Ingredient review
Tetradecyl Aminobutyroylvalylaminobutyric Urea Trifluoroacetate
INCI: TETRADECYL AMINOBUTYROYLVALYLAMINOBUTYRIC UREA TRIFLUOROACETATE
A synthetic peptide that mimics the effects of certain neuropeptides to soften expression lines, but results are subtle and temporary.
In plain English
This is a lab-made peptide (a small chain of amino acids) designed to relax facial muscles, similar to how some wrinkle treatments work, but much milder. When applied to the skin, it can temporarily soften the look of fine lines, especially around the eyes and forehead. It is not a permanent fix and works best with consistent use over time.

Quick decision guide
Useful, but context matters
Tetradecyl Aminobutyroylvalylaminobutyric Urea Trifluoroacetate 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.
- Step 1Start with the score, then check the irritation and clogging risk before judging Tetradecyl Aminobutyroylvalylaminobutyric Urea Trifluoroacetate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- 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
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic peptide compound that includes a fatty acid chain (tetradecyl) attached to a sequence of amino acids, designed to penetrate the skin and mimic the action of natural neuropeptides.
How it works
It is thought to work by inhibiting the release of certain neurotransmitters at the neuromuscular junction, which temporarily reduces muscle contractions that cause expression lines. This leads to a visible smoothing of wrinkles, similar to a very mild, topical version of neuromodulators like Botox, but without injections.
Pros
Non-invasive wrinkle softening
Offers a topical option to reduce the look of fine lines without needles or downtime, making it accessible for daily use.
Generally well-tolerated
At typical low concentrations, it rarely causes irritation, making it suitable for most skin types, including sensitive skin.
Cons and cautions
Subtle and temporary results
The smoothing effect is mild compared to professional treatments, and it fades quickly if you stop using the product.
Limited independent research
Most studies are small or funded by manufacturers, so the evidence for its efficacy is not as robust as for some other anti-aging ingredients.
Best for
- Adults looking for a gentle, non-invasive way to soften expression lines
- Those who want to supplement their anti-aging routine with a peptide serum
Use caution if
- People with very sensitive skin or known allergies to synthetic peptides
- Those expecting dramatic, immediate results similar to injectable treatments
Usage tips
Safety summary
Considered safe for topical use at typical concentrations. Rare reports of mild irritation or allergic reactions. Avoid if you have a known sensitivity to peptides.
Research notes
Clinical studies show modest improvement in wrinkle depth and skin smoothness after 4-8 weeks of use. Most research is manufacturer-sponsored, so independent confirmation is limited.
Common label clues
- Typical concentration
- 0.001% to 0.1%
- Regulatory status
- Approved for cosmetic use in the EU, US, and other major markets as a skin conditioning agent. Not regulated as a drug.
- Common uses
- Anti-aging serums, Eye creams, Wrinkle treatments
- Environmental note
- As a synthetic peptide, its environmental impact is minimal compared to some natural extracts, but manufacturing involves chemical synthesis.
Good to know
- This ingredient is often listed under trade names like 'Syn-Ake' or similar peptide complexes.
- It is not a substitute for sunscreen or other proven anti-aging measures like retinoids.
