Matrixyl vs SYN-AKE
Comprehensive side-by-side comparison of mechanisms, dosing, side effects, and research
Also: Palmitoyl Pentapeptide-4, Pal-KTTKS
Matrixyl is the trade name (Sederma) for palmitoyl pentapeptide-4, also written Pal-KTTKS, a collagen-fragment peptide attached to a fatty acid so it can cross skin. Unlike Botox-mimic peptides, it does not touch muscle: it signals skin cells to rebuild collagen, so it is aimed at fine lines, firmness and skin texture rather than expression wrinkles. It is a cosmetic ingredient with one of the better-documented topical studies in the peptide space, though far short of drug-grade proof.
Also: Dipeptide diaminobutyroyl benzylamide diacetate, SYN-AKE
SYN-AKE is DSM's trade name for dipeptide diaminobutyroyl benzylamide diacetate, the 'snake venom' peptide in a lot of anti-wrinkle creams. The marketing says it mimics Waglerin-1, a toxin from the temple viper. To be clear: there is no venom in it. It is a tiny synthetic molecule, and the evidence that it relaxes wrinkles comes almost entirely from the manufacturer.
Key Comparison Insights
- Both peptides belong to the Skin & Hair category, suggesting similar primary applications.
Detailed Comparison

|---|---|---|
| Category | Skin & Hair | Skin & Hair |
| FDA Status | Not FDA Approved | Not FDA Approved |
| Clinical Status | Pre I II III IV FDA | Pre I II III IV FDA |
| Mechanism of Action | KTTKS is a five-amino-acid piece of type I collagen. When collagen breaks down, fragments like this are released, and the skin reads them as a signal that the matrix needs repair, which prompts fibroblasts to make more collagen and other support proteins, a process called matrikine signaling. Matrixyl essentially feeds the skin that repair signal on purpose. The palmitoyl (fatty acid) tail is bolted on to make the otherwise water-loving peptide lipophilic enough to penetrate the outer skin layer, which is the part that actually lets a topical work. | DSM describes SYN-AKE as a reversible blocker of the muscle-type nicotinic acetylcholine receptor, the receptor on muscle that acetylcholine opens to make it contract. Block it, the theory goes, and facial muscles relax a little. That is the real mechanism of Waglerin-1, a 22-amino-acid viper toxin that independent research shows selectively blocks the adult form of this receptor. SYN-AKE itself is a much smaller molecule (beta-alanine, proline and diaminobutyric acid with a benzylamide end, under 500 daltons), and the claim that it does the same thing comes from the manufacturer's own cell test, where innervated muscle cells contracted less. Even DSM's older material calls the binding 'probable'. As with Argireline, there is no independent proof that a cream gets enough of it to facial muscle to matter. |

| Research Summary | Matrixyl has the kind of human data most cosmetic peptides lack. The pivotal Robinson 2005 study in the International Journal of Cosmetic Science was a 12-week, double-blind, placebo-controlled, split-face trial in 93 women aged 35 to 55, comparing a moisturizer with 3 ppm Pal-KTTKS against the same moisturizer alone, and it found significant reductions in wrinkles and fine lines on the peptide side, with good tolerability. Cell and lab studies support the mechanism, showing increased synthesis of collagen I and IV and fibronectin. The frequently quoted figures like 117 percent collagen increase or 68 percent wrinkle reduction come largely from manufacturer in vitro and formulation data, so treat the exact percentages skeptically even though the direction of effect is real. Overall this is a well-tolerated peptide with genuine, if modest, controlled human evidence for texture and fine lines, and it does not require injection. It will not erase deep dynamic wrinkles the way muscle-targeting treatments aim to. | DSM's brochure reports two pieces of data. In vitro, 0.5 mM of the peptide cut the contraction frequency of innervated muscle cells. In vivo, a 4% SYN-AKE cream was compared with placebo in 15 volunteers per group (aged 40-60), applied twice daily for 28 days, with reductions of roughly 15-21% in skin roughness and wrinkle measures and a headline of 'up to 52%' wrinkle reduction in the best responders. A US patent also describes a double-blind study in 59 women aged 40-55 reporting smaller pores and less shine after 28 days, but that is a patent filing, not a peer-reviewed paper. A 2020 review of cosmetic peptides states plainly that there are no scientific papers describing clinical studies of this peptide, so the efficacy story rests on company data. Bottom line: a well-tolerated cosmetic ingredient with a catchy story. The venom angle is marketing, and the 'up to 52%' number is a best case from a 15-person company study, not a typical result. |
Frequently Asked Questions: Matrixyl vs SYN-AKE
What is the difference between Matrixyl and SYN-AKE?
Matrixyl is a skin & hair peptide that matrixyl is the trade name (sederma) for palmitoyl pentapeptide-4, also written pal-kttks, a collagen-fragment peptide attached to a fatty acid so it can cross skin. unlike botox-mimic peptides, it does not touch muscle: it signals skin cells to rebuild collagen, so it is aimed at fine lines, firmness and skin texture rather than expression wrinkles. it is a cosmetic ingredient with one of the better-documented topical studies in the peptide space, though far short of drug-grade proof. SYN-AKE is a skin & hair peptide that syn-ake is dsm's trade name for dipeptide diaminobutyroyl benzylamide diacetate, the 'snake venom' peptide in a lot of anti-wrinkle creams. the marketing says it mimics waglerin-1, a toxin from the temple viper. to be clear: there is no venom in it. it is a tiny synthetic molecule, and the evidence that it relaxes wrinkles comes almost entirely from the manufacturer. The main differences lie in their mechanisms of action and clinical applications.
Which is better, Matrixyl or SYN-AKE?
Neither is universally "better" - the choice depends on your specific goals. Matrixyl is typically used for skin & hair purposes, while SYN-AKE is used for skin & hair. Always consult with a healthcare provider to determine which may be appropriate for your situation.
Can Matrixyl and SYN-AKE be used together?
Some peptide protocols combine multiple compounds for synergistic effects. However, using Matrixyl and SYN-AKE together should only be considered under medical supervision, as both compounds have their own side effect profiles and potential interactions. Research on their combined use may be limited.
