Ingredient review
Copper Aminoacetylamino Imidazolyl Propanoate
INCI: COPPER AMINOACETYLAMINO IMIDAZOLYL PROPANOATE
A gentle copper-peptide ingredient that supports skin repair and fights oxidative stress, but research is still emerging.
In plain English
This is a man-made molecule that combines copper with a small protein fragment (a peptide). In skincare, it helps calm inflammation, protect skin from environmental damage, and support the skin's natural repair processes. Think of it as a helper that tells your skin cells to work more efficiently at healing and defending themselves.

Quick decision guide
Useful, but context matters
Copper Aminoacetylamino Imidazolyl Propanoate 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 Copper Aminoacetylamino Imidazolyl Propanoate.
- 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 compound where copper is bound to a modified amino acid and an imidazole ring, designed to deliver copper to skin cells in a stable, bioavailable form.
How it works
Once applied, the copper ion is slowly released and can act as a cofactor for enzymes involved in collagen production and antioxidant defense. The peptide portion may also signal skin cells to reduce inflammation and increase repair activity.
Pros
Gentle on skin
Irritation risk is low, making it suitable for sensitive skin types that may react to stronger actives.
Supports repair
Copper delivery may aid the skin's natural healing processes, which can be helpful after mild irritation or environmental exposure.
Cons and cautions
Limited research
Compared to classic copper peptides like Copper Tripeptide-1, this specific compound has fewer published studies backing its efficacy.
Higher price point
Synthetic peptide ingredients are typically more expensive to produce, which can increase product cost.
Best for
- Anyone looking for a gentle antioxidant to support skin repair
- People with sensitive or reactive skin who want a low-irritation peptide option
Use caution if
- Those with known copper allergy or Wilson's disease should consult a doctor before use
Usage tips
Safety summary
Generally recognized as safe for topical cosmetic use at typical concentrations. No significant irritation or sensitization has been reported in available data. As with any copper compound, individuals with copper metabolism disorders should exercise caution.
Research notes
Evidence is moderate and largely extrapolated from studies on other copper peptides. Direct clinical trials on this specific molecule are limited, but its mechanism is well understood based on copper biochemistry.
Common label clues
- Typical concentration
- 0.1% to 1% in leave-on products
- Regulatory status
- Approved for cosmetic use in the EU, US, and other major markets as a skin-conditioning agent.
- Common uses
- Anti-aging serums, Eye creams, Repair moisturizers
- Environmental note
- Synthetic production reduces reliance on animal-derived or plant-extracted peptides, but the environmental impact of manufacturing is not well documented.
Good to know
- This ingredient is often found in serums and treatments targeting aging or post-procedure recovery.
- It is not the same as Copper Tripeptide-1, though both deliver copper to the skin.
