Ingredient review
Sodium Formylhippurate Trifluoroacetylisobutyl Dipeptide-42 Amide
INCI: Sodium Formylhippurate Trifluoroacetylisobutyl Dipeptide-42 Amide
A synthetic peptide that may help reduce fine lines by supporting collagen, but research is still limited and it's less studied than more common peptides.
In plain English
This is a lab-made peptide, which is a small chain of amino acids (the building blocks of protein). In skincare, peptides are used to signal skin cells to produce more collagen and elastin, which can help smooth wrinkles and firm the skin. This particular peptide has a modified structure to make it more stable and effective on skin, but it's a newer ingredient with less independent research compared to classics like Matrixyl or copper peptides.

Quick decision guide
Useful, but context matters
Sodium Formylhippurate Trifluoroacetylisobutyl Dipeptide-42 Amide 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 Sodium Formylhippurate Trifluoroacetylisobutyl Dipeptide-42 Amide.
- 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
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A synthetic peptide ingredient with a modified amino acid sequence designed to mimic natural signaling molecules that stimulate collagen production in the skin.
How it works
When applied topically, the peptide is thought to bind to receptors on skin cells, triggering a cascade of signals that encourage fibroblasts to produce more collagen and elastin. This can help improve skin firmness and reduce the appearance of fine lines over time.
Pros
Gentle on skin
Low irritation and comedogenic risk make it suitable for sensitive skin types, unlike some stronger anti-aging actives.
Targets collagen production
Works at a cellular level to support the skin's natural collagen synthesis, which can help with firmness over time.
Cons and cautions
Limited research
This specific peptide has fewer peer-reviewed studies compared to well-established peptides, so its efficacy is less certain.
Subtle results
Improvements in fine lines and firmness are gradual and may not be noticeable for several months of consistent use.
Best for
- Adults looking for a gentle anti-aging ingredient
- Those with sensitive skin who want to avoid stronger actives like retinol
Use caution if
- Anyone seeking immediate or dramatic results
- Those on a tight budget, as peptide products tend to be pricier
Usage tips
Safety summary
Generally considered safe for topical use at typical concentrations. Low irritation and comedogenic risk. No significant safety concerns reported in cosmetic use, but long-term data on this specific peptide is limited.
Research notes
Peptides as a class have moderate evidence for anti-aging benefits, but this specific derivative has limited published research. Most evidence comes from manufacturer studies and analogy to similar peptides.
Common label clues
- Typical concentration
- Typically used at 0.1% to 2% in leave-on products
- Regulatory status
- Approved as a cosmetic ingredient in the EU, US, and other major markets; not classified as a drug.
- Common uses
- Anti-aging serums, Eye creams, Facial moisturizers
- Environmental note
- Synthetic peptides are produced in labs, which reduces the need for natural resource extraction, but their manufacturing process may involve chemical solvents.
Good to know
- Peptides work best when combined with other supportive ingredients like niacinamide, ceramides, and antioxidants.
- This ingredient is often found in higher-end anti-aging formulations due to its specialized synthesis.
