Ingredient review
Caffeoyl SH-Pentapeptide-1
INCI: Caffeoyl SH-Pentapeptide-1
A peptide designed to help reduce fine lines and improve skin firmness by supporting collagen production.
In plain English
This ingredient is a small protein fragment (peptide) attached to a caffeoyl group (derived from coffee or similar plants). In skincare, it works as a signal to your skin cells to produce more collagen and elastin, which are the building blocks that keep skin plump and firm. Over time, this can help soften the look of fine lines and improve skin texture.

Quick decision guide
Useful, but context matters
Caffeoyl SH-Pentapeptide-1 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-Pentapeptide-1.
- 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
Caffeoyl SH-Pentapeptide-1 is a synthetic peptide engineered to mimic natural signaling molecules in the skin. The caffeoyl part is thought to enhance stability and delivery, while the pentapeptide sequence is known to stimulate collagen production.
How it works
When applied topically, the peptide penetrates the upper layers of skin and binds to receptors on fibroblasts (the cells that make collagen). This triggers a cascade that increases collagen and elastin synthesis, helping to reinforce the skin's structural support and reduce visible signs of aging.
Pros
Targeted anti-aging
Specifically designed to support collagen production, which can help reduce fine lines over time.
Gentle on skin
Low irritation and comedogenic risk, making it suitable for most skin types, including sensitive skin.
Cons and cautions
Slow results
Visible improvements typically take weeks to months of consistent use, not overnight.
Cost
Peptide-based products can be more expensive compared to simpler humectants or antioxidants.
Best for
- People looking for anti-aging support without harsh actives
- Those with dry or mature skin wanting improved firmness
Use caution if
- Anyone with known allergies to peptides (rare)
- Those seeking instant results
Usage tips
Safety summary
Caffeoyl SH-Pentapeptide-1 is considered safe for topical use in cosmetics at typical concentrations. It has low irritation and allergy potential, though patch testing is always recommended for new products.
Research notes
Peptides like this one are supported by in vitro and some clinical studies showing collagen stimulation and wrinkle reduction. However, independent long-term human trials are limited, so evidence is moderate.
Common label clues
- Typical concentration
- 0.01% to 0.1%
- Regulatory status
- Approved for cosmetic use in the US, EU, and other major markets. Not a drug ingredient.
- Common uses
- Anti-aging serums, Firming creams, Eye treatments
- Environmental note
- Synthesized in a lab, so no direct plant harvesting impact. Biodegradability data is limited.
Good to know
- Peptides are often listed near the end of ingredient lists because they are effective at low concentrations.
- The 'caffeoyl' group is not caffeine; it is a different compound derived from caffeic acid.
