Syn-Ake (Dipeptide Diaminobutyroyl Benzylamide Diacetate) and Argireline (Acetyl Hexapeptide-8) both aim at the look of expression lines, but they come from different makers, and each maker describes a different design in laboratory research. Syn-Ake is used at 1 to 4%, Argireline at 2 to 10%. The one direct comparison I found comes from Syn-Ake's own supplier literature, so read it with that in mind.
- Syn-Ake INCI: Glycerin, Aqua, Dipeptide Diaminobutyroyl Benzylamide Diacetate, made by dsm-firmenich.
- Argireline INCI: Acetyl Hexapeptide-8, formerly listed as Acetyl Hexapeptide-3, made by Lubrizol (Lipotec) (Lubrizol; CosIng).
- Use levels: Syn-Ake 1 to 4% (Univar), Argireline solution C 2 to 10% (Lubrizol).
- pH: Syn-Ake 4.5 to 5.5, stable from 3.0 to 5.5 (Pentapharm technical file). Argireline Amplified works from pH 4.0 to 8.0 (Lotioncrafter).
- Solubility: both water-soluble, both added at cool-down below 40°C (Lotioncrafter).
What is the difference between Syn-Ake and Argireline?
Their makers describe different targets. Lubrizol says Argireline destabilizes the SNARE complex, a protein assembly involved in cell signaling (Lubrizol). dsm-firmenich describes Syn-Ake, from laboratory work, as acting at the acetylcholine receptor. The maker says its sequence is modeled on Waglerin-1, a peptide found in temple viper venom; Syn-Ake itself is a lab-made amino acid derivative, not venom (dsm-firmenich). The Pentapharm technical file describes the receptor binding site as an assumption, not a confirmed finding.
All of this comes from laboratory models. On skin, both are aimed at the look of forehead lines and crow's feet.
Is Syn-Ake better than Argireline?
The only head-to-head I found is supplier-run. In a Syn-Ake technical document issued by Pentapharm, 45 volunteers applied Syn-Ake 4%, a placebo or 10% Acetyl Hexapeptide-3 (Argireline under its older name) twice daily for 28 days. Pentapharm reports that Syn-Ake gave the larger change in forehead smoothness and line depth (Pentapharm). The chart in that file does not clearly label which percentage belongs to which product, so I am not quoting a number from it.
dsm-firmenich also describes a 100-volunteer study, 25 per group, comparing Syn-Ake 4% to placebo twice daily for 4 weeks, without listing the numeric results on the page (dsm-firmenich).
Argireline has more outside studies, and they are mixed. Wang and colleagues (2013) reported 48.9% subjective efficacy against 0% for placebo in 60 adults over 4 weeks (study record). Henseler (2023) found no significant difference between the Argireline side and the control side in a 19-woman, split-face, double-blind study (Henseler).
One more thing to know: the "up to 52%" Syn-Ake figure you see online comes from a single volunteer's forehead measurement in the Pentapharm file. One person is a case, not a result.
Syn-Ake vs Argireline side by side
| Syn-Ake | Argireline | |
|---|---|---|
| INCI name | Dipeptide Diaminobutyroyl Benzylamide Diacetate | Acetyl Hexapeptide-8 |
| What it is | Small amino acid derivative in glycerin and water, dsm-firmenich | Six-amino-acid sequence, Lubrizol (Lipotec) |
| How it works (maker description, lab research) | Acts at the acetylcholine receptor | Destabilizes the SNARE complex |
| Typical usage rate | 1 to 4% | 2 to 10% (solution C), 2 to 5% (Amplified) |
| pH working range | Stable 3.0 to 5.5; supplied at 4.5 to 5.5 | 4.0 to 8.0 in formula (Amplified grade) |
| Solubility | Water; compatible with up to 50% ethanol | Water (an oil-soluble YOUth grade also exists) |
| Pairs well with | Argireline and Snap-8 by formulation practice | Pentapeptide-18 (Leuphasyl), the pairing with published data |
| Keep apart from | Formula pH above 5.5, outside its stated stability range; heat above 40°C | Heat above 40°C during blending |
The pH detail most guides miss
Syn-Ake has the narrower window. The technical file lists stability from pH 3.0 to 5.5 (Pentapharm). Argireline Amplified tolerates pH 4.0 to 8.0 (Lotioncrafter). If you are blending your own, check your base's pH before you add Syn-Ake. If it runs above 5.5, Argireline is the easier fit.
Which one suits you?
- Choose Syn-Ake if you want a lower use level, a different target step, and your base sits at pH 5.5 or below.
- Choose Argireline if you want more independent human data, a wider pH window, or an oil-soluble grade.
- Use both if you want two target steps in one serum. Keep the base at pH 5.5 or below so Syn-Ake stays in its range. I found no published study on this pair, so this is formulation practice.
How to use Syn-Ake and Argireline in a routine
Our Argireline Acetyl Hexapeptide-8 serum booster is a raw solution you add to a water-based serum, lotion or cream at 2 to 10%. Do not apply it undiluted.
- Refrigerate boosters on arrival.
- Check your base pH if you plan to add Syn-Ake.
- Add Argireline at 9 drops per 1% per fluid ounce of base. For 5% in 1 oz, that is 45 drops. Keep Syn-Ake inside 1 to 4%.
- Apply the blend to the forehead, between the brows and around the eyes, morning and night.
- Take same-light photos at week 0 and week 4, the length of most studies above.

Frequently asked questions
Is Syn-Ake made from snake venom?
No. dsm-firmenich says Syn-Ake copies the functional amino acid sequence of Waglerin-1, a peptide found in temple viper venom. The ingredient itself is a small lab-made amino acid derivative sold in glycerin and water. Its INCI name, Dipeptide Diaminobutyroyl Benzylamide Diacetate, is what you will see on a label.
What percentage of Syn-Ake should a product have?
Distributors list a 1 to 4% use level for Syn-Ake, and the supplier studies used 4%. That percentage refers to the solution as supplied, not pure ingredient. A product that states its Syn-Ake percentage lets you check that it sits inside the range the supplier studied.
Can I use Syn-Ake and Argireline together?
Yes. Both are water-soluble and both go in below 40°C. The main catch is pH: Syn-Ake is stable from pH 3.0 to 5.5, so the base needs to stay in that range. I found no published study on the two together, so combining them is formulation practice, not a studied result.
Which works faster, Syn-Ake or Argireline?
No independent study has timed them against each other. The supplier comparison ran 28 days, and the Argireline studies above ran 4 weeks. Lubrizol claims a change in the look of lines within one week at 2% Argireline, without listing study details. Judge your own results at the four-week mark.
