Ingredient review
Tranexamoyl Dipeptide-22
INCI: Tranexamoyl Dipeptide-22
A gentle peptide that may help calm redness and support skin barrier comfort, though human studies are still limited.
In plain English
Tranexamoyl Dipeptide-22 is a lab-made peptide that combines a modified form of tranexamic acid (an ingredient known for helping with discoloration) with a short chain of amino acids. In skincare, it is used to help soothe visible skin reactivity and reduce the appearance of redness. Think of it as a calming signal for your skin cells, telling them to settle down when they might otherwise become irritated. It is not a drug and does not treat medical conditions like rosacea, but it may offer a gentle option for those with easily bothered skin.

Quick decision guide
Useful, but context matters
Tranexamoyl Dipeptide-22 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 Tranexamoyl Dipeptide-22.
- 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 consisting of a tranexamic acid derivative linked to a dipeptide (two amino acids). It is designed to be more stable and targeted than using tranexamic acid alone.
How it works
It is thought to work by interfering with certain inflammatory signaling pathways in skin cells, reducing the release of compounds that cause redness and irritation. It may also help strengthen the skin barrier by supporting the production of structural proteins.
Pros
Gentle calming action
Tranexamoyl Dipeptide-22 is designed to reduce visible redness without the irritation that some stronger active ingredients can cause, making it suitable for sensitive skin.
Barrier support potential
Early research suggests it may help reinforce the skin barrier, which can improve overall skin resilience and comfort over time.
Cons and cautions
Limited evidence
Most of the supporting data comes from lab studies or small trials, so the real-world benefits for a broad population are not yet fully established.
Premium price point
As a synthetic peptide, it is more expensive to produce than simpler soothing agents like niacinamide or green tea extract, which may increase product cost.
Best for
- People with occasional redness or flushing
- Those with sensitive or reactive skin looking for a gentle soothing ingredient
Use caution if
- Anyone with a known allergy to peptides or tranexamic acid derivatives
Usage tips
Safety summary
Tranexamoyl Dipeptide-22 is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and comedogenic potential. However, long-term safety data in large human populations is still emerging.
Research notes
Early in vitro and small-scale human studies suggest anti-inflammatory and barrier-supporting effects. More robust clinical trials are needed to confirm efficacy and compare with established soothing ingredients.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Generally recognized as a cosmetic ingredient in the US and EU; not classified as a drug. No specific regulatory warnings.
