Ingredient review
Pentasodium Tetracarboxymethyl Hexanoyl Dipeptide-12
INCI: Pentasodium Tetracarboxymethyl Hexanoyl Dipeptide-12
A synthetic peptide that may help reduce fine lines and support skin firmness, but more human studies are needed.
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 reduce the appearance of wrinkles and improve skin firmness. Think of it as a messenger that tells your skin to act younger.

Quick decision guide
Useful, but context matters
Pentasodium Tetracarboxymethyl Hexanoyl Dipeptide-12 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 Pentasodium Tetracarboxymethyl Hexanoyl Dipeptide-12.
- 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 peptide ingredient designed to mimic natural signaling molecules in the skin. It is water-soluble and often included in anti-aging formulations.
How it works
It is believed to bind to specific receptors on skin cells, triggering a cascade that boosts collagen production and reduces the breakdown of existing collagen. This can lead to firmer, smoother skin over time.
Pros
Targeted anti-aging
Specifically designed to support collagen, which can help reduce fine lines and improve skin texture over weeks of use.
Low irritation potential
Generally non-irritating and non-comedogenic, making it suitable for most skin types, including sensitive skin.
Cons and cautions
Modest evidence
While promising, much of the evidence comes from lab studies or small trials; larger human studies are still limited.
Cost
Peptide-based products tend to be more expensive than simpler anti-aging ingredients like glycerin or niacinamide.
Best for
- People looking for anti-aging benefits
- Those with fine lines and loss of firmness
Use caution if
- Those with very sensitive skin who react to many peptides
- Pregnant or nursing individuals should consult a doctor
Usage tips
Safety summary
Considered safe for topical use at typical concentrations. Rare reports of mild irritation in very sensitive individuals. No known serious safety concerns.
Research notes
In vitro and some small clinical studies suggest it can stimulate collagen synthesis and reduce wrinkle depth. However, large-scale, peer-reviewed human trials are sparse, so evidence is moderate.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Approved for cosmetic use in the US, EU, and other major markets. Not classified as a drug ingredient.
- Common uses
- Anti-aging serums, Eye creams, Moisturizers
- Environmental note
- Synthetic peptides are produced in labs, which reduces the need for natural resource extraction, but their manufacturing may involve chemical processes.
Good to know
- This peptide is often combined with other anti-aging ingredients like retinol or vitamin C for enhanced effects.
- It is water-soluble, so it works well in serums and lightweight gels.
