are applying. That is what “descending order of predominance” means, and it is worth knowing before we get to the part the name is selling.
Where do the peptides actually appear?
US cosmetic labels have to list ingredients in descending order of how much is present, down to one percent. Below one percent, a brand can list things in any order it likes. That rule is set out in 21 CFR 701.3 — subsection (a) requires descending order; subsection (f)(2) is the under-one-percent exemption. So ingredient position is not an exact percentage, but above that one-percent line it is a real signal of how much is in the jar.
Here is where Protini’s nine peptides sit:
| Position | INCI name | What it is |
|---|---|---|
| 10 | sh-Oligopeptide-1 | growth-factor-type peptide (EGF-style) — the first peptide in the list |
| 11 | sh-Oligopeptide-2 | growth-factor-type peptide (IGF-1-style) |
| 12 | sh-Polypeptide-1 | growth-factor-type peptide (bFGF-style) |
| 13 | sh-Polypeptide-9 | growth-factor-type peptide |
| 14 | sh-Polypeptide-11 | growth-factor-type peptide |
| 15 | Copper Palmitoyl Heptapeptide-14 | the copper peptide — a seven-amino-acid chain with a fatty-acid tail and copper |
| 16 | Heptapeptide-15 Palmitate | signal peptide |
| 17 | Palmitoyl Tetrapeptide-7 | signal peptide (often sold as Rigin) |
| 18 | Palmitoyl Tripeptide-1 | signal peptide — a palmitoylated GHK chain, without the copper |
The peptides occupy positions ten through eighteen. The one directly after them, at nineteen, is alanine — an individual amino acid. On most labels, the appearance of free amino acids marks the point where you have crossed below the one-percent line. The whole nine-peptide complex, in other words, almost certainly lives in the slice of the formula that sits under one percent combined. That is normal for peptides; they work at low concentrations. It is simply not what “polypeptide cream” implies to someone reading the front.
Is the copper peptide in Protini the one the research is about?
At position fifteen is Copper Palmitoyl Heptapeptide-14. When most people say “copper peptide” they mean something else: copper tripeptide-1, also written GHK-Cu (CAS 89030-95-5), a three-amino-acid chain bound to copper. GHK-Cu is the compound with the long history — a 2025 review of tripeptides in skin calls it one of the most-used peptides in the cosmetic industry and names copper tripeptide-1 as its INCI identity. Protini does not contain copper tripeptide-1. It contains a different, palmitoylated copper peptide.
That difference matters for how you read the research. A 2026 systematic review of GHK-Cu describes forty-plus years of pre-clinical work, then adds the honest part: the clinical evidence “remains thin and fragmented,” most trials are small, and the findings have not been validated in large human studies. So even for the best-studied copper peptide, the human evidence is promising rather than settled. For Copper Palmitoyl Heptapeptide-14 specifically, the published literature is thinner still — which is not the same as saying it does nothing, only that you should not read GHK-Cu’s forty-year file as if it belonged to this molecule. If you want the plain-English version of what a copper peptide even is, we wrote one (that is our site, Evil Goods).
What is everything below position eighteen?
The back half of the list is mostly supporting cast. Positions nineteen through twenty-nine are individual amino acids — alanine, arginine, glycine and the rest — which act as natural moisturizing factors and as the building blocks peptides are made from, but are not themselves peptides. Sodium hyaluronate, the much-hyped hydrating ingredient, sits all the way down at position thirty-two, well below that one-percent line.
Two preservatives sit near the very bottom: chlorphenesin at position fifty-two and phenoxyethanol at fifty-three. The Cosmetic Ingredient Review panel concluded chlorphenesin is safe at present practices of use and concentration. Alongside that, the patch-test literature carries a handful of case reports of allergic contact dermatitis from products containing it — the CIR report itself cites several. These are rare reactions at low rates, not a reason to avoid the ingredient, but worth knowing if your skin has flagged a preservative before. That is the honest shape of it: broadly safe by the review body’s assessment, with a small sensitization signal in the case reports.
So is Drunk Elephant Protini worth it?
If you like how it feels and it suits your skin, the position of an ingredient does not undo that — a good emollient base is a real thing to buy. What the label does tell you is that you are paying a peptide-cream price for a cream whose peptides sit below one percent, built on a base you could find in far cheaper moisturizers. Whether that trade is worth it is a judgement about your own skin and budget, not something the front of the jar settles for you. If you specifically want copper peptides, it is worth knowing which copper peptide you are buying and how thin the human evidence still is for any of them — including the one in our own Copper Peptide Blue Honey Serum, which uses copper tripeptide-1.
FAQ
- Where do the peptides start in Drunk Elephant Protini?
- At ingredient number ten, sh-Oligopeptide-1. The first nine ingredients are water, an emollient ester, glycerin, three emulsifiers, marula seed oil, a folic-acid ferment and a waterlily extract.
- What is sh-Oligopeptide-1?
- A synthetic growth-factor-style peptide (an EGF analog) used in skincare at low concentrations. It is the first of Protini’s nine-peptide complex.
- Is the copper peptide in Protini GHK-Cu?
- No. Protini contains Copper Palmitoyl Heptapeptide-14. GHK-Cu is copper tripeptide-1, a different molecule and the one most of the published research is conducted on.
- What does ingredient order tell you about a moisturizer?
- US rules require listing in descending order of amount down to one percent (21 CFR 701.3). So an ingredient’s position is a real signal of how much is present — above the one-percent line, at least. Below it, order no longer reflects quantity.
- Is chlorphenesin safe?
- The Cosmetic Ingredient Review panel concluded it is safe at the concentrations cosmetics use. A small number of allergic contact dermatitis case reports exist in the patch-test literature, which is a sensitization note rather than a general warning.
