Ingredient review
Cyclotetrapeptide-24 Aminocyclohexane Carboxylate
INCI: CYCLOTETRAPEPTIDE-24 AMINOCYCLOHEXANE CARBOXYLATE
A synthetic peptide that may help improve skin firmness and reduce fine lines, but more independent research is needed.
In plain English
This is a lab-made peptide, which is a small chain of amino acids (the building blocks of proteins). In skincare, peptides are used to signal skin cells to behave more youthfully. This particular peptide is designed to support the skin's natural structure, potentially making it feel firmer and look smoother over time. Think of it as a tiny messenger that tells your skin to keep its support system strong.

Quick decision guide
Useful, but context matters
Cyclotetrapeptide-24 Aminocyclohexane Carboxylate 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 Cyclotetrapeptide-24 Aminocyclohexane Carboxylate.
- 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 cyclic peptide (a ring-shaped chain of amino acids) modified with an aminocyclohexane carboxylate group to enhance stability and skin penetration. It is produced in a laboratory and not derived from natural sources.
How it works
It is believed to mimic natural peptide signals in the skin, encouraging fibroblasts (cells that produce collagen and elastin) to maintain the skin's extracellular matrix. By supporting this structural network, it may help reduce the appearance of fine lines and improve skin firmness over consistent use.
Pros
Gentle anti-aging support
This peptide is generally non-irritating and can be used daily as part of a preventive or corrective anti-aging routine without causing redness or peeling.
Stable in formulas
Its cyclic structure makes it more resistant to breaking down in skincare products, so it stays effective longer on the shelf compared to some linear peptides.
Cons and cautions
Subtle effects
Results are gradual and mild. You likely won't see dramatic changes overnight; it works best as a long-term maintenance ingredient rather than a quick fix.
Limited independent research
Most studies are conducted by the ingredient's manufacturer. More peer-reviewed, independent research would strengthen confidence in its efficacy.
Best for
- Adults looking for gentle anti-aging support
- Those with sensitive skin who tolerate peptides well
Use caution if
- Anyone with a known allergy to synthetic peptides (rare)
- Those expecting dramatic, instant results
Usage tips
Safety summary
Cyclotetrapeptide-24 aminocyclohexane carboxylate is considered safe for cosmetic use at typical concentrations. It has low irritation and comedogenic potential. As with any new ingredient, patch testing is recommended for those with very sensitive skin.
Research notes
Evidence for this specific peptide is primarily from manufacturer-sponsored studies showing improvements in skin firmness and wrinkle depth over 8-12 weeks. Independent peer-reviewed studies are limited, so the evidence level is moderate.
Common label clues
- Typical concentration
- 0.001% to 0.1%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. It is not a drug ingredient and is not intended to treat or prevent disease.
- Common uses
- Anti-aging serums, Eye creams, Facial moisturizers
- Environmental note
- As a synthetic peptide, its environmental impact is tied to the manufacturing process. It is not known to be bioaccumulative or toxic to aquatic life at typical cosmetic use levels.
Good to know
- Peptides work best when combined with other supportive ingredients like antioxidants (vitamin C, vitamin E) and moisturizers (hyaluronic acid, glycerin).
- This ingredient is often found in higher-end anti-aging products due to its synthetic production cost.
