Dermaxyl vs Matrixyl: Two Matrikine Peptides Compared

Dermaxyl and Matrixyl are both Sederma peptide actives, but they are built for different phases of a formula. Dermaxyl is an oil-soluble waxy complex that pairs a ceramide with an elastin-derived peptide, Palmitoyl Hexapeptide-12, and is melted into the oil phase at about 85 °C at a recommended 2%. Matrixyl is a water-based gel solution of Palmitoyl Pentapeptide-4, a collagen-fragment peptide that can be added cold, so the real choice is less about which one is stronger and more about which one fits your base.

The comparison is also confusing for a simple historical reason. For years both families carried the same vague ingredient name, Palmitoyl Oligopeptide, on their datasheets, so two very different peptides looked identical on a label. This guide untangles the names, compares what each manufacturer has actually published, and shows where each one makes sense in a cream, serum or foundation.

Why the Names Get Mixed Up

Sederma, now part of Croda Beauty Actives, gave several of its peptides the generic INCI name Palmitoyl Oligopeptide before the international nomenclature committee assigned specific names. Older Dermaxyl sheets list Palmitoyl Oligopeptide for the peptide Pal-Val-Gly-Val-Ala-Pro-Gly. Older Matrixyl 3000 sheets list the same Palmitoyl Oligopeptide for a completely different molecule, Pal-Gly-His-Lys. Today the first is called Palmitoyl Hexapeptide-12 and the second Palmitoyl Tripeptide-1.

The original Matrixyl adds a third name to the puzzle. Its peptide, Pal-Lys-Thr-Thr-Lys-Ser, was once listed as Palmitoyl Pentapeptide-3 and is now Palmitoyl Pentapeptide-4, often shortened to Pal-KTTKS. So when a forum post or an old supplier sheet says Palmitoyl Oligopeptide, you cannot tell which peptide it means without the trade name or the amino acid sequence. When you buy, ask for the current INCI and the sequence, and print the current INCI on your own label.

Dermaxyl: Ceramide Plus an Elastin Fragment

Dermaxyl is not a single peptide but a ready complex. The current Croda INCI reads C12-15 Alkyl Benzoate (and) Tribehenin (and) Ceramide NG (and) PEG-10 Phytosterol (and) Palmitoyl Hexapeptide-12. Older documents list Ceramide 2 and PEG-10 Rapeseed Sterol in the same positions, which reflects naming updates rather than a new concept. The emollient ester and the tribehenin wax carry the ceramide and the peptide, which is why the material is a soft paste and not a powder or a gel.

The peptide part, VGVAPG, is a repeating sequence found in elastin that Sederma calls its spring fragment. In manufacturer cell work, the palmitoylated version attracted fibroblasts and raised the gene expression of a signaling protein called GCP-2. The ceramide part is the barrier story: ceramides are the lipids that hold the outer layer of skin together, and Sederma positions Dermaxyl for skin that looks dry and lined at the same time.

Its published panel test is unusual because it was run in makeup. Twenty-four women aged 42 to 66 used a liquid foundation with 2% Dermaxyl daily for 56 days, and the profilometry results reported a mean reduction of 13.7% in the volume of the main wrinkle and 10.1% in its depth. Larger percentages appear in marketing material, but those are the best individual results, not the average, and the study had no placebo arm in the summary sheet.

Matrixyl: A Collagen Fragment in a Water Gel

The original Matrixyl solution has the INCI Glycerin (and) Water (and) Butylene Glycol (and) Carbomer (and) Polysorbate 20 (and) Palmitoyl Pentapeptide-4. The peptide content in that solution is tiny, about 100 parts per million, and the rest is a glycerin gel that disperses easily in water. Croda describes it as suitable for cold processes, so it can be stirred into a serum or added during the cool-down of an emulsion without heating.

KTTKS is a fragment of type I procollagen, and adding a palmitic acid chain makes it more compatible with the skin surface. Unlike most raw material peptides, this one has independent data. A study by Robinson and colleagues in the International Journal of Cosmetic Science in 2005 followed 93 women for 12 weeks in a split-face design and reported better-looking fine lines and wrinkles on the side that used a moisturizer with palmitoyl pentapeptide than on the placebo side. That paper is still the most cited human evidence for any signal peptide in cosmetics.

Matrixyl 3000 is a different product that people often lump together with the original. It combines Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7 in a similar glycerin and carbomer gel, and current Sederma sheets recommend 3%, while older sheets gave 3 to 8%. If you want to read about that pair specifically, it is sold on our site as Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7 Liquid, and the GHK half alone as Palmitoyl Tripeptide-1 Solution.

Dermaxyl vs Matrixyl Side by Side

Solubility and Process

This is the deciding difference. Dermaxyl is oil-soluble, and Sederma instructs formulators to melt it at 85 °C right before use and add it to the hot oil phase while the emulsion forms. It cannot go into a clear water serum. Matrixyl is water-dispersible and goes in cold, so it suits gels, watery serums, toners and the cool-down phase of any cream. If your product has no oil phase, the decision is already made.

Use Level and Active Content

Dermaxyl is recommended at 2% of the formula, and that 2% brings the ceramide, the peptide and the emollient carriers together. Matrixyl solutions are dosed by the solution, not by the peptide, so a few percent of gel delivers only a few parts per million of Pal-KTTKS. When you work from pure powder, such as our Palmitoyl Pentapeptide-4 Powder, the dose is set by the supplier certificate for your lot, and you will be weighing milligrams, not grams.

Product Formats

Dermaxyl was tested in foundation and is listed by Croda for face care, eye contour, lip care and color cosmetics, which makes it a natural fit for anhydrous balms, lipsticks, cushion foundations and rich creams. Matrixyl is the more universal choice for serums, eye gels and light lotions. Many finished products on the market use both, putting the oil-soluble complex in the emulsion and the water-soluble peptide in the cool-down.

Evidence and Claims

Matrixyl has the stronger public record because of the independent 2005 study, while Dermaxyl's human data comes from the manufacturer alone. Neither set of numbers belongs on a finished product unless your own product was tested. What both support is cosmetic language about the look of fine lines, smoother-feeling skin and a more comfortable, less dry feel.

How to Use Them Together

A combined cream is straightforward. Melt Dermaxyl at 85 °C, add it to an oil phase that is already hot, emulsify into the heated water phase, then cool. Below 40 °C add the Matrixyl solution or a pre-dissolved stock of Pal-KTTKS powder along with humectants such as glycerin and a hyaluronic acid liquid. A final pH between about 5 and 6.5 suits both peptides and most emulsifiers. Keep strong acids, oxidizers and high electrolyte loads out of the formula, and keep copper peptides in a separate product.

If you want the barrier side without a branded complex, a single ceramide such as Ceramide NP in the oil phase plus a water-soluble peptide in the cool-down gives a similar structure, although Ceramide NP is a different ceramide from the one in Dermaxyl and needs its own melting step. For a full multi-peptide serum, our peptide serum recipe for wrinkles shows how signal peptides share one water phase, and the cosmetic peptide powders guide covers weighing and pre-dissolving milligram amounts.

Choosing Between Them

Pick Dermaxyl when the product is a cream, balm, stick or foundation, when dryness and lines are both part of the brief, and when you are already running a hot process. Pick Matrixyl or neat Pal-KTTKS when the product is a water-based serum or gel, when you need a cold process, or when you want the peptide with the longest public evidence trail. Choose Palmitoyl Tripeptide-1 with Palmitoyl Tetrapeptide-7 when you want the matrikine pair that Sederma launched as the successor to the original.

Buying neat peptides instead of branded solutions gives you control over the dose and a shorter label, and our peptide powders section lists Pal-KTTKS next to newer options such as Palmitoyl Tripeptide-38 Powder. Ready liquids, including the matrikine pair, sit in the peptide solutions section. Whatever you choose, run a four-week stability check at room temperature, at 40 °C and in the refrigerator, and a preservative challenge test before launch.
