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.

beautyskincareantioxidant

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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Copper Aminoacetylamino Imidazolyl Propanoate.
  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 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

Apply after cleansing and before heavier creams to allow absorption.
Store products containing this ingredient away from direct sunlight and heat to maintain stability.

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.
