Ingredient review
Caffeoyl SH-Decapeptide-23
INCI: CAFFEOYL SH-DECAPEPTIDE-23
A lab-made peptide that may help firm skin and soften wrinkles, but research is still early and results vary.
In plain English
This is a man-made ingredient that combines a small protein fragment (a peptide) with a compound from coffee (caffeoyl group). In skincare, it's meant to signal skin cells to produce more collagen and elastin, which can make skin feel firmer and look smoother over time. Think of it as a gentle messenger telling your skin to act younger, but it's not a miracle worker and works best as part of a consistent routine.

Quick decision guide
Useful, but context matters
Caffeoyl SH-Decapeptide-23 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-Decapeptide-23.
- 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
Caffeoyl SH-Decapeptide-23 is a synthetic peptide—a short chain of amino acids—that has been chemically linked to a caffeoyl group (derived from caffeic acid, found in coffee). This combination is designed to improve the peptide's stability and ability to penetrate the skin.
How it works
Once applied, the peptide is thought to mimic natural signaling molecules in the skin, encouraging fibroblasts (the cells that make collagen) to increase production. The caffeoyl group may also provide antioxidant benefits, protecting skin from environmental damage. Over weeks of use, this can lead to improved skin texture and reduced wrinkle depth.
Pros
Gentle on skin
Low irritation and comedogenic risk make it suitable for sensitive skin types, unlike some stronger anti-aging actives.
Dual action
Combines peptide signaling with antioxidant support, potentially offering more than a single-function ingredient.
Cons and cautions
Limited evidence
Most research is preliminary or lab-based, so the real-world effectiveness for humans is not as well-established as for ingredients like retinol.
Slow results
Peptides typically require consistent use over several months to see visible changes, which may test your patience.
Best for
- Adults looking for a gentle anti-aging ingredient to add to their routine
- People with sensitive skin who cannot tolerate stronger actives like retinol
Use caution if
- Those seeking immediate or dramatic results
- Anyone allergic to peptides or caffeic acid derivatives (rare)
Usage tips
Safety summary
Caffeoyl SH-Decapeptide-23 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, especially for those with sensitive skin or allergies.
Research notes
Research on this specific peptide is limited. Most evidence comes from in vitro (lab) studies and a few small human trials on similar peptides. The caffeoyl group may enhance stability and antioxidant activity, but more robust clinical studies are needed to confirm anti-aging benefits.
Common label clues
- Typical concentration
- Typically used at 0.1% to 1% in leave-on formulations
- Regulatory status
- Approved as a cosmetic ingredient in the EU, US, and other major markets. Not classified as a drug or medicine.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Synthetic peptides are produced in labs, which reduces the need for plant or animal harvesting, but their manufacturing may involve energy-intensive processes.
Good to know
- Peptides are fragile; avoid using with very low pH products (like strong AHAs) in the same routine
- The caffeoyl group is not the same as caffeine—it's a different compound with antioxidant properties
