Dipeptide Diaminobutyroyl Benzylamide Diacetate

INCI: DIPEPTIDE DIAMINOBUTYROYL BENZYLAMIDE DIACETATE

A synthetic peptide that temporarily softens expression wrinkles by calming muscle contractions, similar to a milder, topical version of neuromodulators.

beautyskincarepeptide

In plain English

This ingredient is a lab-made peptide that works like a very gentle, temporary muscle relaxant for your skin. When applied in a cream or serum, it can help soften the look of frown lines and crow's feet by reducing the intensity of facial muscle movements. It's often called 'Syn-Ake' because it mimics a compound found in temple viper venom, but it's completely safe and non-toxic.

Quick decision guide

Useful, but context matters

Dipeptide Diaminobutyroyl Benzylamide Diacetate is generally a lower-concern ingredient when the full formula suits your skin.

Plain-English read

Treat this as a practical screening step before you compare products that contain this ingredient.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Dipeptide Diaminobutyroyl Benzylamide Diacetate.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.

Score terms in plain English

Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

A synthetic tripeptide (a short chain of amino acids) that mimics the action of waglerin-1, a neuropeptide from the venom of the temple viper. It is designed to temporarily inhibit muscle contraction at the neuromuscular junction.

How it works

It binds to the same receptors on muscle cells that are normally activated by nerve signals. By competing with natural neurotransmitters, it reduces the strength of muscle contractions, which in turn softens the appearance of dynamic wrinkles caused by repeated facial expressions.

Pros

Mimics a potent natural peptide

It is inspired by a snake venom peptide but is completely safe and non-toxic, offering a novel approach to wrinkle reduction.

Targets expression lines

Specifically works on dynamic wrinkles caused by muscle movement, making it a good option for frown lines and crow's feet.

Cons and cautions

Temporary results

The effects wear off within hours to days after stopping use, so you need to apply it consistently to see ongoing benefits.

Limited depth of effect

It cannot penetrate as deeply as injectable treatments, so it is best for superficial lines rather than deep-set wrinkles.

Best for

  • People looking for a topical anti-aging option to soften fine lines
  • Those who prefer non-invasive skincare over injectables

Use caution if

  • Individuals with very deep static wrinkles may not see significant improvement

Usage tips

Apply to clean, dry skin before heavier creams or oils to maximize absorption.
Use consistently twice daily for at least 4–8 weeks to see visible improvement.

Safety summary

Considered safe for topical use at typical cosmetic concentrations. Rare reports of mild irritation or allergic reaction. Avoid contact with eyes and broken skin.

Research notes

Clinical studies show a statistically significant reduction in wrinkle depth and surface area after 28 days of use, though results vary by individual. More independent research is needed to compare efficacy across different peptide formulations.

Common label clues

Typical concentration
0.001% to 0.01%
Regulatory status
Approved as a cosmetic ingredient in the EU, US, and many other regions. Not classified as a drug.
Common uses
Anti-aging serums, Eye creams, Facial treatments
Environmental note
Synthesized in a lab, so it does not involve animal harvesting and has a relatively low environmental footprint compared to natural extracts.

Good to know

  • Often listed under trade names like Syn-Ake or SYN®-AKE in ingredient lists.
  • It is a water-soluble peptide, so it works best in water-based serums rather than oil-based products.
