Ingredient review
Caffeoyl SH-Heptapeptide-13
INCI: CAFFEOYL SH-HEPTAPEPTIDE-13
A lab-made peptide that may help firm skin and soften expression lines, but human studies are still limited.
In plain English
This ingredient is a small protein fragment (peptide) that has been chemically linked to a caffeoyl group (derived from coffee or similar plants). In skincare, peptides act like tiny signals that tell skin cells to produce more collagen and elastin, which are the proteins that keep skin plump and bouncy. The caffeoyl part may add antioxidant benefits. Because it's a synthetic ingredient, it's designed to be stable and absorb well into skin. However, most of the evidence for this specific peptide comes from lab tests, not large human trials, so results can vary.

Quick decision guide
Useful, but context matters
Caffeoyl SH-Heptapeptide-13 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 Caffeoyl SH-Heptapeptide-13.
- 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 (a short chain of amino acids) modified with a caffeoyl group, used in anti-aging cosmetics to target fine lines and loss of firmness.
How it works
When applied to skin, the peptide portion is thought to mimic natural signaling molecules that stimulate fibroblasts (the cells that make collagen and elastin). The caffeoyl group may help protect the peptide from breaking down too quickly and may also provide mild antioxidant activity by neutralizing free radicals. Together, this can support the skin's structural support network over time.
Pros
Targeted anti-aging support
This peptide is designed to mimic natural signals that boost collagen and elastin, which can help improve skin firmness and reduce fine lines over weeks of consistent use.
Low irritation potential
Because it's synthetic and used at low concentrations, it rarely causes stinging, redness, or breakouts, making it suitable for sensitive skin types.
Cons and cautions
Limited human research
Most evidence for Caffeoyl SH-Heptapeptide-13 comes from lab studies or small trials, so its real-world effectiveness is less established than more studied peptides.
Gradual results
Peptides work slowly — you may need to use a product for 8–12 weeks before noticing visible changes, which can be frustrating for those wanting quick improvements.
Best for
- Adults looking to address early signs of aging like fine lines and loss of firmness
- People with sensitive skin who want a gentle anti-aging option
Use caution if
- Those with known allergies to synthetic peptides (rare)
- Anyone seeking immediate or dramatic results — peptides work gradually
Usage tips
Safety summary
Caffeoyl SH-Heptapeptide-13 is considered safe for cosmetic use at typical concentrations. It has low irritation and comedogenic risks. As with any new ingredient, a patch test is recommended for those with very sensitive skin.
Research notes
Evidence for this specific peptide is emerging. Lab studies suggest it can stimulate collagen production, but large-scale human trials are lacking. It is less studied than classic peptides like Matrixyl or Argireline.
Common label clues
- Typical concentration
- Typically used at 0.5% to 2% in leave-on products
- Regulatory status
- Approved as a cosmetic ingredient in the EU, US, and other major markets. Not classified as a drug ingredient.
- Common uses
- Anti-aging serums, Eye creams, Firming lotions
- Environmental note
- Synthetic peptides are produced in labs, which reduces the need for plant or animal harvesting, but their manufacturing process may involve chemical solvents.
Good to know
- This peptide is often found in higher-end anti-aging serums due to its cost.
- The caffeoyl group is not the same as caffeine — it's a different molecule that may offer antioxidant properties.
