Ingredient review
Heptasodium Hexacarboxymethyl Dipeptide-12
INCI: HEPTASODIUM HEXACARBOXYMETHYL DIPEPTIDE-12
A synthetic peptide that may help reduce fine lines and improve skin firmness, but research is still emerging.
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 produce more collagen and elastin, which can help reduce the appearance of wrinkles and make skin feel firmer. Heptasodium Hexacarboxymethyl Dipeptide-12 is a specific type of peptide that is designed to be stable and effective in formulas.

Quick decision guide
Useful, but context matters
Heptasodium Hexacarboxymethyl 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 Heptasodium Hexacarboxymethyl 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
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A synthetic peptide, specifically a dipeptide (two amino acids linked together) modified with carboxymethyl groups and neutralized with sodium to improve stability and water solubility.
How it works
It is thought to work by mimicking natural peptide signals in the skin, encouraging fibroblasts (cells that produce collagen) to increase collagen synthesis. This can help improve skin firmness and reduce the appearance of fine lines and wrinkles over time.
Pros
Gentle on skin
Low irritation and comedogenic risk, making it suitable for sensitive skin types.
Supports collagen production
May help stimulate collagen synthesis, which can improve skin firmness and reduce fine lines over time.
Cons and cautions
Limited research
There are few published human studies specifically on this peptide, so its effectiveness is not as well-established as some other anti-aging ingredients.
Slow results
Peptides generally require consistent use over several weeks to months before visible improvements are noticed.
Best for
- Individuals looking for anti-aging benefits with a gentle ingredient
- Those with sensitive skin who want to avoid stronger actives like retinoids
Use caution if
- Those with known allergies to synthetic peptides (rare)
- Anyone seeking immediate results, as peptides work gradually
Usage tips
Safety summary
Heptasodium Hexacarboxymethyl Dipeptide-12 is considered safe for topical use in cosmetics. It has low irritation and comedogenic potential, making it suitable for most skin types. However, as with any new ingredient, a patch test is recommended.
Research notes
Research on this specific peptide is limited. Most evidence comes from studies on similar peptides that support collagen production. More human clinical trials are needed to confirm its efficacy and optimal concentrations.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US when used as directed. Not a drug ingredient.
- Common uses
- Anti-aging serums, Facial moisturizers, Eye creams
- Environmental note
- Synthetic peptides are produced through chemical synthesis, which has a lower environmental impact than animal-derived ingredients but may involve energy-intensive processes.
Good to know
- Peptides are often combined with other anti-aging ingredients like niacinamide or hyaluronic acid for enhanced benefits.
- This ingredient is water-soluble and works well in serum and gel-based formulas.
